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. -

Prehistoric Lithic Technology} Workshops} and Chipping Stations in the Philippines
Prehistoric Lithic Technology} Workshops} and Chipping Stations in the Philippines D. KYLE LATINIS THE PHILIPPINE ISLANDS represent an important area for research of problems concerning prehistoric archaeology in Southeast Asia. These insular areas, located east of the biogeographic boundary known as Huxley's line, include a variety of tropical environments. These islands remained detached from the continental portion of Southeast Asia throughout the Pleistocene and Holocene. Archaeolog ical research has documented human occupation and adaptation from at least the Late Pleistocene and Early Holocene within these islands. Unfortunately, relatively little intensive prehistoric archaeological research has been undertaken in the Philippines compared to some areas in mainland South east Asia, Oceania, and Australia. Warren Peterson's dissertation (1974) focused on a series of sites in northern Luzon and represents one of the foundation stud ies in the Philippines for modern archaeology. Peterson's work has often been cited and his conclusions used for the development of models concerning prehis tory in the Philippines and Southeast Asia. Peterson's research was conducted during a period when behavioral reconstruc tions from site assemblage analyses were prominent in archaeological research. Specifically, Peterson attempted behavioral reconstruction from the analysis of stone tools from the Busibus/Pintu site in northern Luzon, Philippines. A reanal ysis of the entire Busibus/Pintu lithic assemblage has revealed problems with Peterson's initial analysis and interpretation of this site-problems that will be addressed in this paper. Lithic technology, stone tool manufacture, and selection and reduction strategies will also be explored. Finally, new interpretations of the nature of the lithic assemblage and site activities at Busibus/Pintu rock shelter will be provided. -

"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. -
47. Chert and Porcellanite from Deep Sea Drilling Project Site 436, Northwest Pacific
47. CHERT AND PORCELLANITE FROM DEEP SEA DRILLING PROJECT SITE 436, NORTHWEST PACIFIC K. A. Pisciotto,1 Earth Science Board, University of California, Santa Cruz, California ABSTRACT Cretaceous chert and porcellanite recovered at Site 436, east of northern Honshu, Japan, are texturally and mineralogically similar to siliceous rocks of comparable age at Sites 303, 304, and 307 in the northwest Pacific. These rocks probably were formed by impregna- tion of the associated pelagic clay with locally derived silica from biogenic and perhaps some volcanic debris. Fine horizontal lamina- tions are the only primary sedimentary structures, suggesting mini- mal reworking and transport. Collapse breccias and incipient chert nodules are diagenetic features related to silicification and compac- tion of the original sediment. Disordered opal-CT (^[101] = 4.09 Å) and microgranular quartz (crystallinity index < 1.0) are the two common silica minerals pres- ent. Some samples show quartz replacing this poorly ordered opal- CT, supporting the notion that opal-CT does not become completely ordered (i.e., d[101] = 4.04 Å) in some cases before being converted to quartz. The present temperature calculated for the depth of the shallowest chert and porcellanite at this site is 30 °C; this may repre- sent the temperature of conversion of opal-CT to quartz. High reflection coefficients (0.29-0.65) calculated for the boundary be- tween chert-porcellanite and clay-claystone support the common observation that chert is a strong seismic reflector in deep-sea sedimentary sections. INTRODUCTION This paper discusses the petrology and origin of cherts and porcellanites at Site 436. In addition, the Keene's (1975, 1976) comprehensive work on cherts temperature of formation and acoustic impedances of and porcellanites from the North Pacific clearly demon- these siliceous rocks are calculated. -
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.
