2007, 13(4): 307-314.
Abstract (203) HTML (87) PDF (772KB)(11)
Abstract:
On the basis of the field investigation, digital elevation modeling and remote sense data analysis, the authors think that the nearly E-W-trending watersheds and valleys in the Lhasa area are distributed alternately from north to south under the nearly N-S compression, parallelly to the WNWtrending ...
GRAIN-SIZE DISTRIBUTION AND GENESIS OF LOESS IN THE QINGZHOU AREA, SHANDONG
PENG Shu-zhen, GAO Zhi-dong, WU Xiu-ping, ZHANG Lian-bing, LIANG Ming-ying, QIAO Yan-song
2007, 13(4): 315-321.
Abstract (278) HTML (293) PDF (299KB)(15)
Abstract:
Loess deposits with varying thicknesses are widely distributed on intermontane valleys and piedmont zones on the northern side of the central Shandong mountainous region.A systematic grain-size analysis was performed along the Fujiazhuang loess section of the Qingzhou area.The analytic results of th...
ORIGIN OF QUATERNARY MUDDY GRAVEL DEPOSITS IN THE LUSHAN AREA
LIU Zong-xiu, ZHAO Zhi-zhong, TIAN Jiao-rong, WANG Min, LI Ming-ze
2007, 13(4): 322-332, 314.
Abstract (298) HTML (174) PDF (527KB)(7)
Abstract:
The gravel fabric characteristics of Quaternary muddy gravel deposits in the Lushan area indicate the following:the lithology of gravels is almost consistent with that of bedrocks in the mountains; the isometric sphere diameter of gravels is small, the weighted average diameter of gravels is lower t...
CHARACTERISTICS OF POLLEN ASSEMBLAGES IN SURFACE SOILS IN THE MAQU-HONGYUAN AREA, ZOIGÊ PLATEAU, NORTHERN SICHUAN

2007, 13(4): 348-354.
Abstract (223) HTML (117) PDF (419KB)(6)
Abstract:
The physical properties, seismic reflection features, geometry and halite-related hydrocarbon accumulation types in the Wenliu oilfield of the Dongpu subbasin were studied by using seismic reflection data, combined with geological and drilling data.The studies show that halite is characterized by a ...
DOMINANT CONTROLLING FACTORS AND REGULARITIES OF FORMATION OF PETROLEUM ACCUMULATIONS IN THE TAZHONG AREA
LIU Chun-xiao, QIAN Li, DENG Guo-zhen

Abstract (320) HTML (106) PDF (757KB)(11)
Abstract:
Because of many influence factors, the formation of petroleum accumulations is complex in the Tazhong area.Analysis of drilled petroleum accumulations shows that the main controlling factors affecting the formation of petroleum accumulations in the area include:① source rock; ② migration channels (f...
UPSCALE METHOD FOR THE FINE 3D GEOLOGICAL MODEL OF HYDROCARBON RESERVOIRS AND ITS APPLICATION EFFECTIVENESS
SUN Zhi-xue, LU Hong-jiang, SUN Zhi-lei
2007, 13(4): 368-375.
