Abstract:

胶东海阳郭城地区高密度、高频率产出多种脉岩类岩石,主要包括辉绿岩(βμ)、煌斑岩(χ)、闪长岩(δ)、闪长玢岩(δμ)、花岗斑岩(νπ)、正长斑岩(ξπ)等,且脉岩与金矿密切伴生。为了探讨该区脉岩的成因、源区性质及成岩构造背景,本文通过岩石学和地球化学研究表明,该区脉岩总体属于钾质钙碱性系列,高Mg、Fe、Al,低Ti,来自深部同一岩浆源区,富集LILE和LREE,相对亏损HFSE,为弥散状角闪石相橄榄岩富集地幔部分熔融作用(9.52%)的产物。成岩过程中岩浆经历了橄榄石、单斜辉石、角闪石等暗色矿物以及少量斜长石的分离结晶作用,岩浆侵位过程中没有受到地壳物质的混染。脉岩形成于大陆板内环境,同时具有大陆弧钙碱性玄武岩的地球化学特征,暗示了在构造背景上与太平洋板块的俯冲作用及晚侏罗世至早白垩世华北地块岩石圈的区域性伸展―减薄机制有关,可能与郯庐断裂带在该时期的左行走滑引张关系更为密切。
