Disseminated microscopic gold grains, measuring 8-12 microns across and possessing a fineness of 950 to 960 have been observed in the quartz normative tholeiitic lava flows from the Amarkantak region of the Eastern Deccan Volcanic Province. High temperature of equilibration (1060-1470°C) and very low oxygen fugacity (<5) as determined from the co-existing ulvospinel-magnetite and ilmenite-hAematite pairs are proposed to be the controlling factors for the occurrence of gold in these volcanics.
