摘要
在分析前人研究成果与以往地质资料基础上,结合找矿实践,将甘肃与火山岩有关铜矿分为八种类型,圈出8个找矿预测区。认为与火山岩有关的铜矿勘查不能仅局限于火山岩层或火山构造,晚期构造、岩浆热液活动与成矿作用对先期成矿的叠加、富集及矿床(体)最终定位的影响极为重要。针对新一轮找矿工作提出了具体的思路与建议。
On the bases of previous geological literatures and achievements, the copper deposits relative to volcanics in Gansu Province are divided into 8 types; copper deposits relative to volcanics are circled out. It is furthermore, 8 prospective areas for prospecting supposed that prospecting copper deposits relative to volcanics should not be confined in volcanic strata and structures only, hut the effect of late stage structures, magmatic hydro-thermal activities, and mineralization on pre-stacking, enrichment, and the final localization of deposits is of vital importance. Finally, the particular thoughts and propositions have been put forward for the newest turn of prospecting.
