| 摘 要： | 托斯巴斯陶闪长岩体位于东噶尔北缘老山口铁铜金矿区内.岩石化学成分均富碱ω(Na2O+K2O)=6.68%~9.57%,高钾,大多数样品K2O/Na2O=1.12~1.31,富集Ba,Sr,Th,U,Pb等大离子亲石元素和轻稀土元素,亏损Nb,Ta,P和Ti,Eu异常不明显(δEu=0.87~1.09),显示准铝质钾玄质碱性系列岩石特征.母岩浆来源于受钾质流体交代的幔源基性岩浆与花岗质岩浆混合物,演化过程中经角闪石与辉石分离结晶作用,其形成与板块俯冲作用有关,并对老山口铁铜金矿的形成具一定贡献. |

| Abstract: | Tuosibasitao diorite,which is located in Laoshankou iron-copper-gold ore deposit field,the northern margin of Junggar,Xinjiang,intruded in early carboniferous.The diorites show that the content of SiO2 is from 51.8% to 55.5%,Na2O+K2O from 6.68% to 9.57%,and K2O/Na2O from 1.12 to 1.31,which belongs to metaluminous shoshinitic series.They display high concentrations of Ba and Sr,low concentrations of Y and Yb,noticeable negative anomaly of Nb,Ta,P and Ti,and positive anomaly of LREE,Th,U and Pb,and little abn... |
