摘要
以板块理论为指导,对黑龙江省区域大地构造单元进行了划分,提出黑龙江省属古亚洲构造域,由亲西伯利亚陆块群和古中华陆块群两大板块的增生带组成。额尔齐斯—佐伦—黑河缝合线为两大板块的分界线,并进一步划分为4块3带,即额尔古纳地块、大兴安岭造山带;小兴安岭—松嫩地块、伊春—张广才岭造山带;布列亚—佳木斯—兴凯地块、扎兰屯地块和完达山造山带。在黑龙江省区域地质志的基础上,对Ⅰ、Ⅱ级大地构造单元的归属做了较大调整,对Ⅲ、Ⅳ级构造单元部分做了修正。
According to the basic geologiy of Heilongjiang Province, the authors clarified the geotectonic unit of Heilongjiang provincial region with the guidance of plate theory. Heilongjiang region belongs to Pal-Asia tectonic field, which is composed of the accretion zone of Siberia landmass group and Pal-China landmass group. The Eerqisi - Zuolun - Heihe suture is the boundary of the two plates. The tectonic unit from Heilongjiang is subdivided into four massives and three belts, i.e. the Eerguna land mass, Daxing＇anling orogenic belt, Xiaoxing＇ anling - Songnen land mass, Yichun - Zhangguangcailing orogenic belt, Bulieya - Jiamusi - Xingkai land mass, Zalantun land mass and Wandashan orogenic belt. The attribution of Ⅰ and Ⅱ tectonic units was rectified obviously based on the Regional Geology of Heilongjiang Province, the Ⅲ and Ⅳ tectonic units was also revised.
