【摘要】 阿尔泰山南缘泥盆纪火山——沉积建造呈北西——南东向线型带状展布,是我国西北地区铜、金、铅锌等多金属矿产的重要成矿带之一.矿带内,铜多金属矿床赋存于下泥盆统康布铁堡组中.成矿受一定的火山——沉积建造控制,有明显层控特征.虽然各小区该地层岩性复杂多变,但大致依地理位置,从南东向北西,在三个等间距的泥盆纪火山沉积盆地中,火山沉积建造及其时代有规律地变化,说明下泥盆统康布铁堡组是一个穿时性地层单位.更多还原

【Abstract】 South Altai Devonian volcanic-sedimentary formation extends in NW-SE Linear zone,and is an important Polymetallic ore belt of Cu、Au、Pb、Zn etc.in the north west China. Copper polymetallic deposite in this belt are hosted in Kang-Bu-Tie-Bao group,Lower Devonian Series.Minetalization occured in several layers but was restricted to Volcanic-sedimentary formation, that is,being strata-bound.In different fields,the lithology is complicated and changable,but mainly from SE to NW,in the three equal-interval Devonian volcanic-sedimentary depressions, volcnic-sedimentary formation and its time change regularly,These show that Lower Devonian Kang-Bu-Tie-Bao formation is a diachronous stratigraphic unit.更多还原
