| 摘 要： | 依据小秦岭金矿田的地质构造穿插关系和同位素年龄资料，建立了本区构造、岩浆、成矿事件序列。在此基础上，将小秦岭地区的构造演化划分为６个阶段：褶皱变质、韧性剪切变形、稳定升降、韧－脆性断裂转化、断裂活动、抬升剥蚀阶段。对小秦岭金矿田的成矿时代，成矿深度、矿床成因等地质问题，给出了构造地质学方面的判据。

| Abstract: | According to the penetrating relations of the geologic structure and the ages of the isotopes in the Xiaoqinling gold field, the succession of tectonic, magmatic and metallogenic events is established. On this basis, the tectonic evolution in the region can be divided into six stages, namely, fold matamorphic, ductile shear deformed, stable elevation, ductile brittle fractures transformed, fault activity and elevation denude stage. Aiming at the metallogenic epoch, metallogenic depth and the genesis of the deposit in Xiaoqinling gold field, the evidence of tectonic geology is given out. |
