摘要: 以甘肃北山为主,探讨了新、甘、蒙北山地区中生代构造-岩浆活动与成矿作用的主要规律与特征。认为该地区受印支期-燕山期滨西太平洋构造活动影响较大,成矿作用强烈而广泛,为一重要的成矿期。针对本区铜多金属矿勘查研究工作,提出了新的思路与建议。

Abstract: Taking Beishan region as the main studying area,the major regulations and characteristics of Mesozoic structural-magmatic activities and mineralization are discussed. It is supposed that the studying area,where mineralization occurred in tensively and widely,had been strongly influenced by geotectonic activities of offshore west Pacific Ocean in the period of Indosinian-Yanshanian which is an important mineralization period. Finally,some thoughts and suggestions for studying prospecting copper and polymetallic depositin this area have been put forward.
