摘要
恒山片麻杂岩主要分布于佳木斯隆起带南缘鸡西市恒山区、麻山区、青山及勃利县一带,与新太古界麻山岩群密切相伴,是佳木斯地块最古老的变质深成侵入岩,1:20万区调报告勃利县幅、鸡西市幅将其归为元古界柳毛组(Pt_1l)及西麻山组(Pt_1x),1:25万区调报告鸡西幅将其归为新太古代变质深成岩(Ar_3H),作者通过分析佳木斯地块最新研究成果,并利用单颗粒锆石U-Pb测年结果,将恒山片麻杂岩划为新元古代,为佳木斯地块的形成与演化提供了新的证据。
Hengshan gneissic complex mainly distributed in the southern margin of Jiamusi uplifted zone, that is Hengshan area, Mashan area, Qingshan and Boli County of Jixi City, it is associated with the Mashan Group of Neoarchean Erathem closely, the oldest metamorphic pluton rocks in the Jiamusi block. In 1：200 000 regional geological survey report of Boli County and Jixi City sheets, it was regarded as Proterozoic Erathem Liumao Group（Pt_1l） and West Mashan Group（Pt_1x）, while it was classified as Neoarchean Erathem metamorphic plutonic rocks（Ar_3H） in 1：250 000 regional geological survey report of Jixi City sheet. According to the latest research results of Jiamusi block and single particle zircon U-Pb dating results, Hengshan gneissic complex is divided into Neoproterozoic Era, which provides a new evidence for the formation and evolution of the Jiamusi block.
