摘要
构造地球化学障就是在构造地球化学场中元素浓度梯度极大值所在的地质构造地段.其本质是构造地球化学环境发生突变.而使元素活动性急剧降低从而发生元素构造地球化学分异和沉淀作用的地质构造地段.本文运用构造地球化学障成矿理论对丰山矿田的断裂构造地球化学障,褶皱构造地球化学障、接触带构造地球化学障及其成矿作用作了系统研究.
Tectono-geochemical obstacle is the geological structural sector in which elemental consistency gradient is maximum in tectono-geochemicail field. Essentially, it is the geological structural sector in which the elemental activity is reduced rapidly because the tectono-geochemical environment changes suddenly and results in the differentiation and precipitation of elemental tectono-geochemistry. This paper applies the metallogenic theory of tectono-geochcmical obstacle to a systematic study of the tectono-geochemical obstacles of fautls, folds, and contact zones, and their mineralizations in the Fengshan ore field.
