| 中文摘要: |
| 东秦岭金、银、多金属成矿带,所处的东秦岭造山带经历了6个演化阶段,形成了一套NWW向的叠瓦式构造,成矿带位于莫氏面、居里面由浅变深的斜坡梯度带上,地球化学异常具有北西成带、北东成行、环绕岩体、相同元素组合的异常与地层分布一致等特点。宽坪群和二郎坪群为主要的含矿层位,燕山晚期花岗岩和华力西期复式花岗岩为主要成矿岩体。将东秦岭各类金属矿床分为6个成因类型,划分了6个级成矿带和12个级成矿亚带。文章还对东秦岭地区成矿规律和找矿标志进行了阐述与归纳。 |
| 英文摘要: |
| The east Qinling Au-Ag polymetal ore belt is located in the east Qinling orogenic belt where 6 evolution stages took place with a set of NWW imbricate structure. The ore belt lies at the deep-shallow gradient zone of moho and curie plane. The geochemical anomlyies generally extend in NW or NE directions or around rock bodies. The same element combination anomlies are coincided with strata. Based on the geoanomly theory Kuanping and Erlangping group and Yanshanian granite and Hercynian granitic complexes are host rocks. Au deposits in the ore belt are classified into 6 genetic types and the belt is divided into 6 Ⅲ and 12 Ⅳ sub-scale belts. And ore forming pattern and ore-searching marks are outlined. |
