STUDY OF THE GENETIC MINERALOGY OF GOLD DEPOSIT OF THE YINDONGPO IN TONGBE, HENAN PROVINCE.

The deposit concerned is a large gold deposit explored recently in Henan Province. It can be opencut mined because of its shallowness. The associated silver, lead, zinc etc. are valuable in comprehensive utilization. The genesis of the deposit has its features and attracts the attention of geologists. This paper describes the typical characteristics of the gold and silver minerals and the main gold-containing sulphide closely associated with it - pyrite, sphalerite, galena. The author calculated the principal crystallographic parameters of these mineral by using computer program and obtained some genetic information of mid-low temperature metamorphic epithermal gold deposit in strata-bound volcano deposit.
