摘要
以华北克拉通中部的吕梁山古裂谷带为研究对象,通过详细的野外地质和镜下研究,阐述了吕梁群和野鸡山群形成于陆内拉张环境。对界河口群和吕梁群中的变质花岗岩作了超单元的杂岩划分,厘定了吕梁群为古元古代时期的产物,并探讨了铁矿成矿作用受原始成分和变质作用的制约。
The paper studied paleo-rift evolution of Lüliang Mountain,by field and microscope study,a conclusion is expounded that Lüliang formation and Yejishan formation formed under continent split environment.At the same time,the extra-unit of meta-granite complex rocks was peeled off from the Jiehekou formation and Lüliang formation.The Lüliang formation was confirmed to be belonged to Paleo-proterozoic.The bearing iron deposit derived from original layer was subjected to a metamorphosed constraint.
