STUDY ON LATE CENOZOIC CRUSTAL TECTONISM
GAO Ming-xiu
2008, 14(4): 295-319.
Abstract (245) HTML (132) PDF (826KB)(24)
Abstract:
This paper deals with late Cenozoic crustal tectonism by studying morphostructure and associated water system in a global scope.As young mountain belt is caused by deep dissection at the edge of a plateau, the keynote of complex morphostructure on Earth surface is actually made up of sequentially fi...
METHODS TO CALCULATE THE FAULT-RELATED STRAIN
XU Shun-shan, Nieto-Samaniego AF, Alaniz-Álvarez SA
2008, 14(4): 320-327.
Abstract (262) HTML (351) PDF (284KB)(19)
Abstract:
This paper presents some methods for calculation of fault strain. The faulting can produce continuous and discontinuous strain. The continuous strain has positive relationship with the ratio of fault displacement vs fault length and with the effective stress on the fault plane. When calculating the ...
DISTRIBUTION, ORIGIN AND MINERALIZATION OF TWO TYPES OF CENOZOIC ADAKITE AND ADAKITE-LIKE ROCKS IN SOUTHEASTERN ASIA
ZHU Zhang-xian, YANG Zhen-qiang
2008, 14(4): 328-338.
Abstract (282) HTML (160) PDF (422KB)(11)
Abstract:
The Sunda Islands of southeastern Asia is an area where Cenozoic adakite and adakite-like rocks are well developed.These intermediate-acid magmatic rocks are widespread in Guinea Island, Sulawesi (Indonesia), Papua New Guinea, and scattered in Sumatra western Java, Banda island arc and Central Kalim...
TYPICAL TECTONIC STYLES AND THEIR GEOLOGIC SIGNIFICANCE IN EASTERN GUIZHOU PROVINCE
DAI Chuan-gu, ZHANG Hui, HUANG Qing-hua
2008, 14(4): 339-345.
Abstract (211) HTML (151) PDF (335KB)(19)
Abstract:
The Mesoproterozoic-Neoproterozoic to Cenozoic strata, including many types of magmatite and metamorphite, are developed in eastern Guizhou Province.Multi-periods of tectonic movements happening in the study region have been divided into Wuling structural cycle, Caledonian tectonic cycle, Yanshan te...
SUPERPOSITION AND RECONSTRUCTION OF MARINE MESO-PALEOZOIC STRATA BY MESO-CENOZOIC BASINS IN SOUTHERN CHINA
ZHOU Xiao-jin, YANG Fan
2008, 14(4): 346-361.
Abstract (216) HTML (128) PDF (1105KB)(13)
Abstract:
This paper focuses on the main basin prototypes developed in four tectonic evolution periods and their superposition in southern China during the Meso-Cenozoic.According to the superposition and tectonic reconstruction of basin prototype, five types of late reconstruction could be recognized for mar...
STRUCTURAL EVOLUTION AND HYDROCARBON ACCUMULATION IN THE XINDONG AREA OF DONGYING SAG, BOHAI BAY BASIN
HAN Qing-hua, YAN Peng, YU Zhao-hua, WU Shi-guo
2008, 14(4): 362-373345.
Abstract (304) HTML (238) PDF (691KB)(6)
Abstract:
The Xindong area is located at the conjunction of several structural belts, among which the Xinzhen structure constitutes the principal structural belt of the research area.The faults of the area display obvious growth and succession, and reached the acme in their development during the deposition o...
EXPERIMENTAL STUDY OF EFFECT OF TEMPERATURE ON COAL GAS PERMEABILITY UNDER GAS-SOLID COUPLING
YANG Xin-le, ZHANG Yong-li
2008, 14(4): 374-380.
Abstract (343) HTML (114) PDF (264KB)(7)
Abstract:
To observe the effect of temperature on coal gas permeability, an experiment of coal gas permeability was carried out at different temperatures through a three-axial penetration instrument.The results show that, at different temperatures, the permeability of coals assumes a trend of quadric parabola...
SENSITIVITY ANALYSIS ON FACTORS INFLUENCING LANDSLIDE STABILITY AND DISCUSSION ON ITS TREATMENT DESIGN
MA Xian-chun, WANG Lei, ZHAO Fa-suo
2008, 14(4): 381-388.
Abstract (217) HTML (125) PDF (239KB)(9)
Abstract:
The factors influencing landslide stability coefficients include cohesion of soil in the slide zone, internal friction angle, unit weight of the slide and the pore water pressure, etc.They affect the lan dslide stability coefficients in different degrees, so that one imposing the greatest influence ...
