Stone dating techniques

Although the dividing line between the Lower and Middle stages is not so clearly defined as that separating the Middle and Upper subdivisions, this system is still used by most workers. Lower Paleolithic On the basis of the very rich materials from the Somme Valley in the north of France and the Thames Valley in the south of England, two main Lower Paleolithic traditons have been recognized in western Europe. These are as follows: The type tools of the Abbevillian formerly Chellean , which takes its name from the town of Abbeville, France, on the metre foot terrace of the Somme Valley, consist of pointed, bifacial implements, or hand axes. Their forms vary, and the flaking is generally irregular; it is probable that they were manufactured either with a stone hammer or on a stone anvil. Associated with these crude types of hand axes, simple flake tools are found, but they lack definite form. The Abbevillian has been reported from deposits of lower Pleistocene First Interglacial age. The Acheulean, which begins in the Second Interglacial and persists to the close of the Third Interglacial, covers by far the longest time span of any of the Paleolithic traditions found in western Europe. The type site is on the metre terrace of the Somme Valley at St. Acheul, near Amiens, in northern France. Acheulean hand axes, which display a marked technological refinement over their Abbevillian precursors , were apparently made by employing a wooden or bone billet rather than the more primitive stone-on-stone technique. But, except at the very end of the Acheulean cycle of development, there is very little typological difference in the types of hand axes found in the various layers. The Micoquian , or Final Upper Acheulean, is characterized by elongated hand axes that exhibit very straight and finely chipped edges, in marked contrast with the Lower Acheulean, in which ovate forms predominate. Flake tools occur in all Acheulean levels, the side scrapers being the predominant type. Many of these tools were made from trimming flakes produced during the process of hand-ax manufacture. In general, flake tools, including points with a triangular cross section , are found in greater quantities in Micoquian deposits than in the older horizons. The evidence from Clacton-on-Sea, Essex, and Swanscombe, Kent, in the Thames Valley of southeastern England clearly shows that the main development of the Clactonian occurred during early Second Interglacial times. The type artifacts are flakes, although core tools—single-edged choppers and chopping tools—do in fact occur. Actual retouching or secondary working of the edge is found in some instances, but for the most part it is crude, and edge chipping resulting from use is far more characteristic. Named after a locality at Levallois, a suburb of Paris, the Levalloisian is primarily a flake tradition, although hand axes are found in certain of the Middle and Upper Levalloisian stages. It is characterized by a new and improved method of producing flakes, which previously had been obtained in a more or less haphazard manner. This involves the careful shaping of the core by the removal of centrally directed flakes, and the preparation of an extremity for the detachment of a symmetrical oval flake. Since unstruck cores of this type exhibit a plano-convex section suggesting the form of a tortoise, they are known as tortoise cores. On the striking platforms of typical levallois flakes, small vertical flake scars, called facets, may be observed, and the scars of the converging core-preparation flakes are present on the upper surface. The use of this technique resulted in the production not only of symmetrical flakes but also of larger ones in proportion to the size of the core. In the Middle and Upper Levalloisian a variation of this same basic technique was developed whereby it was possible to produce either triangular flakes or points or rectangular flakes or flake blades by modifying the method of core preparation. Middle Paleolithic The Middle Paleolithic comprises the Mousterian , a portion of the Levalloisian, and the Tayacian , all of which are complexes based on the production of flakes, although survivals of the old hand-ax tradition are manifest in many instances. Associated with the Tayacian, in which the artifacts consist of very crude flakes, remains of modern humans Homo sapiens have been found. The Mousterian industry , on the other hand, is associated with the Neanderthals. By the s no human remains had yet been found associated with the Levalloisian. It is in the Mousterian levels of the caves and rock shelters of central and southern France that the earliest evidence of the use of fire and the first definite burials have been discovered in western Europe. The typology of the artifacts is complex; it consists of three distinct increments: The type artifacts from the Mousterian consist of points and side scrapers, in addition to a few hand axes especially heart- or triangular-shaped forms , and the secondary working is coarse. A crude bone industry appears here for the first time. Judging by what is known concerning modern hunting groups, small