2012, 18(1): 22-31.
Abstract (265) HTML (155) PDF (5177KB)(17)
Abstract:
In this paper, the present structural stress field of T40 reflection layer, the mechanic characteristics and structural active patterns of the second-level fault at the boundary of sub-depression and the third-and forth-level faults within sub-depression in Haian depression were analyzed. The direct...
CONTROLLING OF XIAKOU FAULT ON HYDROCARBON ACCUMULATION IN THE SOUTHERN PART OF HUIMIN DEPRESSION
WU Kong-you, ZHAO Zhong-xiang, Cui Shi-ling, LI Ji-yan
2012, 18(1): 32-41.
Abstract (199) HTML (109) PDF (4849KB)(12)
Abstract:
Xiakou fault plays an important role in controlling oil-gas accumulation in Huimin depression. By analyzing the lithologic association on two sides of fault, the mudstone-smearing and fault tightness index, Xiakou fault-sealing is studied quantitatively. The result shows that Xiakou fault sealing va...
DONGCHUAN MOVEMENT AND ITS INFLUENCE ON FOLDING STRUCTURES IN DONGCHUAN MINING DISTRICT
LIU Wei-ming, LIU Ji-shun, YIN Li-jun, YANG Li-gong, LIU Wen-heng, DOU Song
2012, 18(1): 42-51.
Abstract (215) HTML (105) PDF (2121KB)(12)
Abstract:
The various understandings about Dongchuan Movement were analyzed. Researches on characteristics of the strata in Kunyang Group, metamorphism, volcano-magma activities, and typical profiles as Tangdan, Luoxue and Tuobuka show that Dongchuan Movement is a large-scale tectonic movement. Dongchuan Move...
STUDY ON THE CONTROLLING STRUCTURE OF SALT DEPOSIT IN VIENTIANE PLAIN, LAOS
WANG Shao-hua, DU Jian-jun
2012, 18(1): 52-61.
Abstract (376) HTML (225) PDF (6119KB)(11)
Abstract:
The salt deposits in Vientiane Plain occurrence in Palaeocene Tagong Formation. The main Kalium-bearing minerals are carnallite and a little of sylvinite. During mineralization period, the Tagong Formation and salt deposits were controlled by NW-trending boundary faults and Tagong syncline. After mi...
QUANTITATIVE CALCULATIONS OF ENVIRONMENTAL DOSE RATE AT DIFFERENT INFLUENCING FACTORS IN LUMINESCENCE DATING
ZHANG Ke-qi
2012, 18(1): 62-71.
Abstract (280) HTML (174) PDF (1370KB)(19)
Abstract:
The environmental dose rate (D) in luminescence dating can be influenced by water content, cosmic ray, factor a, radon escape, etc. A series of detailed quantitative calculations were applied to the sample A1 with given U, Th and K content for D values using different parameter values of water conte...
