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...

Line, grid, and vector data, and maps for the airborne geophysical survey of the Slate Creek�Slana River Survey, Chistochina mining district, south-central Alaska

This digital publication, GPR 2009-1, contains data produced from airborne geophysical surveys conducted in 2008 for the Slate Creek�Slana River survey area in the Chistochina mining district, south-central Alaska. Aeromagnetic and electromagnetic (EM) data were acquired by helicopter for about 442 sq miles. Fugro Airborne Survey's frequency-domain DIGHEM V system was used for the EM data. GPR 2009-1 includes (1) raw and processed linedata; (2) gridded data; (3) vector files of data contours and flight lines; and (4) maps of the data.
