TECTONIC DEFORMATION AND THERMAL STRESS FIELD IN QINGHAI-TIBET PLATEAU
WANG Lian-jie, CUI Jun-wen, WANG Wei
1999, 5(3): 1-7.
Abstract (165) PDF (129KB)(19)
Abstract:
The tectonic deformation in Qinghai-Tibet plateau displays strong compression, shortening and thrust in South-North direction since Cenozoic.During the compression and shortening, extensional structure is developed in Qinghai-Tibet plateau.For the purpose of understanding formation extensional struc...
CRUSTAL EXTENSION-SHORTENING OF QINGHAI-TIBET PLATEAU AND MECHANINCAL PROPERTIES IMPLICATIONS
CUI Zuo-zhou
1999, 5(3): 8-12.
Abstract (313) PDF (103KB)(9)
Abstract:
The amount of extension and shortening of the crust of the Qinghai-Tibet plateau is roughly calculated from its thickness using the method of balanced section.The results show that it has shortened about 1400km in the N-S direction and extended 25~30km in the vertical direction.Such a tremendous sho...
DISCUSSION ON CENOZOIC TECTONICS AND DYNAMICS OF ORDOS BLOCK

Abstract (354) PDF (125KB)(40)
Abstract:
The Ordos block is peripherally surrounded by fault zones and faulted basin zones of Cenozoic age.Its southwestern boundary is a compressional tectonic belt trending NW, along which left-lateral strike-slip fault zones with thrust components, such as the HaiyuanLiupanshan fault zone, and correspondi...
THE FEATURE AND FORMATION MECHANISM OF ARCIFORM THRUST-NAPPE STRUCTURE ZONE OF THE SOUTHERN NINGXIA
LI Tian-bin
1999, 5(3): 22-27.
Abstract (167) PDF (102KB)(10)
Abstract:
The southern Ningxia's arciform structure zone, extending 150~300km, consists of four great arcuate thrust-nappe structural belts with a convex toward the northeast.Every belt is composed of many thrust sheets and back margin fault basin.They formed typical basin-range structures.Since Yanshanian mo...
THERMAL HISTORY AND TECTONO-GEOMORPHIC EVOLUTION OF PANSHAN PLUTON AT SOUTHERN MARGIN OF THE YANSHAN OROGENIC BELT
WU Zhen-han, CUI Sheng-qin, ZHU Da-gang, FENG Xiang-yang
1999, 5(3): 28-32.
Abstract (349) PDF (122KB)(9)
Abstract:
The thermal history and uplifting of the Pangshan pluton at the southern margin of the Yanshan orogenic belt were studied in detail by thermochronological dating.It was revealed that the Panshan pluton was intruded at a depth of about 10km before 226.48Ma. This was followed by a rapid cooling at a r...
THE EVOLUTION OF MESO-CENOZOIC FAULT AND TIMES OF THE COMPRESSION AND EXTENSION STRUCTURE IN THE EAST YANSHAN AREA AND XIALIAOHE BASIN
MA Yin-sheng
1999, 5(3): 33-39.
Abstract (341) PDF (342KB)(10)
Abstract:
The analysis of structural evolution in the East Yanshan Area and Xialiaohe Basin since Meso-Cenozoic shows that this area has experienced five times of compression deformation (the end of Middle Triassic, Early Jurassic, Late Jurassic, Cretaceous and Paleogene) which resulted in withering or disapp...
PLIOCENE-QUATERNARY FAULTING PATTERN AND LEFT-SLIP PROPAGATION TECTONICS IN NORTH CHINA
ZHANG Yue-qiao, P. Vergely, J. L. Mercier
1999, 5(3): 40-46.
Abstract (274) PDF (139KB)(25)
Abstract:
North China includes two extensional domains:the grabens surrounding the Ordos block in the west, and Huabei-Bohai plain basins in the east.Pliocene-Quaternary faulting in grabens around the Ordos block displays predominantly normaldip slip displacements with a right-lateral or left-lateral slip com...
A EXPLANATION FOR CRUSTAL FORMATION AND CONTINENTAL SHIFT
QIAN Wei-hong
1999, 5(3): 47-52.
Abstract (350) PDF (63KB)(7)
Abstract:
The formation of the earth crust and its evolution is a key issue for geodynamics or continental dynamics.The formation of original continental plates and their split and shift are illustrated in this paper using a dynamical scenario.
ON LAYER-SLIP,DIP-SLIP AND STRIKE-SLIP FAULT SYSTEMS
SUN Yan, LI Ben-liang, LIU Hai-ling, WNAG Xing-yuan
1999, 5(3): 53-57.
Abstract (351) PDF (92KB)(21)
Abstract:
The thin-skinned layer-block structures confined by the reverse dip-slip fault in a leading edge, normal dip-slip fault in a back edge and strike-slip faults (lateral sinistral and/or dextral fault)widely developed in the middle-lower Yangtze River area, may result from layering of rock materials an...
METALLOGENIC REGULAR OF GOLD DEPOSIT IN XIAOBAN,FUJIAN,AND ITS VICINITY AND THEIR FURTHER EXPLORATION

Abstract (212) PDF (180KB)(17)
Abstract:
With more than 20 gold deposits (or gold ore spots)and favorite oreforming conditions, Xiaoban and its vicinity are a concentric area of gold deposit in middle part of Fujian.The main metallogenic and ore-controlling factors for the gold deposit in the area are a favorite assemblage of metallogenic ...
A PRELIMINARY STUDY ON THE ORE-CONTROLLED STRUCTURE IN THE XITAN GOLD MINE,XINJIANG
ZHANG Xue-ren, WANG Ping-an
1999, 5(3): 65-70.
Abstract (247) PDF (118KB)(14)
Abstract:
The Xitan gold deposit is of a quartz vein-type with little sulfides.Their locations of appearance and spatial distribution are related to the repeated activities of the Qlugemingtashi ductile shear zone and the major Kushui fault and the resulting lower order structutes.It was considered to be cont...
ENVIRONMENTAL EFFECT OF ENGINEERING ACTIVITIES OF YELLOW RIVER WATER CONSERVANCY IN ANCIENT CHINA
LI E-rong
1999, 5(3): 71-75.
Abstract (262) PDF (51KB)(6)
Abstract:
Historically in China, the engineering activities of the Yellow River water conservancy were mostly focused on the water harnessing, while the silt harnessing was neglected.As a result, the Yellow River became gradually a world-famous above-ground suspended river and a "watershed" in the middle part...
