Prediction and Prospecting of Copper Deposits Relative to Volcanics in Gansu Province

On the bases of previous geological literatures and achievements,the copper deposits relative to volcanics in Gansu Province are divided in to 8 types;furtherm ore,8 prospective areas for prospecting copper deposits relative to volcanics are circled out.It is supposed that prospecting copper deposits relative to volcanics should not be confined in volcanic strata and structures only,but the effect of late stage structures,magmatic hydro-thermal activities,and minera lization 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 new estturn of prospecting.
