It was proved that this deposit was mainly controlled by the Omeishan basalt, layer-structure in the basalt and regionalgeochemistry.
结果表明，该矿床主要受峨眉山玄武岩、玄武岩中的层间构造以及区域地球化学的控制。

Regionalgeochemistry anomaly in mining deposit was well-developed, and anomaly distribution is controlled by sill and swarm of basic and ultrabasic rock.
During the disposal of regional geochemical data, the key is confirmation of anomalous threshold, which is also a fundamental issue in explorative geochemistry.
