| 中文摘要: |
| 湖南西北部下寒武统黑色岩系蕴藏着丰富的镍钼钒多金属矿床及其伴生的Au,Ag,Pt,Pd等贵金属矿化。它是我国新类型的镍钼矿床及贵金属矿化极具找矿潜力的地区。富含有机质和黄铁矿的黑色岩系既是镍钼矿的富集层,也是贵金属矿化的主要富集层。矿床的成矿作用是伴随热水的加入而开始,热水沉积与正常沉积交替期是成矿的高峰期,至正常沉积期结束。生物及生物地球化学作用在黑色岩系的成岩成矿过程中起了重要作用。矿床以同生沉积为主,兼有热水性质沉积特点。其成因应归属于生物地球化学沉积矿床范畴。 |
| 英文摘要: |
| In black rock series of Lower Cambrian system in the northwest Hunan province occur many Ni-Mo-V poly-metal deposits associated with noble metal(Au,Ag,Pt,Pd etc.) mineralization.Such deposit is a new type of Ni-Mo deposit and the northwest Hunan province is a potential area for exploring this type of deposit.The black rock series is not only rich in organic matter and pyrite but also in Ni,Mo and noble metals.The metallogenic process began with merging of hot water.The alternating period of the hot water sedimentation and the normal sedimentation is the peak time of mineralization.The mineralization terminated at the end of the normal sedimentation.Organism and bio-geochemical process played an important role in diagenesis and mineralization of the black rock series.The deposit is formed mainly by syn-sedimentaion and coupled with hot water sedimentation and it should be belonged to the bio-geochemically sedimentary ore deposit. |
