摘要
栾川老定沟钼矿床位于华北地台南缘与秦岭褶皱系接合部位。在成矿地质背景基础上,对矿床地质特征进行了研究,认为矿体形态、产状受花岗斑岩岩体形态、围岩岩性、构造控制较为明显,分布范围、产状与钙硅酸角岩、矽卡岩的分布范围、产状相一致;通过对矿床成因的初步分析,说明老定沟钼矿床无论在空间上、时间上、成因上均与深部花岗岩浆有关,同时指出了找矿标志,对以后的找矿工作有一定的指导意义。
Laodinggou molybdenum deposit is located in the ditch between the southern margin of the North China and the Qinling fold system of the eastern section. Based on the geological background, the geological characteris- tics were studied. The results show that the ore body form and occurrence were controlled obviously by the granite porphyry rock mass form, shape, rock lithology, structure control. Its distribution, occurrence was consistent with that of calcium silicate hornfels, skarn; through the genesis of the preliminary analysis, it is indicated that the old ditch molybdenum deposit given in terms of space, time, cause and deep on both granitic magma related orebody , rock distribution and thermal metamorphic belt consistency, fully illustrated mineralization emplaced in the time and space very closely. Also the prospecting has a certain significance for further exploration.
