A review on the chronology of micro-disseminated gold deposits in Yunnan-Guizhou-Guangxi triangle area,southwestern China;

In last 30 years,many important prospecting clues and targets of micro-disseminated gold deposits,which are difficult to distinguish by naked eyes,were provided according to exploration geochemical gold anomalies.

Fluid inclusions from micro-disseminated gold deposits in Youjiang basin area are mainly liquid inclusions which are more than 90% in all inclusions in quantity.

A series of the occurrence feature of deposit indicate that the deposit belongs to micro-disseminated gold deposit which is similar to the Muluntau type.

The present paper summarizes the typical characters of micro-disseminated gold deposits in the Luhuo rift, western Sichuan.

The genesis of the Carlin type gold deposits in the Youjiang basin, South China, has a close relationship with the evolution of the ancient oil reservoirs.

According to the geology of the Carlin type gold deposit in Youjiang district,four kinds of the fluid pass way systems are recognized:fault system,ancient structural or karst erosional unconformity,lithological conduit and the ancient carbonate platform or organic reef.

The comparison between orebodies and wall rocks of the fine disseminated gold deposits;

A new type of fine disseminated gold deposits found in Northwest Guangxi,China;

The actuality and shortage in study about mechanisms of elemental paragenesis and separation as exemplified by fine disseminated gold deposits in Southwest Guizhou Province have been reviewed in this paper.
