英文摘要The khondalite series, located in the western part of the North China Craton (NCC), is one of the most significant objects that are essential for understanding formation and evolution of the NCC. To date, a great number of researches suggested that the khondalite series, a suite of high-grade metamorphic alumina-rich sedimentary rocks, had witnessed two important metamorphic events during 1.95 similar to 1.82Ga, including high pressure/high temperature metamorphism and high to unltra-high temperature/medium to low pressure metamorphism. The available data from drilling samples of the Mesozoic-Cenozoic Ordos Basin revealed that its basement rocks were similar with the khondalite series in petrology, provenance, depositional age and metamorphic timing. It appears that a larger part of the Ordos Block had been covered by the protolithes of the khondalite series and been involved by the subsequent high-grade metamorphic events. However, the debates on the distribution, isochronism and depositional environment of the protolithes of the khondalite series are still ongoing. These points are invaluable for constraining temporal-spatial distribution of the khondalite series and understanding tectonic evolution of the western NCC. As an attempt to facilitate deciphering the protolith basin, three typical sections of the khondalite series in the Helanshan, Daqingshan and Jining areas were chosen for deposition sequence subdivisions, stratigraphic correlation and lithofacies paleogeographic rebuilding. These results in this paper suggest that: (1) the khondalite series in the northern margin of the Ordos Block are composed of three correlatable deposition sequences; (2) an epeiric sea over the Ordos Block (Ordos Epeiric Sea) might be responsible for the planar distribution of the khondalite series and its transgressive direction was mainly from the Helanshan-interior of the block to the Daqingshan and Jining areas; and (3) the Ordos Epeiric Sea induced accumulation was completed during the inactive period (2.5 similar to 2.3Ga) and the khondalite series might be the first sedimentary cover after the cratonization of the NCC.
