Geological Characteristics and Genesis of Dailong Gold Deposit in Sichuan Province

Dailong Gold deposit was found in 2005,but geological prospecting is still in pre-investigation stage.Through the researching of regional geology background,deposit geology,material source and genesis,the conclusion is that orebodies which is hosted in Upper Triassic Xinduqiao group is controlled by the rock and tectonic;the ore type is the broken alteration slate and granite porphyry;the main gold-bearing minerals are pyrite,arsenop yrite and stibnite;ore-forming material is from strata and magma,having the medium temperature range;metallogenic epoch is Late Triassic-Early Jurassic;type of Dailong gold deposit is the mesothermal alteration.This study provides reference for the further research on the metallogenic characteristics and the geological prospecting activities.
