| 摘 要： | 辽宁结晶基底斜长角闪岩为贫碱低铝型斜长角闪岩,从鞍山期至辽河期斜长角闪岩基性度循序增高,主元素地球化学模型显示基底层和幔岩层之间的过渡特点。鞍山群斜长九闪岩微量元素主要分3大群;辽河群斜长角闪岩微量元素分2大群。其原岩主要为基性岩浆岩,少数为钙泥质沉积岩。该类岩石为 Ag、Co、Cu、Zn、Au 等成矿元素的主要荷载岩石。

| Abstract: | The amphibolite in crystalline basement of Liaoning is poor-alkali low-aluminium type.The basicity increases in order from Anshan age to Liaohe age. Geochemical model ofessential elements shows transitional characters between basement layer and mantal layer.Trace elements in amphibolite of Anshan Group and Liaohe Group are divided into threeand two groups respectively. The primary rock mainly is basic magmatic-rock, little iscalcareous argillaceous-sedimentary rock. This kind of amphibolite is main load rock ofmetallogenetic elements, such as Ag, Co, Cu, Zn, Au. |
