ASTHENOSPHERIC STATIC PUSH AND ITS IMPLICATIONS TO PLATE DYNAMICS
WEI Dong-ping
2000, 6(1): 4-14.
Abstract (275) PDF (566KB)(8)
Abstract:
Lithospheric plates are exerted by a fluid pressure,since they immediately overlie the asthenosphere. We define this fluid pressure as Asthenospheric Static Push (ASP). For a oceanic plate,there is no difference of ASP and the traditional ridge push force. Assuming a decoupling of horizontal compone...
A DYNAMICAL MODEL FOR CONTINENTAL DRIFT AND EXPERIMENTAL SIMULATED RESULTS
QIAN Wei-hong
2000, 6(1): 15-21.
Abstract (327) PDF (251KB)(14)
Abstract:
In this paper, a simple dynamical model for simulating continental drift is formulated based on the angular momentum exchange between inner solid core and outer liquid core during the early stage of the Earth formation. The drift of ideal continental plate as well as the formation of mountains and i...
PHYSICAL EXPERIMENTS ON MANTLE UPLIFTING AND CONTINENT EXTENSION
ZHOU Yong-sheng, LI Jian-guo, WANG Sheng-zu
2000, 6(1): 22-32.
Abstract (212) PDF (495KB)(7)
Abstract:
In the present paper,an experiment of the mantle uplifting and lateral extension is conducted under three different boundary conditions using a ductile/brittle double-layer physical model. The experiment results show that when the model is fixed on two sides,uplifting could cause stretch and faults ...
ON THE METHOD OF TECTONIC SIEVING
QIU Yuan-xi
2000, 6(1): 33-43.
Abstract (137) PDF (409KB)(12)
Abstract:
The method of tectonic sieving was developed by J.S. Lee(LI Si-guang) in 1942.It is to sort out tectonic structures of different phases from a complex of tectonic features of all phases,including formational and deformational ones.
The first and foremost step is to decide the time sequence of each ph...
THREE DIFFERENT TYPES OF PHANEROZOIC OROGENESIS OF NORTHERN BORDER AREA OF NORTH CHINA CRATON
WU Zhen-han
2000, 6(1): 44-51.
Abstract (247) PDF (367KB)(10)
Abstract:
Three different types of Phanerozoic orogenesis are identified in the northern border area of North China Craton.In the Paleozoic era,the northern border area of North China Craton belonged to the tectonic domain of south peri-Paleozoic ocean and is characterized by subduction-collision orogenesis,l...
THE CHARACTERISTIC FEATURES OF LATE HERCYNIAN-INDOSINIAN TECTONIC ACTIVITIES OF THE LEFT SONID BANNER AREA,INNER MONGOL AUTONOMOUS REGION
GAO De-zhen
2000, 6(1): 52-58.
Abstract (170) PDF (247KB)(8)
Abstract:
The region of Left Sonid Banner of Inner Mongolia is located in the Xing-Meng fold zone of the northern rim of the North China Plate.A comparative study of the shapes of the ENE-trending folds,the causative axial loading and the resulting shortening as well as the geometry of the faults and ductile ...
AN ANALYSIS OF THE ACTIVITY OF THE SHENZHEN FAULT ZONE IN THE TUNNEL ENGINEERING IN SHENZHEN MUNICIPALITY
SUN Ye, ZHAO Xian, XU Xiang-ying, LIU Ting, TAN Cheng-xuan, YANG Geng, YAN Quan-ren, YE Wei-guo, YANG Shi-ping, HE Guang-hai, LI Shu-fen, SUN Dong-xun
2000, 6(1): 59-68.
Abstract (239) PDF (349KB)(10)
Abstract:
After an analysis of the evolution of the activity of the Shenzhen fault zone numerical simulations of both plane-and 3-D present tectonic stress fields are made to calculate quantitatively the angle enclosed between the maximum horizontal principal compressive stress direction and the tunnel axis a...
ON THE FORMATION OF THE BANGONG-CO-NUJIANG FAULT ZONE
LAO Xiong
2000, 6(1): 69-76.
Abstract (470) PDF (276KB)(13)
Abstract:
The Bangong-Co-Nujiang fault zone consists of four arcuate faults.The zone was subsided successively from north to south to receive sediments derived from the two immediately adjoining uplifted flanks in the late Triassic to the Cretaceous.It was the results of undulated earth's movement.
FINITE STRAIN STUDY ON PALEOZOIC STRUCTURES IN CHENGDAO REGION
DAI Jun-sheng, MENG Zhao-ping
2000, 6(1): 77-83.
Abstract (157) PDF (248KB)(5)
Abstract:
This paper applies the theory of finite strain to the study of Paleozoic structures in Chengdao region.A displacement function is established by resolving the straining processes based on the analysis of the basic tectonic features and their evolution.The E-W,N-S and vertical components of the displ...
STUDIES ON THE FEATURES OF THE HOLBAOJINAO QUARTERNARY SALT LAKE IN MID-NORTH ERDOS BASIN
TIAN Xiao-xian
2000, 6(1): 84-89,94.
Abstract (190) PDF (232KB)(5)
Abstract:
The present paper discusses the characteristics of the Holcene Holbojinao salt lake deposits in Mid-north Erodos Basin with a full description of the chemical composition,salinity,type of water chemistry and pH value of the surface brine.A study of the sedimentary regime salinity variation,and the c...
GRANITE HOODOOS(ARSIHATY)——A NEW GEOMORPHIC LANDSCAPE
QIAN Fang, HE Pei-yuan, HAO Zhi
2000, 6(1): 90-94,99.
Abstract (337) PDF (389KB)(12)
Abstract:
A landscape of granite hoodoos can be seen well developed in Beidashan of the Daixingainling mountain range in Keshiketeng county,Inner Mongol Autonomous Region.Granite hoodoos are formed by freezing,weathering,aeolation of the jointss and crackes developed in the granite.There can be distinguished ...
