| 1 | Interactions of Copper, Evaporite, and Organic Matter and Genesis of Sandstone-Hosted Copper Deposits in the Chuxiong Basin, Yunnan Province显示文摘Studies on organic geochemistry indicate that the origin, type and maturity of organic matter are different among coal-bearing, copper-bearing and evaporite formations in the Mesozoic continental Chuxiong Basin, Yunnan, China. A mechanism has been proposed that (1) during the diagenetic mineralization stage the short-chain organic acids dervied from kerogen played an important role in remobilizing copper from source beds, while oils acted as important carrier of copper, and that (2) during the transformation or remolding mineralization stage, meteoric water leached the evaporite layers and formed downward-percolating oxidizing SO42-rich fluids; meanwhile, the copper-bearing fluids migrating upwards along growth faults from the basement was contaminated by the coal-bearing series on the way and formed reducing organic-rich fluids; oxidation-reduction occurred and sulfides formed when the two kinds of fluids met within sandstones. | Zhuang Hanping, Institute of Geochemistry, Chinese Academy of Sciences, Guiyang, GuizhouRan Chongying, He Mingqin, Geology Department, Kunming Institute of Technology, Kunming, Yunnanand Lu Jialan Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, Guangdong | 1996 | Acta Geologica Sinica(English Edition)1996，70，4： | 5 |
| 2 | Chemical composition of the ore and occurrence state of the elements in Jingbaoshan platinum-palladium deposit显示文摘The Jingbaoshan platinum-palladium deposit is China’s largest independent PGM (platinum-group met- als) deposit so far discovered. There are eleven kinds of useful components in the ore: Pt, Pd, Os, Ir, Ru, Rh, Au, Ag, Cu, Ni, and Co. The platinum-group elements, gold and silver occur in the form of minerals in ores. twenty-five kinds of precious metal minerals have been found, of which twenty one belong to the platinum-group minerals. The minerals are very small in grain size. Copper occurs mainly as copper sulfide with a small amount of free copper oxide, and the beneficiated copper accounts for 95.21%. Nickel occurs mainly as nickel sulfide, and some nickel silicate and nickel oxide occur in the ore. The beneficiated nickel accounts for 72.03%. Cobalt occurs mainly as co- balt sulfide, and there are some cobalt oxide and other kinds of cobalt. The beneficiated cobalt accounts for 77.58%. | SONG Huanbin HE Mingqin ZHANG Shangzhong YI Fenghuang | 2008 | Chinese Journal Of Geochemistry2008，27，1： | 3 |
