Abstract:

The discovery of Elashankou silver-lead-zinc deposit is a major breakthrough in the prospecting of Elashan metallogenic belt in Qinghai Province.This deposit is mainly produced in terrestrial volcanic rocks of the Late Triassic（Elashan group）.We discuss the geological conditions of the silver -lead-zinc deposit based on years of exploration results about the formation,structure,igneous rock,wall rock alteration,ore-controlling factors and metallogenic regularity,etc.We suggest that the deposit is impacted by the volcanic eruptions and acidic lava,and the ore produces in the complex（rhyolitic,andesitic,dacitic） volcanic breccia tuff lava combination,formed copper-silver-lead-zinc body in which pyrite is predominant，based on this,with the superimposed of the acidic magma intrusion in late NW-trending faults,eventually formed deposits pattern,which is controlled by the volcanic bodies and NW-trending faults.Comprehensive analysis show that the deposit belongs to terrestrial volcano-subvolcanic type （hydrothermal） deposits.

Key words: Geological characteristics, Subvolcanic, Silver-Lead-Zinc deposit, Ore-controlling factor, Metallogenic regularity, Prospecting indicators, Elashan, Qinhai Province
