The characteristics of chert from micro-disseminated gold deposits and their origin significance in southwestern Guizhou, China

摘要

The southwestern Guizhou Province has been acknowledged as one of the most important and potential gold producing areas in the People's Republic of China and has attracted world-wide attention since the discovery of a series of sediment-hosted micro-disseminated gold deposits in the last twenty years. Chert widely occurs in the gold deposits, Study on geology and geochemistry of the chert may be important for a better understanding of the forming condition and process of gold.
