Stratigraphy of Upper Cretaceous──Paleogene deposits of northwestern Zeya──Burya sedimentary basin

引用

Global Geology 2007年第2期10卷 130-147页

作者： t.V. kezina N.D. Litvinenko Amur State University Blagoveshchensk 675027 Russia Central Laboratory Dal'geologiya Khabarovsk 680000 Russia

In the northwestern Zeya──Bureya sedimentary basin, the authors studied coal deposits, including Ivanovsko-Erkovetskyu brown coal square on which is worked off largest Erkovetsky field of brown coal, extending to south flank of the Mesozoic──Cenozoic Belogor'e depression. the verified stratigraphic scheme of the coalfield sedimentary sequence is substantiated by palynological data on core samples from 18 boreholes sampled in the course of detailed prospecting and by paleobotanical analysis of sections in the Yuzhnyi sector of the coalfield. Sections of the Erkovtsy, Arkhara Boguchan, and Raichikha brown-coal mines are correlated. Stratigraphic subdivisions distinguished in the studied sedimentary succession are the middle and upper tsagayan subformations (the latter incorporating the Kivda Beds), Raichikha and Mukhino formations.

An international cooperative study of the Late Cretaceous biota and non-marine strata including the Cretaceous-Paleogene(K--Pg) boundary in Jiayin near the Heilongjiang River,China during 2002-2010,is summarized in this paper. the strata includes the Upper Cretaceous Yong'ancun-,taipinglinchang-,Yuliang-zi-,and Furao formations,and the Paleocence Wuyun Formation consisting of Baoshantou Member and a Coalbearing Member. Seven palynological assemblages from Santonian to Paleocene are recognized,which is used for definition of the K--Pg boundary. through the palynological analysis of three drilled boreholes (XHY-2005,2006,2008) in Xiaoheyan of western Jiayin,the K--Pg boundary is defined within 20. 00-20. 05 m in the borehole XHY-2006 (as a standard boundary) which is just between the top of Furao Formation (late Maasterichtian) and the base of Baishantou Member (early Danian) . these new research results are supported by paleo- magnetic,geochemical and other analyses,also. On the other hand,the presence of eight taxa of Maasterichtian dinosaurs (mostly hadrosaurids) have been recognized by the authors; and two mega-plant assemblages from the Yong'ancun Fm (Santonian) to taipinglinchang Fm (Campanian) are confirmed. these research a-chievements indicate that the Upper Cretaceous-Paleocene in Jiayin can be well correlated to the strata in the neighboring Zeya-Bureja basin,Russia. the K--Pg boundary definited in Jiayin is the first well documented non-marine K--Pg boundary in China. Also the related paleoclimate,paleoenvironment and the mass extinctions in this area during the Cretaceous-Paleocene transition are also discussed.
