1995, 1(1): 1-7.
Abstract (282) PDF (517KB)(31)
Abstract:
After an overview of what have so far been suggested for earth movements, e. g. tectonic systems and global movement field, plate tectonics and rotational spreading,faultblock structure,mosaic structure,geodepression theory and rotation of the earth,as well as a discussion on the directionality of t...
THE RESPONSE OF THE CRUST AS TECTONIC MOVEMENTS TO THE CHANGES OF ECCENTRICITY OF THE EARTH'S ORBIT
Wu Xihao, Jiang Fuchu, Xiao Huaguo
1995, 1(1): 8-14.
Abstract (278) PDF (519KB)(30)
Abstract:
The main tectonic events and climatic changes which occurred in the last 3Ma coincide with the Earth's orbital eccentricity changes having a period of about 0.4Ma. The boundaries of tectonoclimatic cycles determined from the stratigraphic records in the Loess Plateau giving solar calendar ages of 0....
DIRECTIONAL AND EQUIDISTANT DISTRIBUTION OF MID-OCEANIC RIDGES AND THE MECHANISM OF THEIR FORMATION
Wu Zhenghan, Cui Shengqin
1995, 1(1): 15-24.
Abstract (221) PDF (687KB)(28)
Abstract:
The present directional and equidistant distribution of the mid-oceanic ridges on foe earth's surface,the sinusoidal oppositely compensating top and bottom surfaces of the asthenosphere across the ridges,the long development of synchronous tholeiitic rocks symmetrically arranged on either side of th...
GEOMAGNETIC REVERSAL FREQUENCY SINCE THE CARBONIFEROUS AND THE GEODYNAMICS
Yang Zhenyu
1995, 1(1): 25-30.
Abstract (267) PDF (415KB)(27)
Abstract:
On the basis of the magnetic time scale and magnetostratigraphic results,the relationship between changes of the magnetic reversal frequency and core/mantle coupling,especially the episodic evolutions of the D" layer since the Carboniferous, was analysed. The episodic geomagnetic reversal friquencie...
RECENT PROGRESS OF THE STUDY ON REGIONAL CRUSTAL STABILITY IN CHINA
Wu Shuren, Chen Qingxuan, Sun Ye
1995, 1(1): 31-37.
Abstract (332) PDF (482KB)(38)
Abstract:
The study of regional crustal stability is considered as a branch between engineering geology and the closely allied geomechanics as well as structural geology. Since the last decade,great progress has been achieved with the rapid development of urban construction and large engineering works,resulti...
RESEARCH OF THE SEISMIC FAULT ON THE NORTHEASTERN MARGIN OF THE QINGHAI-TIBETAN PLATE
Dai Huaguang, Jia Yunhong, Liu Hongchun, Su Xiangzhou, Chen Yongming
1995, 1(1): 38-43.
Abstract (218) PDF (439KB)(30)
Abstract:
The northeastern marginal area of the Qinghai-Tibetan plateau is one of the most tectonically and seismically active regions in China since Quaternary, especially late Pleistocene. It is also one of the regions which are of the highest great earthquake (Ms ≥ 7) frequency. A detailed research on the ...
THE LATITUDINAL NAPPE STRUCTURE IN THE SUNITEZUOQI OF INNER MONGOLIA
Li Shujin, Zhang Weijie
1995, 1(1): 44-52.
Abstract (206) PDF (798KB)(23)
Abstract:
Along the line connecting Tuhamohalagan and Jiaoqier, in the central left Sunite Banner of the Inner Mongolia Autonomous Region, the authors have found a latitudinal nappe zone extending for some 60km. Within the belt,the mid-late Proterozoic(epimetamorphic) green-schists were ovethrust from south t...
ON THE FORMATION OF YARLUNG ZANGBO RIVER FAULT ZONE
Lao Xiong
1995, 1(1): 53-59.
Abstract (378) PDF (510KB)(45)
Abstract:
The Yarlung Zangbo River fault zone cosists of four arcuate faults bending towards the southwest. The fault zones had become successively subsided from the northwest to the southeast to receive sediments from late Triassic up to the Quaternary,with the adjoining regions uplifted. The crustal movemen...
A PRELIMINARY NOTE ON DYNAMOMETAMORPHISM DUE TO TECTONIC FORCES
Wang Zhishun, Zhu Dagang
1995, 1(1): 60-66.
Abstract (300) PDF (538KB)(41)
Abstract:
In this article a basic concept on dynamometamorphism as a result of the action of tectonic forces is presented. This means the metamorphism caused by the deformation and factes transformations of rocks and minerals during the tectonic movement in response to the tectonic forces and the resulting ri...
ANALYSIS OF THE FORMATION OF THE “NORTH CHINA SYSTEM”, A CENOZOIC TECTONIC SYSTEM
Yi Mingchu
1995, 1(1): 67-75.
Abstract (238) PDF (593KB)(22)
Abstract:
The "North China system" is a tectonic system that trends NNW and was widely developed in the North China Block in Cenozoic with the Changping-Weichang area as a type locality. It is also called "Luanhe tectonic system" because about 40 percent of their occurrences are concentrated in the Yixunhe-Lu...
SIGNIFICANCE OF THE STUDY OF REPEATED MOVEMENT OF FAULTS
Liu Zhigang, Cui Hongqing, Sun Dianqing
1995, 1(1): 76-81.
Abstract (299) PDF (769KB)(28)
Abstract:
During the long geologic times, an area may have experienced repeated crustal movements in different directions and in different manners thus resulting in different stress fields. Most of the pre-existing faults would be reactivated under changing stress fields to be imparted some new mechanical pro...
MODELLING OF MINERALIZATION STRESS FIELD AND CONCEALED DEPOSITS PREDICTION IN LIANHUASHAN GOLD-ORE FIELD OF INNER MONGOLIA
Jiang Xirong, Zhao Yinzhen, Xiao jinmin
1995, 1(1): 82-87.
Abstract (226) PDF (452KB)(32)
Abstract:
Mineralization is the process of the movement of ore forming materials. The activation,migration and concentration of ore-forming elements closely correlates with the accumulation of stress and energy when "the syn-metallogenic structural system" became active and with the release of stress and ener...
THE RELATION BETWEEN ALBITIZATION AND GOLD IN THE DUCTILE SHEAR ZONE OF DAGOUGU AREA, NORTHERN GUANGDONG PROVINCE
Zhu Dagang
1995, 1(1): 88-94.
Abstract (320) PDF (541KB)(25)
Abstract:
This is a preliminary summation of the geological features of the cataclastic albitite type gold deposit in Dagougu area,northern Guangdong Province. With a general description of the macroscopic and microscopic features of the ductile-brittle shear zone and its evolution,and also a discussion on th...
