AN ANALYSIS OF PRESENT-DAY REGIONAL TECTONIC STRESS FIELD AND CRUSTAL MOVEMENT TREND IN CHINA
Sun Ye, Tan Chengxuan
1995, 1(3): 1-12.
Abstract (418) PDF (884KB)(58)
Abstract:
Tectonic stress field is here extended to cover, in addition, crustal defromation field, fault displacement field, deep crustal structures, as well as the factors that may have some influence on the stress field such as structural conditions, geophysical and geochemical conditions and properties of ...
MESOZOIC TECTONIC STRESS FIELD IN THE YANSHAN MOUNTAIN REGION, WEST OF BEIJING
Shen Shumin, Feng Xiangyany
1995, 1(3): 13-22.
Abstract (276) PDF (773KB)(35)
Abstract:
The present landscape of the Yanshan mountainous region was sculptured from rocks that had been formed and deformed during the past long geologic period of time.The region, as characterized by the sedimentary formations and structures had undergone rather weak tectonic movement from middle-late Prot...
A NOTE ON THE COMPILATION OF MAP OF CRUSTAL STABILITY ZONATION IN CHINA
Li Xiao, Yi Mingchu, Wang Lianqing, Qiao Zijing
1995, 1(3): 23-29.
Abstract (262) PDF (486KB)(35)
Abstract:
Following the idea of "Safety Island" the crustal stability zonation map of China (1:5000000)is first compiled on a grid basis in different steps using fuzzy synthetic judgement, image recognition and an expert appraisal system.
A strong earthquake and another moderately strong shock have recently be...
COUNTERCLOCKWISE ROTATION OF SOUTH CHINA BLOCK EAST OF THE TAN-LU FAULT ZONE
Xing Lisheng, Li Zhongjian, Wang Xiaofeng, Chen Bailin, Zhang Qing, Chen Xuanhua
1995, 1(3): 31-37.
Abstract (292) PDF (481KB)(19)
Abstract:
A paleomagnetic study of the tectonic deformation undergone by the middle Triassic to early Cretaceous rocks from Laiyang, Liuan, Lujiang-Zongyang and Huaining basins, on both sides of the Tan-Lu fault zone since Mesozoic was carried out.Most of the directions of isolated characteristic magnetizatio...
A NEW VIEWPOINT ON THE EVOLUTION STAGES OF QINLING OROGENIC BELT
Yang Zhihua, Su Shengrui
1995, 1(3): 38-45.
Abstract (392) PDF (619KB)(33)
Abstract:
The development and evolution of Qinling-Dabie orogenic belt is quite similar to the formation and splitting of the Pangea since Phanerozoic eon.The China paleo-plates splitted into North China and Yangtze paleo-plates and Qinling limited ocean basin in middleOrdovician Epoch.The North China and Yan...
NEW EVIDENCE FOR CORRELATION BETWEEN GLOBAL TECTONIC MOVEMENT AND EARTH'S ROTATION
Wu Zhenhan
1995, 1(3): 46-54.
Abstract (172) PDF (620KB)(32)
Abstract:
In the last 20 years, scientists in different fields have observed and studied the horizontal motion of the diffferent layers of the earth, including the hydrosphere, lithosphere, asthenosphere, lower mantle, core-mantle boundarylayer and outer core resorting to different means and methds.The veloci...
KINEMATIC VORTICITY, POLAR MOHR CIRCLE AND THIER APPLICATION IN QUANTITATIVE ANALYSIS OF GENERAL SHEAR ZONES
Zhang Jinjiang, Zheng Yadong
1995, 1(3): 55-64.
Abstract (253) PDF (605KB)(40)
Abstract:
Most of shear zones in nature are results of co-actions of simple and pure shears and called general shear zones.A general shear zone can be narrowed or broadened. The relationship between simple and pure shears, and the change of shear zones in thickness can be analysed quantitatively by the method...
NOTE ON SHUIYU COMPOUNDING VORTEX STRUCTURE IN WEST MOUNTAINS, BEIJING
Du Zitu, Li Dongxu, Gao Dezhen
1995, 1(3): 65-71.
Abstract (208) PDF (488KB)(24)
Abstract:
There are three arcuate faults that surround Shuiyu in the form of a turbine in the West Mountains, Beijing, forming a vortex structure. These faults are characteristic of compresso-shear structural planes, and their arrangement indicates a counterclockwise rotation of the outer side relative to the...
ON FEATURES OF THE MAJOR TECTONIC BELTS OF THE SHANCHENG POLYMETALLIC ORE-FORMING AREA, JIANGXI PROVINCE AND THEIR CONTROL OF ROCKS AND MINERALS
Zhu Dagang, Liu Xun
1995, 1(3): 72-81.
Abstract (303) PDF (700KB)(16)
Abstract:
A study of the major tectonic belts in the Shancheng polymetallic ore-forming area has been made mainly by an analysis of the structural features, the tectonite, the deformation and phase changes of the minerals and rocks, the tectonogeochemistry, the X-ray petrofabrics and the dynamics.The basic fe...
EVOLUTION OF THE ORE-CONTROLLING STRUCTURES OF ERDAODIANZI GOLD-DEPOSIT IN JILIN PROVINCE
Wang Yiqing, Lu Jiansheng, Yang Yanchen, Li Bile, Gao You
1995, 1(3): 82-88.
Abstract (539) PDF (509KB)(31)
Abstract:
In this paper, a further study of the structures controlling the Erdaodianzi Golddeposit was conducted.The three arcuaete structural belts that compose the Erdaodianzi brush structure are considered as the major structures that controlled the gold-deposits.The general distribution of the gold deposi...
THE ORIGIN AND DEVELOPMENT OF THOUGHT OF BIOMIGRATION
Xu Bingchuan
1995, 1(3): 89-96.
Abstract (283) PDF (646KB)(21)
Abstract:
The idea of biomigration was first proposed by Darwin (1859).He considered that any one species of organisms had only a single center of creation.So far as the environment allows it would migrate from the center to areas as far as possible. Adams' concept of center of dispersal (1902), Matthew's the...
