| 摘 要： | 本文简要回顾了干沙鄂博稀土矿的发现与勘查历程;认为海西晚期碱性斑岩体的侵入及其以萤石化、碳酸盐化、硅化、重晶石化为主的面型蚀变,放射性异常和La、Ce为主的化探异常是矿区的主要找矿标志;通过以碱性斑岩体的产出面积、矿化深度、含矿率等为主的预测标志的定性预测,认为矿区具有大型稀土型矿床成矿前景;从地质、地球化学、重砂异常综合信息的初步分析,矿区外围具有稀土及多金属矿的勘查前景。

| Abstract: | Sansuoma gold deposit of Xiahe County is located in the west Hercynian -Indosinian fault-fold belt of Qinling Mountain and copper, gold, silver, antimony, molybdenum metallogenic belt of Xiehe-Hezuo. The ore body existed within the biotite diorite contact belt of Sansuoma, controlled by faults structure. Based on the study of previous work and recent survey result, the paper summarized the geological background, ore body characteristics and prospecting marks. |
