Abstract
application/pdf
The Takamine gold deposits in Cretaceous biotite-hornblende-granodiorite found in Iwate Prefecture, Japan, belong to epithermal fissure filling vein. Ores of these deposits consist mainly of goethite and quartz with a small quantity of pyrite, native gold, chlorite and sericite. Native gold is always intimately associated with goethite and pyrite, and goethite results from the supergene alteration of pyrite originally formed from hydrothermal origin. The chemical analysis, differential thermal analysis curve and X-ray data of gold-bearing goethite are given.