bands or tribes of people already had developed simple social institutions, even at this early level of development. Early humans made their greatest cultural progress at this time. The hand axes and flake tools of the earlier assemblages were replaced by diversified and specialized tools made on blades struck from specially prepared cores. Many important inventions appeared, such as needles and thread, skin clothing, hafted stone and bone tools, the harpoon , the spear thrower, and special fishing equipment. Bone, ivory, and antler, in addition to flint, were extensively used. The earliest man-made dwellings are found, consisting of semisubterranean pit houses. Of prime importance and interest is the beginning of the basic techniques of drawing, modelling, sculpture, and painting , as well as the earliest manifestations of dancing , music , the use of masks, ceremonies, and the organization of society into patterns that were apparently fairly complex. Indeed, the location of certain settlements suggests a more complex social life, including perhaps collective hunting. There is evidence for fertility magic, private property, and possible social stratification. Furthermore, primitive types of early humans disappeared, and the remains of humans of modern type Homo sapiens alone are found in Upper Paleolithic sites. These latter occur, together with gravers or burins , end scrapers, points, etc. The graver itself is a very important tool, for its invention made possible the extensive working of bone and facilitated the development of art. The climate of the Upper Paleolithic varied from cold steppe, or even Arctic tundra, to north temperate taiga , similar to parts of Siberia and Canada of the present day. These first appear, together with other types of blade tools, in horizons immediately overlying Upper Mousterian levels. The tool types include various kinds of steep-ended scrapers, nose scrapers, blades with heavy marginal retouch, strangulated blades, busked gravers or burins , and split-base bone points. Articles of personal adornment, probably worn as necklaces, such as pierced teeth and shells, as well as decorated bits of bone and ivory, appear for the first time in the Aurignacian. In general, Upper Paleolithic art falls into two closely related categories: The former includes finger tracings, paintings, engravings, bas-reliefs, and sculptures on the walls of caves and rock shelters; the latter is characterized by small engravings and sculptures on stone and bone found in the occupation layers. The whole development almost certainly owes its inspiration to the magico-religious idea, especially the custom of hunting magic as practiced today by living primitive peoples. In addition, the usual types of gravers, end scrapers, points, perforators, etc. Examples of Solutrean art are comparatively rare; they consist of sculpture in low relief and incised stone slabs. The fauna indicates that this culture flourished in a relatively cold climate. This final culture of the Upper Paleolithic is noted for the dominance of bone and antler tools over those of flint and stone and for the very remarkable works of art that were produced at this time. The flint and stone tools include a variety of special forms, among which small geometric forms, denticulated blades, scrapers with steeply retouched edges, and the parrot-beak graver are especially distinctive. The six phases of the Magdalenian have been established stratigraphically and are characterized mainly by the contained bone and antler implements. But the heights attained by the people responsible for this culture can best be evaluated on the basis of the art objects they produced. Magdalenian sites have yielded countless fine examples of both mural and portable art. Animals of the period, the usual subject matter, are portrayed in paintings often polychrome , engravings, and sculptures. The fauna from the various Magdalenian horizons demonstrates that cold conditions prevailed in western Europe at the end of Paleolithic times. Cultural adaptations appear to have been made to restricted local areas or niches and to the fluctuations of climate and environment during the changing phases at the end of the Pleistocene range of time. In fact, it could be maintained generally that Upper Paleolithic traditions flowed rather smoothly into the Mesolithic, with no more significant indication of cultural development than further environmental readaptations. A classic example of such traces comes from the Maglemose bog site of Denmark, although there are comparable materials ranging from England to the eastern Baltic lands. These bogs were probably more or less swampy lakes in Mesolithic times. At about bce, when the Maglemosian culture flourished, traces of primitive huts with bark-covered floors have been found. Flint axes for felling trees and adzes for working wood have appeared, as well as a variety of smaller flint tools, including a great number of microlithic scale. These were mounted as points or barbs in arrows and harpoons and were also used in other composite tools. There were adzes and chisels of antler or bone, besides needles and