A PRELIMINARY DISCUSSION ON DEPTH OF GOLD DEPOSITS IN EARLY PRECAMBRIAN METAMORPHIC ROCKS OF CHINA

The comparision of gold deposits in between greenstone belt abroad and Early preca-mbrian metamorphic rocks of China shows that the succession of strata, lithological characters of metamorphic rocks of Early Precambrian in China are comparable with those of greemstone belt abroad. The country rocks, ore controlling structures and occur-res of the gold deposits in the Early Pfecambrian metamorphic rocks are also similar to those in the greenstone belt abroad. It suggests the possibility of searching for deepseated gold deposits in areas of Early Precambrian metamorphic rocks and in old mines of China.
