The original intent was to identify potential so 0urces of raw materials for tools used by indigenous people of northern Nevada. 0 The dataset was created to assist governmental agencies and others in making r 0esource management decisions through the use of geographic information systems 0(GIS). Uses of the spatial data set include, but are not limited to natural, a 0nd cultural resource management, interdisciplinary activities, recreational roc 1khounding, and gold exploration. 0 The primary focus of this data was potential raw material sites fo 0r tools made by native northern Nevadans. Archaeologists routinely rely on pot 0tery and projectile points for dating techniques. Since basketry was used most 0 in the nomadic lifestyle of the native northern Nevadans, the major dating dev 0ice for the Great Basin archaeological sites has been the projectile point. Pre 0liminary investigation of the types of raw materials used for tool making by in 0digenous people of Northern Nevada led to decisions regarding the kind of occur 1rences considered to be cryptocrystalline for this data set. 1 en 1 1 1 1 1995 1 1 1 1 MRDS Version 1 1 1 Complete 1 None planned 1 1 1 1 -179.4275 1 -173.89616 1 41.95434 1 39.71288 1 0 294406.906250754 0756.8125004400999.0000004646653.500000 1 1 1 none 1 chalcedony 1 opal 1 jasper 1 chert 1 silica 1 1 1 none 1 Northern Nevada 1 1 1 None 0 For use at 1:750,000 scale.

The original MRDS 0 database field ACC was intended to indicate the positional accuracy of each re 0cord, and was entered by the person who created or updated the record. 1 0 Point topology. These data are believed to be logically consistent, a 0lthough no formal tests were performed. Because of multiple sources, data cha 1racteristics may not be consistent. 0 The area of interest was within the northern Nevada state boundary 0and bounded in the south by 39 degrees north latitude. The cryptocrystalline ma 0terials that the comprise the data set are chalcedony, opal, jasper, chert, and 1 silica. 1 1 0 Positional accuracy is variable among the MRDS records in the dat 0abase because the data came from multiple sources and no consistent program has 0 been implemented to verify the accuracy of the positional information. The da 0tabase field ACC contains an indicator of the accuracy of the information in th 0e record, which generally focuses on the positional accuracy but may in some ca 1ses refer to attributes as well. 1 1 1 1 1 1 1 U.S. Geological Survey database 1 1995 1 Minerals Resources Data System (MRDS) 1 1 Reston, VA 1 U.S. Geological Survey 1 1 1 1 digital database 1 1 1 1 1995 1 1 1 1995 1 1 MRDS, 1995 1 Cryptocrystalline site locations 1 1 0 Several search strategies were designed to capture records from t 0he MRDS database that represented cryptocrystalline occurrences.
