Cenozoic tectonic sedimentation and magmatism
Cenozoic tectonics and geomorphic evolution of the lower Jinsha River on the southeastern margin of the Tibetan Plateau
WANG An, WANG Guocan, WANG Tuanle, SHI Yan, WEI Jie, LI Haoruo, LYU Ganyu

Abstract (1545) HTML (347) PDF (2410KB)(313) [Cited by] (1)
Abstract:

The southeastern margin of the Tibetan Plateau is distinguished by a vast transition zone with hundreds of thousands of square kilometers of low-relief surfaces, which provides an ideal window for unraveling the timing, process, and mechanisms of the tectonic propagation and surface uplift. In order...

Stratigraphic sequence characteristics and geochronology research progress of the Cenozoic in the arcuate tectonic belt on the northeastern margin of the Tibet Plateau

2023, 29(4): 465-484. doi: 10.12090/j.issn.1006-6616.2023048
Abstract (1079) HTML (246) PDF (5289KB)(192) [Cited by] (8)
Abstract:

The Cenozoic tectonic deformation and sedimentary processes in the arcuate tectonic belt along the northeastern margin of the Tibetan Plateau have been influenced by the remote effect of the subduction of the Pacific Plate as well as controlled by the northeastward extension of the Tibetan Plateau. ...

The initial time of the Fen–Wei graben system: Constraints from geochronology of the Qifeng granite porphyry dikes in the Zhongtiaoshan Mountains
CUI Jiawei, LI Zhenhong, JING Xianghui, KOU Linlin
2023, 29(4): 485-496. doi: 10.12090/j.issn.1006-6616.2023039
Abstract (1088) HTML (172) PDF (3722KB)(110) [Cited by] (3)
Abstract:

The Fen–Wei graben system is an essential Cenozoic extensional fault–depression belt in the central part of the North China craton. Previous research achievements mainly focused on its formation process and dynamic mechanism, but the initial time has been unresolved due to the lack of quantitative d...

Late Pleistocene stratigraphic sequence and geologic significance of the Kaolao Tableland in the Yuncheng Basin
NAN Debin, LI Zhenhong, DONG Xiaopeng, KOU Linlin, WEI Lijie
2023, 29(4): 497-511. doi: 10.12090/j.issn.1006-6616.2023042
Abstract (825) HTML (284) PDF (3627KB)(81) [Cited by] (2)
Abstract:

The ancient Fen River diversion was a crucial earth's surface transformation in the Yuncheng Basin during the Cenozoic. The time frame for the diversion of the ancient Fen River is still characterized by two views: the middle Pleistocene and the late Pleistocene, which has yet to be finalized. This ...

40Ar/39Ar ages of Quaternary volcanic rocks from the midwest of the Leizhou Peninsula, and their geologic significance
LI Xiang, ZHANG Zongyan, LI Haiyong, ZHANG Jianyu, BAI Xiujuan
2023, 29(4): 512-521. doi: 10.12090/j.issn.1006-6616.2023098
Abstract (779) HTML (199) PDF (1434KB)(80) [Cited by] (3)
Abstract:

Quaternary volcanic rocks are widely distributed in the Leizhou Peninsula, but the age of volcanic formation remains controversial. This study used the high-precision laser stepwise heating 40Ar/39Ar method to date the age of volcanic samples from the midwest of the Leizhou Peninsula, and two volcan...

Cenozoic climate and environment
Reconstruction of climatic and environmental evolution in the Yinchuan Basin from MIS6 to MIS5 based on spore–pollen evidence
XU Keke, BI Zhiwei, YANG Huifeng, YANG Zhenjing, NING Kai, DAI Huimin, LIU Kai, LIU Guodong
2023, 29(4): 522-542. doi: 10.12090/j.issn.1006-6616.2023091
Abstract (780) HTML (271) PDF (3411KB)(90) [Cited by] (1)
Abstract:

MIS6 to MIS5 is a typical transition period from glacial to interglacial periods. The climate elements of MIS5 are similar to that of the current warm period, and studying its evolution process can better understand the climate change process of the current warm period and the future climate change ...

The spore-pollen assemblages of the Miocene Baode Formation from Borehole ZK301 in the Yuncheng Basin and its geological significance
FAN Ruyi, YANG Mengmeng, ZHOU Junpeng, ZHAO Jianxin
2023, 29(4): 543-554. doi: 10.12090/j.issn.1006-6616.2023053
Abstract (750) HTML (198) PDF (1949KB)(90) [Cited by] (2)
Abstract:

The deposition period of the Baode Formation in the Miocene was crucial when the uplift and expansion of the Tibetan Plateau in the NE direction affected the Cenozoic basins around the Ordos Plateau. Previous research has mainly focused on tectonic and sedimentary aspects, with relatively few result...

Characteristics and geological significance of the palynological assemblages of the Qingshuiying Formation in the Beilianchi section, northeastern margin of the Tibetan Plateau
MA Jie, XIE Fei, SHI Baoyin, WANG Zhiwen, WANG Dan, DU Penglong, WANG Haibo, YUN Wenqiang, ZHANG Wenjian
2023, 29(4): 555-568. doi: 10.12090/j.issn.1006-6616.2023012
Abstract (747) HTML (138) PDF (2781KB)(63) [Cited by] (1)
Abstract:

The uplift of the Tibetan Plateau is one of the most important geological events in the Cenozoic era, which has had a far-reaching impact on climate change in neighboring regions and even the world. Scholars have already considered that the uplift of this period has a good coupling with the warm and...

Transgression–regression processes since the MIS 3 in the coastal zone of Quanzhou Bay, Fujian
ZHAO Hongmei, MAO Xin, LIU Chunlei, LI Yasong, LIU Linjing
2023, 29(4): 569-583. doi: 10.12090/j.issn.1006-6616.2023046
Abstract (627) HTML (237) PDF (1373KB)(73)
Abstract:

The coastal zone is sensitive to sea–land interaction, making it an ideal place to study the transgression–regression process in Quaternary coastal areas. Based on the stratigraphic and lithologic characteristics of two Quaternary drill cores (DZ01 and DZ02) in the coastal zone of Quanzhou Bay, Fuji...

Neogene spore-pollen assemblages and paleovegetation succession of Borehole ZKA02 in Beihai, Guangxi
YANG Wenqiang, JIA Xiaohui, WANG Zhihong, LEI Yong

Abstract:

The history of vegetation and climate change during the Cenozoic has been reconstructed by systematically analyzing the sporopollen assemblage from Borehole ZKA02 in Beihai, Guangxi. Through the analysis of spore-pollen data, four sporopollen assemblages can be recognized. From the Early Miocene to ...
