原创《青海省大场地区造山型铜钼矿床潜力分析》：这是一篇与矿床论文范文相关的免费优秀学术论文范文资料,为你的论文写作提供参考。
摘 要：造山过程中会引起金、银、铜、铅锌、钼等成矿元素发生一定程度的活化、迁移和富集矿化.形成造山型矿床—以金矿床在表层,银、铜、铅锌、钼等矿床在深部或金与银、铜、铅锌、钼等成矿元素伴生的金多金属矿床.大场地区的大场、加给陇洼等金矿床均属于造山型金矿床,但未发现银、铜、铅锌、钼矿床的伴生,该区地球化学特征显示：元素组合以金砷锑为主；说明该区剥蚀作用较弱,研究该区各成矿元素地球化学图发现,铜钼两种元素在该区呈高背景,为造山作用引起.通过降低铜钼的异常下限,圈出一些铜钼异常,根据这些异常结合已有成矿事实、地质构造,圈定出两处隐伏矿预测区,预测区内发现弱化探异常与弱物探异常套合较好,在预测区内寻找造山型铜钼矿床的潜力较大.

Potential analysis of orogenic-type copper-molybdenum deposits in Dachang area, Qinghai Province
Yue Tao1, Wang Cheng Yong
Abstract： During the orogenic process, gold, silver, copper, lead and zinc, molybdenum and other ore-forming elements have been activated, migrated and enriched to a certain extent. Formation of orogenic-type Deposits - gold deposits in the surface layer of silver, copper, lead and zinc, molybdenum and other deposits in the deep or gold and silver, copper, lead and zinc, molybdenum and other metallogenic elements associated with gold polymetallic deposits. Dachang area, in addition to the long depression of Dachang gold deposit belong to orogenic-type gold deposits, but no silver, copper, lead and zinc, molybdenum deposit, according to the elements for gold and arsenic antimony； it shows that the weaker denudation, the area of each metallogenic element geochemical map, two elements of copper Mo was high background in the area, due to orogenesis. The abnormal lower limit of copper and molybdenum, copper and molybdenum circle some abnormal, according to these anomalies with existing metallogenic facts, geological structure delineated two area prediction of concealed ore prediction area found weakening geochemical anomaly and weak geophysical anomaly fit better, in predicting area for orogenic-type copper molybdenum ore bed potential.
Key words： orogenic-type deposit； Dachang zone； orogenic-type gold deposit； orogenic-type Copper-Molybdenum deposit
大場、加给陇洼等造山型金矿位于青海省北巴颜喀拉山脉北坡西段,行政区划属青海省玉树州曲麻莱县麻多乡管辖,其地理坐标为东经96°07′～96°20′,北纬35°15′～35°25′[1].该区已有很多专家对区内的金的成矿作用、流体包裹体及成因类型等方面做了大量的研究,取得了丰硕的成果.（本文在前人研究的基础上,通过《青海省东昆仑中段1∶5万矿调多元地质信息集成与找矿预测》项目对该区进行综合研究和成矿预测.
1.造山型矿床及其成矿模式
据研究,造山型金矿是变质地体中受构造控制的脉状后生金矿床,在时间和空间上与增生造山作用有关.造山型金矿的概念包括了过去有些文献中常见的石英脉型、韧性剪切带型、构造蚀变岩型以及一些网脉状的金矿床.它们主要形成于中地壳的绿片岩相环境,有些文献中也常称为中温或中深成热液矿床.但是,造山型金矿床形成过程中不光只有金砷锑元素的迁移；与金元素地球化学行为相似的银、铜、铅锌、钼等成矿元素也发生一定程度的活化、迁移和富集矿化[2].形成造山型矿床—以金矿床在表层,银、铜、铅锌、钼等矿床在深部或金与银、铜、铅锌、钼等成矿元素伴生的金多金属矿床.例如,河南栾川康山金银铅矿床,河南灵宝大湖金钼矿床（上部为金矿,下部为钼矿）,内蒙古白乃庙铜（-金-钼）矿床和白乃庙金（-铜）矿床,等等[2].
