THE RESEARCH OF THE GEOLOGICAL CHARACTERS ON THE NEWLY FOUND OREBODY IN THE DEEP OF JINCHUAN MINING AREA Ⅰ

Through the investigation on the characters of newly found orebody in the deep of Jinchuan Mining Areai.the author and his research group realized that the geological structure and hydrothermal fluid has played an important role in the formation of the rich orebody and massive orebody in the deep of Jinchuan deposit.It has been found that the mineralization and enrichment in deep reach of the Jinchuan mining area is not only related to the rock mass,but also closely associated with the spst-minerogenetic tectonic-hydrothermal fluid,the tectonic hydrothermal makes part of the primary minerogenetic materials active and reaccumulated at the low press and expanding portions of the fold or fault,and thus provides convincing evidence for seeking orebody in deep portions of the Jinchuan mining area.
