| Abstract: | The Jinjiawan gold ore deposit in Luoning County, Henan Province, occurs in Shibangou formation gneiss of Taihua Group on the sourthern margin of North China platform. The gneiss has been altered in to yellow-grey rock mass. The ore is mainly contaminated and altered network of veins and less sulphide-quartz veins. This gold ore deposil was discovered by the authors in June, 1988. Nine samples were collected. Gold content is 108.93 g/t to 1.5g/t. Mineralization zone in the deposit is 1000m long, and altered zone 20-30m wide is composed of four quartz veins which was excavated by some workers. This gold ore deposit occurs in tectonically altered genesis in the greenstone belt. |
