晋北地区中元古代岩墙群的地球化学特征和大地构造背景
Geochemical characteristics and tectonic setting of Mesoproterozoic dyke swarmsin northern Shanxi
-
摘要: 晋北地区发育大规模的中元古代北北西向岩墙群，未变形和未变质，是华北克拉通前寒武纪构造演化研究的最显著标志，根据本区岩墙群的岩石学和地球化学研究，这些岩墙群的岩石属于板内大陆裂谷玄武岩系列，形成于大陆裂谷拉张的构造环境，与东侧的燕辽－中条拗拉槽内的火山岩岩石化学对比分析，本区岩墙群的基性岩浆可能来自拗拉槽深部，这些基性岩浆从拗拉槽的深部向北西方向侵位于晋北地区先存的构造裂隙中形成了基性岩墙群。
