Dashui Gold Deposit which was found in west Qinling mountain area was a type of gold deposits with extremely unique mineralization characteristics in Maqu, Gansu province, China. The tectonic location of the deposit belonged to Qin-Qi-Kun orogenic belt, west Qinling south subzones zone. T2m in the Middle Triassic was the main gold ore-bearing horizons; it was close to the ultra-shallow-shallow-intermediate-acid igneous rocks of Indosinian-Yanshanian in time and space. The ore bodies mainly occurred in the hematite of silicified limestone, hematite of silicified granodiorite and its contact zone. The shape of the ore bodies was complex; it might be irregular-shaped twig, layered, lenticular, hollow-like, tubular and nervation, etc. The mineralization intensity was closely related to the silicification and hematitization. The ore was red, brown and very poor in sulfides. The deposit was shallowly buried with high grade and simple mineral composition. It was of high economic value for its easy acquisition and sorting. The main mineralization control factors were stratum, structure, rock mass and vein rock.
