Major-oxide, minor-oxide, and trace-element geochemical data from rocks collected in the Chistochina mining district, Mount Hayes Quadrangle, Alaska, in 2005-2009 Mineral-resources personnel from the Alaska Division of Geological & Geophysical Surveys (DGGS) carried out a geological field survey, including mapping and sampling in the Chistochina mining district in the Mount Hayes A-2 and A-3 quadrangles, Alaska, from June 30 to July 15, 2009. The fieldwork provides basic information critical to building an understanding of Alaska's geology and is part of an integrated program of airborne geophysical surveys followed by geological mapping. During 2009, 57 rock samples were collected for geochemical trace-element analysis, 107 rock samples were collected for whole rock (major- and minor-oxide and petrogenetically important trace elements) analyses, and 2 samples were collected...

The original geochemical data set included 1013 stream-sediment samples, (Albanese, 1982a-c). Tags: Fairbanks, Fairbanks Mining District, Geochemical Data, Geochemistry, Livengood, All tags...

This mapping is one component of the multi-year DGGS project studying the geology, geohazards and resources along the proposed gas pipeline corridor from Delta Junction to the Canadian border. In 2006, we collected 10 samples for whole rock (major- and minor-oxides, and petrogenetically important trace-elements) analysis. In 2007, we collected 111 samples for whole rock analysis and 36 rock samples for geochemical trace-element analysis....

Users define the suite of sample analyses to be displayed by selecting sample and analysis types and either a geographic area or a previously compiled dataset. The data is stored in the DGGS Geologic and Earth Resource Information Library of Alaska (GERILA) digital database. The display tables are designed to provide documentation of the search criteria, samples, analyses, and individual geochemical determinations to the level reflected in their source publications or in project files to the best of DGGS staff's ability. The source GERILA dataset is incomplete and is added to as more data can be formatted and...
