| Abstract:Source of material is one of the essential problems concerning deposits, so it will undoubtedly find its important place in the study of sulphur deposits. In this paper, based on sources of sulphureous material, a new classification of sulphur deposits is presented as follows. I. Ore deposits whose ore material derives from great depth of the earth:1. Deposits by submarine volcanism, (1) In geosynclinal areas: A. Baiyinchang type; B. Hailar type; C. Tungshengmiao type; D. Dajianping type; (2) In platform areas: Yingde type in northern Guangdong; 2. Ore deposits by subaerial volcanism, (1) Porphyrite pyrite deposits of volcanic basin type: A. Xiangshan type; B. Xinqiao type; C. Xiaoling type; D. Yuntaishan type; (2): Volcano-tectonic depression type; ( 3) Native sulphur by recent volcanism; 3. Magmatic and hydrothermal ore deposits:Ⅱ. Ore deposits whose ore material comes from the earth's surface, 1. Continental sedimentary pyritic deposits, 2. Sulphur deposits by biochemical processes: A. Native sulphur; B. Hydrogen sulphide. Sulphur deposits jn our country are generally dispersed along geosynclinal systems and deep fracture zones, which is easily to be seen. In geographical distribution, there exist two east-west striking pyrite zones, i. e. Nei MonggolDa Xinganling pyrite zone in the north and Kunlun-Qinling pyrite zone in the central China, there also exists a north-south striking pyrite zone along Xikang-Yunnan axis. As for native sulphur and hyclrogen sulphide deposits, they appear to be scattered on the Kunming-Taiwan-Heilongjiang arc along the edge of the Pacific Ocean. All this indicates not only the geographical distribution of sulphur deposits in our country but their metallogenic features as well. |
