摘要:桐树沟铜多金属矿产于拆离断层下盘,拆离断层沿新太古界太华群结晶基底与上覆中元古界熊耳群盖层的不整合面展布.矿体沿走向和倾向的形态、产状与破碎带密切相关,矿脉沿走向及倾向上具舒缓波状,在挤压强烈、产状突变处矿化富集,形成工业矿体.根据矿床地质特征和矿体的空间展布规律,认为沿拆离断层深部及其北东方向找矿前景看好

( College of Earth and the Physical Information ,Central South University, Changsha,Hunan, 410083, P. R. China) Abstract: Tongshugou Cu polymetallic deposit is in the footwall of the detachment faults, the detachment faults distribute with unconformity along the Archean Taihua Group crystalline basement overlying the Proterozoic Xionger group strata. The ore body is closely related to the broken belt along the strike and dip of the form, occurence and veins along the strike and the tendency has soothing undulate, the mineralization has enriched in the strong compression and in occurrence muta tion position, forming the industrial ore bodies, Considering geological characteristics of the ore deposit and the spatial dis tribution law of ore-bodies, the deep area of unconformity as well as its northeast is the prospective targets for ore-finding Key words: Cu polymetallic deposit; ore-body feature; deposit type; prospecting foreground
地质概况 1
桐树沟矿区大地构造位置位于华北地台南缘、
华台缘凹陷,晴山一鲁山拱褶断束区申部、熊耳山地体的西段.熊耳山地体南以近东西向的马超营断裂为界,北以洛宁断裂为界,西接靖山,东接外方山,是-个向洛阳盆地倾没、呈NE向展布、周边被断层和新生代地层围限的楔状地体.区内古老变质岩系发育,变质程度较深,并具强烈的混合岩化作用,矿体产于变质核杂岩的拆离断层及其附近的断裂构造中.
