| 摘 要： | 天柱金矿带至今已发现脉金、砂金矿(化)点数十处。矿带位于雪峰弧形构造西南段.地层为一套呈北东向展布的震旦纪浅变质岩系。全区为一复式构造,呈北东—南西向展布,次一级背斜、向斜发育,断裂构造更为发育.矿带遥感图象具丰富的地质构造信息,尤以线性构造更为丰富,经地质解译,矿带内的断裂构造规模增大、数量增多,提示了金矿与构造,特别是与断裂构造的关系,给金矿带的综合评价提供了新的依据.矿带受北东向构造,矿床则受北西向、北西西或东西向断裂构造控制,并与环形构造也有一定的关系.地质信息,无疑给天柱金矿带的综合评价及远景区的预测提供了新的依据.

| Abstract: | More than ten mineralization points of vein gold and sand gold have been so far found in Tianzhu gold ore zone, which is situated in southwestern part of Xuefeng arc structure and the strata of which is a light metamorphic rock system in Sinian Period spreading in the direction of North-East. The whole region,which is a double structure spreading from North-East to South-West, develops into a secondary anticline or syncline and the fault structure develops more completely.
Through geological explanation, the scale and quantity of the fault structure in the ore zone is enlarged and increased, which reveals the relations between the gold ore and the structure,especially the fault structure,and provides new evidence for synthetical evaluation of the gold ore zone.
The ore zone is controlled by the fault structure in the northeastern,west
-westnorthern and westeastern parts. The ore points and ore deposits have
definite relations with the arc structure, therefore, the geological formation will provide definite evidence for synthetical evaluation and exploitation of Tianzhu gold ore zone. |
