Metallogenic Regularity and Prospecting Prediction of Liaojiaping Gold Deposit in Hunan Province
The Liaojiaping gold deposit is located in the Chengbu-Taojiang antimony gold polymetallic metallogenic belt.By studying the geological characteristics of the mining area,the geological characteristics of the deposit and the analysis of the metallogenic law,the prospecting prediction is made.The outcropping strata in this area are Sinian,Cambrian,Ordovi-cian,Silurian and Devonian,among which the Ordovician and Silurian are the main ore-bearing strata of gold.The west side of the mine is dominated by NW oriented ore-controlling and ore-bearing structure,while the east side is dominated by NE oriented ore-controlling and ore-bearing structure.Early granite is closely related to the formation of gold deposits.The analysis shows that:Chengbu-Taojiang deep fault and its side;Outer contact zone of early Indochinese granite porphyry;structural change and intersection position;sand-argillaceous sedimentary rock formation and its NW tectonic fracture zone;the superposition of silicification,pyritization and decolorization and the periphery of the discovered gold belt are good pros-pecting areas.
