Abstract
AbstractIt is a long-term objective for Chinese geologists to make the Meso-Neoproterozoic strata in North China Craton (NCC) the international reference section of the Late Precambrian chronostratigraphic stratigraphy. However, the establishment of highly precise and reliable Precambrian chronostratigraphic frame would be a top priority in current chronostratigraphic study and also a basis for Precambrian stratigraphic correlation and tectonic interpretation in each continent of the globe. This chapter will be focused on the achievements of the Chinese Meso-Neoproterozoic chronostratigraphy, especially for the new calibration of Meso-Neoproterozoic stratigraphic division in North China Craton (NCC) as well as for the new isotopic dating of Neoproterozoic chronostratigraphy in Yangtze Craton (YC in southern China) and Tarim Block (northwest China). Those new isotopic dating data would result in a complete change in the Meso-Neoproterozoic chronostratigraphic calibration, division and correlation among above three regions, and update the regional geological cognition and the metallogenic mechanism interpretation. In recent years, the Meso-Neoproterozoic petroleum geological study and exploration put forward the precise chronostratigraphic division and correlation of sedimentary cover and crystalline basement of the petroliferous basins. In view of the achievements in the chronostratigraphic isotopic technique, it is possible to obtain the complete data of precise and reliable isotopic dating for Precambrian cover and basement in NCC, YC and Tarim Block (TB), so that more complete Meso-Neoproterozoic isotopic chronostratigraphic data would be available for the vest number of geologists in this chapter.KeywordsMeso-Neoproterozoicchronostratigraphic frameNorth China craton (NCC)Yangtze craton (YC)Tarim block (TB)
