SAND GRAINS CANNOT "FLY FAR AND HIGH"———A BASIC PRINCIPLE ABOUT "DUST STORMS"
ZHANG Hong-ren
2007, 13(1): 1-6.
Abstract (316) HTML (237) PDF (186KB)(7)
Abstract:
Sand and dust are both products of physical weathering.However, their behaviors are entirely different in the eolian transport process.A rigorous physical test performed by Bagnold proved that dust can fly up to 3000 m high over great distances with wind, while sand grains can move at most by means ...
AN APPROACH TO THE STUDY OF COAL AND GAS OUTBURSTS
SUN Ye, TAN Cheng-xuan, SUN Wei-feng, WANG Rui-jiang, WU Shu-ren, CHEN Qun-ce
2007, 13(1): 7-14.
Abstract (4028) HTML (150) PDF (278KB)(25)
Abstract:
The overlapping of tectonic stress, rock mass energy concentration and mining-induced stress is the basic cause for coal andgas outbursts.Coal and gasoutbursts, which are one of the manifestations of present tectonic activities and induced by crustal instability, belong to the research content of ge...
RISK ANALYSIS AND PREDICTION OF EARTHQUAKES IN THE CONSTRUCTION AREA OF THE WEST LINE OF THE SOUTH-TO-NORTH WATER DIVERSION PROJECT
PENG Hua, MA Xiu-min
2007, 13(1): 15-24.
Abstract (326) HTML (120) PDF (516KB)(10)
Abstract:
The paper discusses the distinguishing features of earthquake activities in the construction area of the west line of the project of water diversion from the upper Yangtze River in the south to the upper Yellow River in the north.According to these features, by using the regional earthquake data and...
LATITUDINAL CONVERGENCE OF THE ASIAN CONTINENT, RISE OF THE QINGHAI-TIBET PLATEAU AND EXPANSION OF THE EAST ASIAN CONTINENT
LI Shu-jing
2007, 13(1): 25-30, 50.
Abstract (204) HTML (65) PDF (299KB)(17)
Abstract:
The tectonic problem of East Asia is one of the focuses of the world's concern. In East Asia stand two magnificent plateaus —the Mongolia Plateau and Qinghai-Tibet Plateau —and between the two plateaus lie E-W-trending modern mountain systems such as the Tianshan-Yinshan and Kunlun-Qinling mountain ...
3D MODEL OF REVERSED S-SHAPED OROGENIC BELTS ON THE CONTINENTAL MARGIN : WITH A DISCUSSION OF THE INTERNAL STRUCTURE AND UPLIFT OF THE QINGHAI-TIBET PLATEAU
LI Dong-xu
2007, 13(1): 31-41.
Abstract (282) HTML (104) PDF (417KB)(9)
Abstract:
According to the tectono-geomorphological features and characteristics of neotectonic movement on the southwestern margin of the North American continent, the author has established a 3D tectonomechanic model of the reversed S-shaped continental-margin orogenic belt of the northern hemisphere. This ...
CRETACEOUS DENUDATION OF THE ILI BASIN AS REVEALED BY FISSION-TRACK THERMOCHRONOLOGY
GONG Hong-liang, CHEN Zheng-le, HU Yuan-qing, LI Li, Li Sheng-xiang, ZHENG En-jiu, HAN Xiao-zhong
2007, 13(1): 42-50.
Abstract (228) HTML (92) PDF (397KB)(7)
Abstract:
The fission-track dating method has been widely used to constrain the exhumation of mountains and tectono-thermal evolution of basins.This paper mainly presents the results of apatite fission-track dating and discusses the Mesozoic uplift-denudation event in the Ili basin.Fission-track dating reveal...
SEQUENCE STRATIGRAPHY AND PETROLEUM ACCUMULATION IN FORELAND BASINS
LIU Gang, DONG Shu-wen
2007, 13(1): 51-59.
Abstract (240) HTML (162) PDF (321KB)(11)
Abstract:
From a tectonic point of view, foreland basins related to plate collision are areas favorable for petroleum accumulation.Collision of two plates form a series of orogenic belts, while foreland basins tend to form in the fronts of relatively stable plates.The characteristics of foreland basins make t...
SEQUENCE STRATIGRAPHY OF THE BAYAN QAGAN SUBBASIN IN THE EREN BASIN AND APPLICATIONS FOR PETROLEUM EXPLORATION
LI Jin-liang, FAN Tai-liang, ZHANG Yue-qiao
2007, 13(1): 60-69.
Abstract (240) HTML (141) PDF (563KB)(8)
Abstract:
Based on an analysis of well-log data and seismic profiles, the authors have identified the main sequence boundaries in the Bayan Qagan subbasin of the Eren basin, established the sequence stratigraphic framework of the subbasin and described the types of sedimentary facies and their plan distributi...
ANALYSIS OF HIGH-RESOLUTION SEQUENCE STRATIGRAPHY AND STUDY OF DEPOSITIONAL SYSTEMS IN THE MALING OIL FIELD, ORDOS BASIN
WANG Chun-yu, ZHANG Zhi-guo, LI Zhao-ming, ZHANG Lin-yan, ZHANG Hong-bin, YANG Zhi-guo
2007, 13(1): 70-77, 96.
Abstract (285) HTML (144) PDF (440KB)(6)
Abstract:
Based on the theory of base-level cycles, two long-term, six medium-term and twenty-seven short-term cyclic sequences can be distinguished in the Jurassic Yan'an Formation and Fuxian Formation in the Maling oil field, Ordos basin.This paper introduces in more detail the controls of the base level on...
LATE QUATERARY NEOTECTONIC MOVEMENT OF THE JIAYUGUAN FAULT
CHEN Bai-lin, LIU Jian-sheng, ZHANG Yong-shuang, LIU Jian-min
2007, 13(1): 78-85.
Abstract (195) HTML (245) PDF (401KB)(30)
Abstract:
The Jiayuguan active fault is situated near Jiayuguan City.It is closely related to the Jiayuguan-Wenshushan uplift (which is one of the three uplifts in the Hexi Corridor:the JiayuguanWenshushan uplift in the western part of the Hexi Corridor, Yumushan uplift in the central part of the Hexi Corrido...
CHARACTERISTICS OF CENOZOIC FAULT ACTIVITIES IN THE HUIMIN SUBBASIN
WANG Shu-bao, ZHONG Jian-hua, CHEN Zhi-peng
2007, 13(1): 86-96.
Abstract (204) HTML (99) PDF (519KB)(10)
Abstract:
The parameters of Quaternary fault activities such as the growth index, fault throw and fault activity rate are calculated to analyze the characteristics of fault activities in the Huimin subbasin and four orders of subbasin-controlling faults are distinguished.The analysis indicates the following:t...
