THE GEOLOGICAL FEATURES OF THE SHIZHUYUAN SUPER-LARGE TUNGSTEN-POLYMETAL DEPOSIT ASSOCIATED WITH GREISEN-SKARN

摘要

Most tungsten deposits of the world are distributed in the circum-Pacific metallogenic belt, and 66.5% of the total explored reserves occur in our country. Furthermore, the Nanl-ing east-west structural zone accounts for 85% of the tungsten reserves of China, and the tungsten reserves in the Shizhuyuan deposit on the northern margin of the central Nanling Mountains make up 10% of the world tungsten reserves. Obviously, the Shizhuyuan deposit is outstanding and unique.
