摘要
新土沟地区下寒武统黑色岩系分布广泛,蕴含着丰富的矿产资源,其中镍钼矿资源尤为丰富。镍钼矿体赋存于下寒武统牛蹄塘组的黑色炭质黏土岩中,镍含量2.68%～7.30%,平均品位4.12%;钼含量4.80%～8.67%,平均品位6.81%。矿石主要类型为黄铁矿型镍、钼矿和炭质泥岩型镍、钼矿。通过对成矿物质来源、成矿作用的研究,初步认为新土沟镍钼矿为海相化学及生物化学沉积生成,矿床成因应为海底喷流沉积成因。
The Xintugou area the lower Cambrian black is widely distributed contains rich mineral re- sources, including Ni-Mo resources particularly rich. Ni - Mo ore bodies occur in the lower Cambrian cat- tle shoe pond group of black charcoal clay rock, Ni 2.68% - 7.30% （ mean 4. 12% ） , Mo 4.80% - 8.67% （mean 6.81% ）. Ore major types of carbonaceous mudstone type nickel, molybdenum, nickel, molybdenum pyrite type. Through the source of ore-forming materials, organic geochemical action re- search, preliminary that Xintugou nickel molybdenum for marine chemistry and biochemistry sedimentary formation, deposit origin should be bottom spray deposition.