pins, fish-hooks, harpoons, and several-pronged fish spears. Some larger tools, of ground stone e. Wooden implements also have survived because of the unusually favourable preservative qualities of the bogs; bows, arrow shafts, ax handles, paddles, and even a dugout canoe have been discovered. Fishnets were made of bark fibre. There is good evidence that the Maglemosian sites were only seasonally occupied. Deer were successfully hunted, and fish and waterfowl were taken, and it appears possible that several varieties of marsh plants were utilized. At Star Carr, in northern England, there are indications that four or five huts existed in the settlement, with a population of about 25 people. This description of the Maglemosian must suffice to represent a considerable variety of European manifestations of the level of intensified post-Pleistocene food collecting. The catalogs of the Azilian and Tardenoisian industries of western Europe, of the Ahrensburgian of northern Germany, of the Asturian of Spain, etc. The Nachikufan As a further and far-distant example, the Nachikufan culture of southern Zimbabwe might be cited. Here again, microlithic flint bladelet tools, with certain types mounted as projectile points or in composite tools, existed. Ground-stone axes and adzes, bored stones digging-stick weights? Grindstones of various types indicate a degree of dependence on collected vegetable foods, and the animal bones suggest specialization in the hunting of zebras, wildebeests, hartebeests, and wild pigs. These Nachikufan materials date back to at least bce. Again, an intensified level of food collecting is implied. The general picture Though there are vast gaps in our knowledge of the Holocene Period in many parts of the Old World, enough is known to see the general cultural level of this range of time. Outside of the regions where food production was establishing itself, the period was one of a gradual settling-in and of an increasingly intensive utilization of all the resources of restricted regional niches. But, as time went on, certain climaxes within the matrix of an intensified level of food collection did occur. An often-cited example might be the complex art and social organization of the cultures of the northwest coast of British Columbia. Neolithic The origins and history of European Neolithic culture are closely connected with the postglacial climate and forest development. The increasing temperature after the late Dryas period during the Pre-Boreal and the Boreal c. Thus, the Mediterranean zone became the centre of the first cultural modifications leading from the last hunters and food gatherers to the earliest farmers. This was established by some important excavations in the midth century in the Middle East , which unearthed the first stages of early agriculture and stock breeding 7th and 6th millennia bce with wheat, barley, dogs, sheep, and goats. Early prepottery Neolithic finds probably 6th millennium bce have been made in the Argissa Magula near Larissa Thessaly, Greece , while excavations in Lepenski Vir Balkan Peninsula have brought to light some sculptures of the same period. The independent origin of European Neolithic was established, and it was thought highly probable that the cradle of farming in the Middle East had not been the only one: Each zone itself is subdivided into natural regions by physiographic boundaries and peculiarities of climate or soil. Only the three major divisions of the temperate zone are not obvious from every map. The substantial Neolithic communities that arose by bce must have been largely recruited from indigenous Mesolithic hunters and fishers, attested to so abundantly in western and northern Europe by various remains. Some communities indeed seem to be composed entirely of such Mesolithic stocks, though they had adopted a Neolithic equipment from immigrant farmers; such are sometimes termed Secondary Neolithic.

  1. In Achaemenid quarries wedge-shaped holes averaging about 20 cm long, 8 cm wide, and cm deep can be observed at wide intervals.

  2. Made from sand and aggregates, fiberglass reinforcement, cement, and integrated pigment.

  3. In the 19th century the European round arch gained increasing influence; by the end of the century it had, however, given way to the basket-shaped arch with its much wider span, again especially in bridge construction. The rural economy permitted the continuous occupation of permanent villages around the Aegean and in the Balkan Peninsula , perhaps also in southern Italy and the Iberian Peninsula. The more usual adaptation of the Greek rectangular temple is to be seen today in the example at Nimes in France, known as the Maison Carree.

  4. A temple-like forecourt or porch lies against an immense foot wide circular hall or rotunda, under a low dome. The partly worked stone blocks, like those in the terrace at Persepolis, were brought on wheels drawn by work animals over inclined tracks leading to the construction area.

  5. The difference between high end cast stone and normal precast concrete is easily seen, and even the novice can appreciate the high quality limestone like finish on a cast stone product.
