胶东中生代构造体制转折过程中流体演化和金的大规模成矿
Fluid evolution and large-scale gold metallogeny during Mesozoic tectonic transition in the eastern Shandong province
-
摘要: 胶东是我国最大的金矿产出集中区,依据矿床和矿点的密集程度,可分为招远-莱州-平度、蓬莱-栖霞、牟平-乳山三个成矿带,区域内金矿类型可主要分为石英脉型和蚀变岩型。高精度的单矿物 Ar-Ar、Rb-Sr 同位素及热液锆石离子探针测年研究业已证买,金成矿的时代为120±10Ma,金矿床载金矿物-黄铁矿、矿石-黄铁矿石英脉、控矿围岩-花岗岩和变质岩等及伴生脉岩的 Sr-Nd 放射性同位素研究也证明,金成矿物质具有多源性,既来自于控矿围岩-花岗岩和变质岩,又来自于幔源的岩浆岩,流体包裹体研究表明,各类金矿具有一致的成矿流体介质条件,为低盐度 H_2O-CO_2-NaCl±CH_4流体,金成矿温度、压力条件近似,主成矿温度为170~335℃,成矿压力为70~250MPa。氢氧等稳定同位素结果表明,成矿流体可能来源于与金矿床伴生的基性幔源岩浆脱水形成的岩浆水,但在地壳浅部遭受到大气降水的混合。因此,胶东各类型金矿是在同一成矿背景下形成的矿床,与区域内中生代构造体制转折作用有关,也是中生代构造体制转折的表现形式之一。
