Abstract (831) HTML (283) PDF (46747KB)(55)
Abstract:
It has been proved that the NE-trending Longmenshan thrust belt in the eastern margin of the Qinghai-Tibet Plateau was a composite of the expansion and growth of the Mesozoic and Cenozoic foreland thrust belts. However, puzzle is remained for the unidirectional and segmented migration of earth surfa...

Abstract (702) HTML (342) PDF (17284KB)(57)
Abstract:
The Paleo-Asian and Paleo-Tethyan tectonic collages in northwest China experienced a complex ocean-continent evolution from the Nanhua period to Paleozoic era, and the continent-continent collisions in Triassic formed the basement to the formation of the intracontinental basin and mountain since the...
Multistage evolution of mantle plume and the ore-forming and ore-controlling role of mantle branch structure: A study on mineralization of the Guojiadian mantle branch structure in northwestern Jiaodong
NIU Shuyin, SUN Aiqun, CHEN Chao, ZHANG Fuxiang, ZHANG Jianzhen, WANG Fengxiang

Abstract (424) HTML (105) PDF (21882KB)(33)
Abstract:
This paper briefly introduces the establishment of metallogenic theory of mantle branch structure, the characteristics, unit division and fault structure system of mantle branch structure, as well as its mineralization. During the late Yanshanian movement, the eastern part of North China entered the...

Abstract (1959) HTML (164) PDF (35380KB)(202)
Abstract:
With the increasing dependence on external oil and gas resources, China's oil and gas exploration has expanded to deep and ultra-deep areas and discovered a number of large oil and gas fields in the central and western basins successively, such as the Tahe, Puguang, Anyue, Jingbian and Shunbei oilfi...
Accumulation model of the Sinian-Cambrian shale gas in western Hubei Province, China
ZHAI Gangyi, WANG Yufang, LIU Guoheng, LU Yongchao, HE Sheng, ZHOU Zhi, LI Juan, ZHANG Yunxiao

Abstract (1789) HTML (309) PDF (36991KB)(185)
Abstract:
Landslide disaster is a major geological problem that threatens the safety of people's life and property, and the construction and operation of towns and major projects on the Loess Plateau. Aiming at the dynamic formation mechanism of landslide on the Loess Plateau, based on a large number of inves...
Diamond in oceanic peridotites-chromitites and recycled in deep mantle
YANG Jingsui
2020, 26(5): 731-741. doi: 10.12090/j.issn.1006-6616.2020.26.05.060
Abstract (364) HTML (172) PDF (16796KB)(32)
Abstract:
Microdiamonds have been recovered from mantle rocks and associated podiform chromitites in many ophiolites across the world and, in particular, in-situ diamonds were found in ophiolitic chromitites in Southern Tibet and Northern Ural. Microdiamonds in ophiolites present a new type occurrence of diam...
Internal and external factors in continental lithosphere mantle replacement in eastern China
ZHENG Jianping
2020, 26(5): 742-758. doi: 10.12090/j.issn.1006-6616.2020.26.05.061
Abstract (587) HTML (244) PDF (17762KB)(59)
Abstract:
Cratonic continent usually has an ancient, thick and refractory lithosphere mantle. Depleted basaltic composition, low density and high rigidity make the cratonic lithosphere float above the asthenosphere enclosure and exist stably for a long time. The eastern China continent was formed through the ...
Petrogenesis and geodynamic implications of Neoproterozoic typical intermediate-felsic magmatism in the western margin of the Yangtze Block, South China
LAI Shaocong, ZHU Yu

Abstract (623) HTML (727) PDF (54799KB)(96)
Abstract:
The South China Block preserves voluminous Neoproterozoic magmatism, it is thus an ideal site for understanding the mantle nature, crustal evolution, and crust-mantle interaction during the assembly and breakup of the Rodinia supercontinent. Although the previous studies have paid more attention to ...
