The Use of Stone and Hunting of Reindeer
ARCHAEOLOGY AND ENVIRONMENT 12 THE USE OF STONE AND HUNTING OF REINDEER By Lena Holm O m University of Umeå ° Ai. ^ Department of Archaeology ARCHAEOLOGY AND ENVIRONMENT 12 Distribution: Department of Archaeology, University of Umeå S-901 87 Umeå, Sweden Lena Holm THE USE OF STONE AND HUNTING OF REINDEER A Study of Stone Tool Manufacture and Hunting of Large Mammals in the Central Scandes c. 6 000 - 1 BC. Akademisk avhandling, som för avläggande av filosofie doktors examen vid universitetet i Umeå kommer att offentligt för svaras i hörsal F, Humanisthuset, Umeå universitet, fredagen den 31 januari 1992 klockan 10.00. Abstract The thesis raises questions concerning prehistoric conditions in a high mountain region in central Scandinavia; it focuses on the human use of stone and on hunting principally of reindeer. An analysis of how the stone material was utilized and an approach to how large mammals were hunt ed result in a synthesis describing one interpretation of how the vast landscape of a region in the central Scandinavian high mountains was used. With this major aim as a base questions were posed concerning the human use of stone resources and possible changes in this use. Preconditions for the occurrence of large mammals as game animals and for hunting are also highlighted. A general perspective is the long time period over which possible changes in the use of stone and hunting of big game, encompassing the Late Mesolithic, Neolithic, Bronze Age and to a certain extent the Early Iron Age. Considering the manufacture of flaked stone tools, debitage in the form of flakes from a dwelling, constitute the base where procurement and technology are essential. -

Key to Rocks & Minerals Collections

Boxgrove – c.500ka – is one of the most informative sites at which to analyze 18 shaping strategies and handaxe morphological variability in the European Middle 19 20 Pleistocene, because of the large number of finished handaxes, and the presence of 21 complete operational chains. We focused on the entire handaxe and rough-out sample from 22 Boxgrove-Q1/B with the aim of assessing the role of raw material characteristics – size, form, 23 and homogeneity of nodules – in the shaping process, and to ascertain if they represent real 24 constraints in the production of handaxes. Additionally, given the large number of handaxes 25 and the intensity of the thinning work at Boxgrove, we also aimed to determine if reduction 26 intensity affected the final shape to the degree that some authors have previously postulated. -
Standing at the Gates of Europe: Human Behavior and Biogeography in the Southern Carpathians During the Late Pleistocene

Using a whole assemblage behavioral indicator, we show that the hominins that manufactured those stone tools do not appear to have differed in terms of the flexibility of the mobility strategies they employed to exploit their landscapes. Rather than biological change, we argue that large-scale climate changes are likely more important drivers of behavioral changes during the Late Pleistocene of the region, including during the Middle–Upper Paleolithic transition. These results agree well with the results of studies having employed this methodology -
"References" at End. 38- of 'Siliceous' by Nearly 60 Years
TERMINOLOGY OF H CHEMICAL SILICEOUS SEDIMEWS* W.A. Tarr "Chert. -- The origin of the word 'chert' has not been determined. The Oxford Dictionary suggests it was a local term that found its way into geological usage, 'Chirt' (now obsolete) appears to have been an early spelling of the word. In comparison with 'flint, ' chert' is a very recent word. 'Flint,' from very ancient times, was applied to the dark varieties of this siliceous material. Apparently, the lighter colored varities, now called 'chert,' were unrecognized as siliceous material; at any rate, no name describing the material has been found in the very early literature. The first specific use of the word 'chert' seems to have been in 1729 (i) when it was defined as a 'kind of flint, The French name for chert is com- monly given as silex corne (horn flint) or silex de la craie (flint of the chalk), but Cayeux states that the American term 'chert' corresponds to the French word silexite. He- uses chert to designate a related material occurring in siliceous beds (3). The German term for chert is Hornstein. 'Phtanite' (often misspelled Tptanitet) has been used as a synonym for chert. Cayeux uses the term synonymously as the equivalent for silexite, and 'hornstone' has also frequently been so used. So common was the use of the term 'hornstone' during the early part of the last century that there is little doubt that it was then the prevalent name for the material chert, as quotations given under the discussion of hornstone will show. But most common among the synonyms for 'chert' is 'flint,' and since 'flint' had other synonyms, 'chert' acquired many of them. -
About Our Mineral World
About Our Mineral World Compiled from series of Articles titled "TRIVIAL PURSUITS" from News Nuggets by Paul F. Hlava "The study of the natural sciences ought to expand the mind and enlarge the ability to grasp intellectual problems." Source?? "Mineral collecting can lead the interested and inquisitive person into the broader fields of geology and chemistry. This progression should be the proper outcome. Collecting for its own sake adds nothing to a person's understanding of the world about him. Learning to recognize minerals is only a beginning. The real satisfaction in mineralogy is in gaining knowledge of the ways in which minerals are formed in the earth, of the chemistry of the minerals and of the ways atoms are packed together to form crystals. Only by grouping minerals into definite categories is is possible to study, describe, and discuss them in a systematic and intelligent manner." Rock and Minerals, 1869, p. 260.

Mar- Snowflake Obsidian
Learning Series: The Wonder and Natural Beauty of Rocks Snowflake Obsidian By Leslie A. Malakowsky Obsidian is mineral-like, but it is not a true mineral. It’s a naturally occurring volcanic glass that forms as an extrusive igneous rock. (Glass is an amorphous, homogeneous material with a random liquid-like structure that generally forms due to rapid cooling.) Obsidian is sometimes classified as a mineraloid, a mineral-like substance that does not display crystallinity. Obsidian is a mixture of cryptocrystalline grains of silica minerals in a glass-like suspension, a super-cooled liquid. In the last stages of volcanic eruptions, when most of the other elements and the water in the lava are gone (burned up, ejected or flowed out), the remaining material chills at surface temperatures. “Snowflake” obsidian is a variety of obsidian that is usually black with white, off-white or light brown snowflake-shaped crystal patches of the mineral cristobalite. Cristobalite is a silica polymorph (the ability of a solid material to exist in multiple forms or crystal structures) that, in the case of snowflake obsidian, forms as crystals or spherulites during partial crystallization as the glass cools. Other names for this variety of obsidian are “flowering” obsidian and “spherulitic” obsidian. Obsidian was named after the Roman explorer Obsius because of its resemblance to a stone he found in Ethiopia that he named obsianus lapis. And the English translation of Natural History, an early encyclopedia originally written in Latin by Pliny the Elder, includes a few sentences about a volcanic glass called Obsidian. Obsidian is commonly found within the margins of rhyolitic lava flows known as obsidian flows. -
