Abstract:

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 conclusi-on 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；metallogen-
ic epoch is Late Triassic-Early Jurassic；type of Dailong gold deposit is the mesothermal alteration.This study provi-
des reference for the further research on the metallogenic characteristics and the geological prospecting activities.
