摘要
本文在以往大量资料的基础上,对德尔尼铜钴矿区及外围的地质环境、控矿因素、成矿规律、矿床地质特征、找矿标志,地球物理场和地球化学场的特征,以及对以往投入的各种方法的找矿有效性作了分析,总结出德尔尼式铜钴矿床的文字描述式模型、表格式模型和图形式模型,进而建立起德尔尼铜钴矿床的地质-地球物理-地球化学模型。
The deerni copper-cobalt deposit is situated at 15 km southwest of Dawo town in Golong Tibetan Autonomous Prefecture,Qinghai Province.Ore exposure of the deposit was discovered bynative people in 1958.Afterwards,reconnassance and detail survey with geological,geochemical,geo-physical methods were conducted in succession.By the end of 1970,preliminary exploration had beencompleted and the conclution was reached that it was a large copper-cobalt deposit.Based on a lot offormerly prospecting data,metallogenic factors,ore-control law,geological characteristics of the miner-al deposit,ore guide of prospecting,features of thd geophysical and geochemical field and effectivity ofvarious prospecting means are discussed in this paper,and then,taking advantage of various style ofwriting,table and diagram,a geological-geophysical-geochemical model of the Deerni copper-cobalt de-posit is established.
