Geological and borehole geophysical data and observations collected to characterize the basin and its surface and groundwater flow systems with primary focus on the physical characteristics of the fault vein, related mine workings, and surrounding bedrock
Petrographic and geochemical analyses of 50 outcrop samples and 58 drill core samples.
Hydrothermal orebodies and their host rocks are characterized by compositional variations in magnetite. Minor and trace element data for hydrothermal and igneous magnetite are compared with an unmineralized magnetite-series granodiorite in southwest Japan
The purpose of this report is to present available petrographic and geochemical data for unmineralized rock samples, principally volcanic rocks and to make those data available to ongoing petrogenetic investigations of these rocks.
This report describes key features; identifies tectonic-sedimentary environments; illustrates geochemical, geophysical, and geoenvironmental characteristics; evaluates deposit formation; presents exploration and assessment guides; and lists knowledge gaps
Geochemical and mineralogical analyses of plutonic rock samples
The data consist of major- and trace-element whole-rock geochemical analyses and major- and trace-element analyses of sulfide minerals determined by electron microprobe and laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS) techniques
