Abstract (282) HTML (95) PDF (730KB)(24)
Abstract:
On the basis of research at home and abroad, starting from the landslide mechanism establish geomechanical model of landslides with low dip angle strata, all the parameters in the model, such as landslide size, slip angle, back edge ripping slot seeper depth and so on, were obtained by digital lands...
NUMERICAL SIMULATION OF STRUCTURAL FRACTURES CONTROLLED BY PIQIANG STRIKE-SLIP FAULT
ZHANG Qing-lian, HOU Gui-ting, PAN Wen-qing, HAN Jian-fa, LI Le, JU Wei
2012, 18(2): 110-119.
Abstract (508) HTML (175) PDF (573KB)(15)
Abstract:
Based on the intensive research on development of structural fractures that controlled by the Piqiang strike-slip fault, this paper has simulated the distribution of structural fractures under the influence of the regional deviatoric stress, the width and trend of the strike-slip fault through the "...
CONTROLLING OF STRUCTURAL STRESS FIELD TO THE FRACTURES IN XUANHAN-DAXIAN REGION, NORTHEASTERN SICHUAN BASIN, CHINA
TANG Yong, MEI Lian-fu, CHEN You-zhi, TANG Wen-jun, XIAO An-cheng
2012, 18(2): 120-139.
Abstract (246) HTML (98) PDF (1545KB)(16)
Abstract:
Structural stress field is one of the main reasons on fracture formation. It is the key of prediction structural fracture that paleostructure stress field is microscopically quantitative calculated.So we can well understand the fracture distribution in underground strata based on careful analysis to...
RELATIONSHIP BETWEEN CENOZOIC TIANSHAN MOUNTAIN UPLIFTING AND CURRENT TECTONIC TOPOGRAPHY IN NORTH MARGIN OF TARIM BASIN:AN EVIDENCE FORM ROCK ACOUSTIC EMISSION
ZHANG Yu-hang
2012, 18(2): 140-148, 194.
Abstract (331) HTML (150) PDF (568KB)(12)
Abstract:
Strongly tectonic activity had been observed by field outcrop in the northern margin of the Tarim Basin. In order to find out regional stress field setting of active structure movement, the authors collected rock acoustic emission samples in Sishichang and Kuqa River section in the north margin of t...
THE INVESTIGATION OF NORMAL FAULT UNDER UPWELLING FORCE AND ITS CRITICAL STRESS STATE
SONG Sui-hong, CHEN Shu-ping, HE Ming-yu
2012, 18(2): 149-157.
Abstract (308) HTML (179) PDF (308KB)(11)
Abstract:
The investigation of normal fault formed under tectonic setting of upwelling force and its critical stress state is of significance in the structural interpretation and the hydrocarbon migration. Based on the theory of parabolic Mohr failure envelope, and certain assumptions, mathematical derivation...
NUMERICAL SIMULATION OF HOLE CREEP SHRINKAGE FOR COMPOSITE ROCK SALT LAYERS
ZENG De-zhi, LIN Yuan-hua, LU Ya-feng, ZHU Da-jiang, LI Liu-wei
2012, 18(2): 158-164.
Abstract (183) HTML (137) PDF (341KB)(10)
Abstract:
Salt rocks have very strong creep behaviors in HTHP environment in deep formations, complex accidents such as hole shrinkage, drill pipe sticking, etc. occurring frequently. Current methods to calculate the safe drilling mud density are mainly used in circumstances of homogeneous earth stress. The 3...
POTENTIAL GENESIS OF THE TRENDING CHANGES OF JINNING PERIOD AND CALEDONIAN STRUCTURAL LINEAMENS IN MIDDLE-SOUTHERN HUNAN
BAI Dao-yuan, JIA Bao-hua, ZHONG Xiang, JIA Peng-yuan, LIU Yao-rong
2012, 18(2): 165-177.
Abstract (254) HTML (139) PDF (1007KB)(7)
Abstract:
There existed visible lateral variations of the Jinning Period and Caledonian structural lineaments in middle-southern Hunan. The Jinning Period and Caledonian structural lineaments in Tongdao-Xupu-Anhua-Taojiang area showed an arc bulging to northwest. The Jinning Period lineaments trend in Liuyang...
MOLYBDENITE Re-Os ISOTOPIC DATING OF SANGBUJIALA COPPER DEPOSIT IN THE SOUTH MARGIN OF THE EASTERN GANGDESE SECTION, TIBET, AND ITS GEOLOGICAL IMPLICATIONS
ZHAO Zhen, HU Dao-gong, WU Zhen-han, LU Lu
2012, 18(2): 178-186.
Abstract (246) HTML (146) PDF (701KB)(6)
Abstract:
Located in north side of Yaluzangbujiang Suture, Sangbujiala skarn-type copper deposit is one of the typical polymetallic deposits in the south subzone of the Gangdese metallogenic belt. For the purpose of finding out the mineralization time, the authors selected eight molybdenite samples from Sangb...
STRUCTURAL CHARACTERISTICS OF TONGCHENG FAULT AND HYDROCARBON ACCUMULATION IN JINHU SAG
YE Shao-dong
2012, 18(2): 187-194.
Abstract (292) HTML (122) PDF (479KB)(6)
Abstract:
Tongcheng Fault is a second class fault which controlls the development of Tongcheng structural belt in Jinhu Sag.It is divided into two parts by its faulted feature showing reverse fault character at the south part and normal fault feature at the north part.There are different views about its chara...
EVALUATION OF WATER SOLUBLE HELIUM RESOURCES IN WEIHE BASIN
ZHANG Fu-li, SUN Qi-bang, WANG Xing-yun, ZOU Yan-rong
2012, 18(2): 195-202.
Abstract (225) HTML (123) PDF (268KB)(9)
Abstract:
The discovery of water soluble helium in Weihe Basin was introduced in this paper.Researches showed that the water soluble helium resources in Weihe Basin the resources are widely distributed and highly graded in Weihe Basin. The cause types of water-soluble gas are of different rock multi-source mi...
