Research on recognition of the geologic framework of porphyry copper deposits on ERTS-1 imagery

The author has identified the following significant results. Many new linear and circular features were found. These features prompted novel tectonic classification and analysis especially in the Ray and Ely areas. Tectonic analyses of the Ok Tedi, Tanacross, and Silvertone areas follow conventional interpretations. Circular features are mapped in many cases and are interpreted as exposed or covered intrusive centers. The small circular features reported in the Ok Tedi test area are valid and useful correlations with tertiary intrusion and volcanism in this remote part of New Guinea. Several major faults of regional dimensions, such as the Denali fault in Alaska and the Colorado mineral belt structures in Colorado are detected in the imagery. Many more faults and regional structures are found in the imagery than exist on present maps

Ceramic Resource Selection and Social Violence in the Gallina Area of the American Southwest

This dissertation examines the relationship between social violence and ceramic resource procurement. Do people in middle-range societies alter resource use in response to conflict? Specifically, does social strife influence the distance to which potters in middle-range societies will travel to collect ceramic resources? Distance and quality are primary elements in clay selection. Clay is heavy, so for many potters distance is the determining factor in clay selection (Arnold 1985, 2000). Arnold (1985, 2000) estimated procurement thresholds using worldwide ethnographic data from 111 traditional societies. He found that for both clays and tempers, people prefer to travel only one kilometer, but they will go up to four kilometers if necessary. These thresholds were the basis for the field component of this research. Pottery production occurred throughout the American Southwest under conditions of pervasive conflict in the 13th century A.D. The Gallina area is an ideal location for investigating resource procurement and social violence in northwestern New Mexico. Conflict in this area is evidenced by defensive architecture, such as towers and cliff houses (Haas and Creamer 1985; Mackey and Green 1979; Schulman 1949, 1950), burned structures with human remains (Gallenkamp 1953; Hibben 1944; Mackey and Green 1979), and human remains with embedded projectile points and skull trauma (Chase 1976; Mackey and Green 1979). Two sites in the Gallina area were chosen, one with a defensive setting and architecture the other with an open site plan and no defensive structures. Ceramics from each of the sites and the clay resources in proximity to the sites were examined to see if conflict affected resource selection. X-ray diffraction (XRD) determined the clay mineralogy of ceramic pastes and the collected natural clays, petrography identified the aplastic mineralogy of the sherds and collected samples, and inductively coupled plasma-mass spectrometry (ICP-MS) provided the chemistry of the ceramic pastes and the natural clays. Numerous field and laboratory characterizations provided more information about the qualities of the available clays and the ceramics themselves. The combined results of the laboratory tests, mineralogical studies, and chemical comparisons indicate that Gallina potters did not alter their resource selection in response to social violence

List of Bureau of Mines publications and articles, January 1, 1960, to December 31, 1964 with subject and author index

The Bureau of Mines was establis4ed in the public interest to conduct inquiries and scientific and technologic investigations concerning mining and the preparation, treatment, and utilization of mineral substances; to promote health and safety in the mineral industries; to conserve mineral resources and prevent their waste; to further economic development; to increase efficiency in the mining, metallurgical, quarrying, and other mineral industries; and to inquire into the economic conditions affecting these industries. The organic act of the Bureau, as amended by Congress and approved February 25, 1913, made it the province and duty of the Bureau to "disseminate information concerning these subjects 'in such manner as will best carry out the purposes of this Act.\ue2\u20ac?In accordance with that directive, the Bureau reports the findings of its research and investigations in its own series of publications and also in articles that appear in scientific, technical, and trade journals; in proceedings of conventions and seminars; in reference books; and in other non-Bureau sources. The number of these reports, the wide range of subjects they cover, and the variety of mediums in which they appear make the kind of list and index presented in this special publication both necessary and valuable. This issue describes Bureau reports and articles published during the period January 1, 1960 to December 31, 1964. It supplements the 50-year list of Bureau publications issued from July 1, 1910, to January 1, 1960, and the 50-year list of articles by Bureau authors published outside the Bureau from July 1, 1910, to January 1, 1960. It supersedes the annual lists of Bureau publications and articles from January 1 to December 31, 1960, from January 1 to December 31, 1961, from January 1 to December 31, 1962, and from January 1 to December 31, 1963.7The leading general and technical libraries of the United States maintain files of the Bureau's publications. A list of these libraries appears immediately following this introduction
