Heilongjiang region belongs to Pa-l Asia tectonic field, which is composed of the accretion zone of Siberialandmass group and Pa-l China landmass group. T he Eerqis-i Zuolun-Heihe suture is the boundary of the two plates. The tectonic unit from Heilongjiang is subdivided into four massives and three belts, i1e. the Eerguna land mass, axing.anling orogenic belt, Xiaoxing. anling-Songnen land mass, Yichun-Zhangguangcailing orogenic belt, Bulieya-Jiamus-i Xingkai land mass, Zalantun land mass and Wandashan orogenicbelt. The attribution of ÑandÒtectonic units was rectified obviously based on the Regional Geology of Heilongj iang Province, the Ó and Ô tectonic units was also revised.
