PROGRESS OF GEOMECHANICS IN OIL AND GAS EXPLORATION IN TARIM BASIN
Kang Yuzhu, Kang Zhijiang
1995, 1(2): 1-10.
Abstract (239) PDF (659KB)(28)
Abstract:
A systematic study of the formation and development of the Tarim Basin and the associated tectonic systems was made by applying the principle and methods of geomechanics in petroleum geology.In the process the author intended to determine the oil-gas province oil-gas-enriched zones and hydrocarbon p...
TECTONIC STRESS DRIVING AND MIGRATION OF GAS AND OIL IN NORTHERN TARIM BASIN
Shen Shumin, Feng Xiangyang, Liu Wenying
1995, 1(2): 11-20.
Abstract (234) PDF (706KB)(35)
Abstract:
The fault structures play an important role in controlling the formation, migration, accumulation and preservation of gas and oil in the northern Tarim Basin.The large repeatly active faults not only controlled the formation, development and evolution of large uplifts and depressions, but also acted...
RESEARCH ON FAULT CLOSURE OF OIL
Sun Baoshan, Zhou Xingui, Shao Zhaogang
1995, 1(2): 21-27.
Abstract (223) PDF (473KB)(28)
Abstract:
This paper discusses methods for fault closure studies and its relation to oil-gas migration and accumulation.Qualitative researches focus on the mechanical properties of faults, disposition of rock types on the two sides of a fault surface for the closure fault geometry, fault activity, and its rel...
EXPERIMENTAL STUDY OF THE PRINAPLE AND REGA-LARITY GOVERNING TECTONIC STRESS CONTROL OF ORE DEPOSITS
Wang Chengjin, Wand Yiqiang
1995, 1(2): 28-34.
Abstract (276) PDF (442KB)(41)
Abstract:
In this peper, the authors discuss the ore-bound principle of strain energy and ore solution migration under a specific tectonic stress field that prevaiced during mi neralization. It is thought that strain energy and migration potential are controlled by the sum and difference of the principal stre...
EXPERIMENTAL DETERMINATION OF RHEOLOGICAL BEHAVIOUR OF HTGHLY VISCOUS MODEL MATERIALS
Zeng Zuoxun, Liu Lilin, Huang Dinghua, Xia Qinglin, Huang Xuqiao
1995, 1(2): 35-39.
Abstract (219) PDF (302KB)(22)
Abstract:
This paper introduces the principle and method for determing the rheological behaviour of highly viscous materials.Not only can the apparent shear strain rates, and non-newtonian shear strain rates of the materials be determined thereby but also the flow indexes, stress indexes and apparent viscosit...
THE COLLATING AND STIPULATING OF “FENHE-WEIHE GRABEN” AND ITS SIGNIFICACE
Ning Chongzhi
1995, 1(2): 40-49.
Abstract (436) PDF (678KB)(36)
Abstract:
Data from different sources now available indicate that the "Fenhe-weihe graben" is actually composed of three separate enechelon arranged grabens, converging toward SW.The threee grabens had developed from the longitudinal tensiule faults on the crest of three antclines since Eocene and Pliocene ti...
GEOLOGICAL STRUCTURES AND THEIR CONTROL OF SILVER-GOLD ORES IN HUJIAJIAN AREA, JIANGXI
Dong Faxian
1995, 1(2): 50-58.
Abstract (290) PDF (833KB)(25)
Abstract:
The Hujiajian silver-gold area is located in the southern part of the Wuyuan-Wannian fault-fold zone with the NE-trending compressoshear faults as the leading structural elements.The NE-trending faults have experienced three stages of evolution:in the early stage, they behaved as sinistral compresso...
TECHNICAL OF METHODOLOGY IN THE ORE FIELD TECTONICS
Wang Jianping
1995, 1(2): 59-65.
Abstract (223) PDF (531KB)(41)
Abstract:
The author describes the technical structure of the methodology in the Ore field Tectonics researches in terms of the four technical systems in modern sciences, and classifies them as:observation and detection technique, experimental technique, modeling technique, and information processing techniqu...
PALAR WANDER AND TECTOGENETIC MOVEMENT
Li Pu
1995, 1(2): 66-70.
Abstract (279) PDF (386KB)(29)
Abstract:
The large displacements of the Earth rotation axis with respect to the entire mantle on a geologic time-scale, called true polar wander (TPW), is detected by paleomagneticians, and its order of magnitude is about 1°/Ma.TPW is supported by mantle rheology. Apparent polar mantler (APW) of a continent ...
APPLICATION OF PALEOMAGNETISM TO THE ANALYSIS OF BURIED STRUCTURES OF THE RONGDU GOLD DEPOSIT, ANHUI
Chen Bailin, Dong Faxian
1995, 1(2): 71-78.
Abstract (189) PDF (532KB)(18)
Abstract:
In this paper, the authors try to analyze the buried structures after determining the attitude of the sedimendary rocks and of the schistosity by measuring the remanent magnetization in core samples from the Rongdu gold deposit, Wuhe, Anhui.The results agree with the tectonic framework of the region...
CHARACTERISTICS OF TECTONIC MICRODOMAINS OF A WEAKLY CLEAVED QUARTZ SANDSTONE
Xu Xingwang, Ma Tianlin, Sun Liqian
1995, 1(2): 79-84.
Abstract (453) PDF (352KB)(30)
Abstract:
The difference between tectonic microdomains of a weakly cleaved quartz sandstone collected from the outer margin of a ductile shear zone shows that the development of cleavage in the rock depends on many factors, such asthe content and the size of sands, there will occur rotations and stretching of...
A PRELIMINARY STUDY OF CLINOPYROXENE-GARNET TRANSFORMATION IN ECLOGITE FROM MENGZHONG, JIANGSU PROVINCE
Chen Xuanhua, Wang Xiaofeng, Chen Zhengle, Shu Guiming, Li Xiaofeng
1995, 1(2): 85-89.
Abstract (225) PDF (345KB)(22)
Abstract:
The genesis of the Jiangsu-Shandong ultrahigh-pressure eclogites has so far remained a puzzling problem.The preliminary study of the prograde metamorphism of the eclogites as represented by the eclogite-garnetite transformation in this paper, provides some initial evidence for their origin as a mant...
MIDDLE PROTEROZOIC SEDIMENTARY SEPIOLITE DEPOSITS IN THE REGION OF BEIJING, TIANJING AND TANGSHAN
Zheng Daxing, Deng Jiwen, Qiu Yuanzheng, Zhang Ruifeng, Xu Gang, Wang Wenbin, Chen Baoli

Abstract (253) PDF (438KB)(21)
Abstract:
There is a wide distribution in the region of Beijing, Tianjing and Tangshan sedimentary sepiolite deposits which occur in the magnesium rich Carbonates of the Wumishan group of the middle Proterozic Jixian series.The geological structures of the region is simple with only weak magmatism.Investigati...
