GENETIC TYPES AND GEOLOGICAL FEATURES OF THE GOLD DEPOSITS IN NORTHERN JIANGXI PROVINCE

The gold deposits, related to volcanic-subvolcanic-porphyry metallogenic series of Yanshan epoch in Northern Jiangxi Province, belong to one of the most important gold metallogenic series. Based on the derivation of metallogenic matters, mineralization and wallrock conditions, the gold deposits are subdivided into three main types:volcanic thermal type, subvolcanic rock-shallow to ultra-shallow porphyry thermal type, and concealed explosive breccia type of gold deposits. In order to promote and guide the prospecting of gold in Northern Jiangxi Province, the authors discuss the geological features, criteria and directions for ore-prospecting.
