摘　　要：黑龙江省受古亚洲洋、蒙古—鄂霍茨克洋和环太平洋构造体系影响及叠合改造,地质演化历史复杂,作为其重要演化记录的地层一直是研究的重点,并且近年来获得了一批高精度年代学数据和古生物方面的资料。本文基于近30年黑龙江省的区域地层研究成果,结合前人资料,梳理和总结了20世纪《黑龙江省区域地质志》出版后前新生代地层研究的新进展,初步确定了前寒武纪地层主要为中—新元古界的划分对比方案,将传统作为地块基底的部分前寒武系厘定为古生界,就部分古生代地层时代做了修正,提出了中生界划分对比新方案。另外,将一些造山带非史密斯地层厘定为俯冲增生杂岩,并就其物质组成的基质和岩块进行了总结,进而为区域地层划分对比和地质构造演化提供黑龙江省地层方面的资料。Due to influence by superimposed tectonics of Paleo-Asian Ocean,Mongolian-Okhotsk and Pacific rim tectonic systems,the geological evolution history of Heilongjiang Province is complex.As an important material record,the strata have always been the focus of research.In recent years,a number of high-precision chronological data have been obtained.This article,based on the research results of regional stratigraphy in Heilongjiang Province in the past 30 years,combined with previous data,summarizes the new progress in the study of the pre-Cenozoic strata after“Regional Geology of Heilongjiang Province”publication in the last century,including that the Precambrian strata are mainly composed of the Meso-and Neoproterozoic rocks,part of the traditionally Precambrian crystalline base is defined as the Paleozoic,ages of some Paleozoic strata have been modified,new division and correlation scheme of Mesozoic is put forward.In addition,some of the non-Smith strata in the orogenic belt are determined to be subduction accretion complex,and the matrix and rock block of its material composition are summarized.The present summary provides the stratigraphic data of Heilongjiang Province for regional stratigraphic division and correlation,and geological structure evolution as well.
