摘要
塔东片麻岩位于吉黑两省交界处的塔东—扶育站一带,是细粒花岗闪长岩经区域变质作用而形成的变质深成侵入体,呈孤岛状残存于后期侵入岩中,经构造作用拼贴于佳木斯地块南部陆缘活动带。本文以详实的资料介绍了该片麻岩的地质特征、岩石学特征、岩石化学和地球化学特征,并探讨了其地质意义。
Tadong gneiss is located in the Tadong-Fuyu Station area, the junction of Jilin and Heilongjiang Provinces, is metamorphic plutonic intrusions formed by fine-grained granodiorite in regional metamorphism, like an island remnants in the late intrusive rocks, through tectonic action, collage on the southern margin active belt of the Jiamusi block. In this paper, the authors detailed introduced the geological, petrology, petrochemistry and geochemistry features of the gneiss, and discussed its geological significance.
