英文摘要	1.8 similar to 1.6Ga is a period when the planet Earth witnessed a critical revolution in global tectonic configuration, paleogeographic environment and biological evolution. The formation of the crystalline basement represents the end of the Paleoproterozoic, whereas the development of stable sedimentary covers represents the start of the Mesoproterozoic. The Late Paleoproterozoic (1.8 similar to 1.6Ga) is referred as the "Statherian" in the international chronostratigraphic chart, and the boundary between the Paleoproterozoic and the Mesoproterozoic is inferred at 1.6Ga by the International Commision on Stratigraphy (ICS). In the North China Craton (NCC), the "Lvliang Movement" was usually considered to be a significant tectono-thermal event marking the final generation of the crystalline basement, which was followed by the development of platform-type sedimentary covers represented by the Changcheng System. Most Chinese geologists take the deposition of the Changcheng System represents the beginning of the Mesoproterozoic in China at 1.8Ga, some 200Myr older than the age proposed by ICS. The expressions of the geological records between 1.8Ga and 1.6Ga are confusing in both domestic and international literatures. This confusion arises as there are different viewpoints; 1) The formation of the crystalline basement of the NCC or its final amalgamation is marked by "the Lvliang Movement", and the metamorphic age of the crystalline basement is no later than 1.8Ga; 2) Although many researchers believe that the bottom boundary age of the Changcheng System is 1.8Ga, the starting time of stable sedimentary cover and representative sedimentary records in the NCC vary in different region; 3) The geodynamic evolution in the NCC and its tectonic transition from basement formation to stable sedimentary cover development are controversial, besides, previous studies also lack precise geochronological constraints. In this paper, we review the progresses in the study of magmatic and sedimentary records in the NCC; especially the southern NCC from 1.8Ga to 1.6Ga, discuss the Paleo-Mesoproterozoic boundary and the division of related strata, and then address the challenging scientific issues. We suggest that, 1) the volcanic and sedimentary records during 1.8Ga to 1.6 Ga are well preserved in the southern NCC, whilst the Xiong' er Group (1.8 similar to 1.75Ga), which is older than the Changcheng Group, is the earliest sedimentary cover recorded subsequent to the formation of the crystalline basement. The Dagushi Formation is a typical fluvial-lacustrine sedimentary sequence mainly composed of sandstone and mudstone at the bottom of the Xiong' er Group. 2) There are two alternative schemes about the boundary age of the Paleo-Mesoproterozoic; one is 1.8Ga, being referred to the starting sedimentary time of the Dagushi Formation at the bottom of the Xiong' er Group; the other is 1.6Ga which moves the Gaoyuzhuang Formation from the Changcheng Group into the Jixian Group, the Dahongyu Formation and the lower formations in the Changcheng Group are classified as the Paleoproterozoic layers, and the 1.8 similar to 1.6Ga volcanic and sedimentary sequences are classified as the Late Paleoproterozoic Statherian. 3) The geological records during 1.8 similar to 1.6Ga in the NCC consist of well preserved volcanic series of the Xiong' er Group and the other volcanic and sedimentary sequences, multi-stage mafic dike swarms, anorthosite and A-type granites (including rapakivi granites).
