Abstract (226) PDF (284KB)(12)
Abstract:
According to the recent survey evaluation and integrated study of mineral resources in South China, this paper summaries the characteristics of structural control of ore deposition at different spatial lev els, from the lithosphere to microfracture networks, including deep lithosphere delamination a...
TYPES AND STRUCTURAL CONTROL OF GOLD DEPOSITS IN THE TONGGUANSHAN ORE FIELD,ANHUI PROVINCE
WAN Ren-hu
2004, 10(2): 122-128.
Abstract (190) PDF (233KB)(12)
Abstract:
Tongguanshan is a famous copper ore field and one of copper-producing areas of China. Recently a number of gold deposits have been found, which belong to the sulfide type and gossan type and are genetically related to copper deposits in the ore field. The paper mainly deals with the types, geologica...
CHARACTERISTICS OF GEOLOGICAL STRUCTURE OF THE XINCHENG GOLD DEPOSIT,JIAODONG,AND DIRECTION IN GOLD PROSPECTING AT DEPTH
ZHAO Hai, ZHAO Ke-guang, MA Yao-li, XIU Chun-hua
2004, 10(2): 129-136.
Abstract (243) PDF (241KB)(14)
Abstract:
The Xincheng gold deposit has been mined for more than 20 years and the service life of its remaining ore tonnage decreases gradually, thus affecting the sustainable development of the mine.The discovery of blind orebody No. V demonstrates that the deep part of the deposit has favorable geological c...
CHARACTERISTICS OF MAJOR FAULT ZONES IN THE QIANJIA AREA AND ANALYSIS OF ROCK AND ORE CONTROL
LI Sun-xiong, MO Wei-ming, YUN Ping, FAN Yuan
2004, 10(2): 137-145.
Abstract (308) PDF (308KB)(8)
Abstract:
The fault zones in the Qianjia area are mainly of NW, NE and N-S trends and geomechanically of tenso-shear and compresso-shear origin.They originated in the Yanshanian period. The N-S-trending fault zone has been most strongly deformed and altered and is characterized by strong enrichment in Mo, Ag,...
MANIFESTATIONS OF THE COMPLEXITY OF SEDIMENTARY BASINS OF CHINA AND ANALYSIS OF THEIR ORIGIN
TONG Heng-mao, CAO Dai-yong, QIN Hong
2004, 10(2): 146-154.
Abstract (262) PDF (289KB)(22)
Abstract:
The complexity of sedimentary basins of China is mainly manifested in the following nine aspects:(1) large number, small size and wide distribution;(2) a great variety of basin types;(3) prevalence of the phenomenon of multi-stage basin superimposition and compounding;(4) dominance of continental se...
GEODYNAMICS PROCESS IN THE JUNGGAR BASIN
CHEN Ye-quan, WANG Wei-feng
2004, 10(2): 155-164.
Abstract (316) PDF (307KB)(17)
Abstract:
The Junggar basin is surrounded by Paleozoic sutures and the mountains around the basin have been thrust toward the basin, showing that this basin has been in a long-continued, compressional regime.The change of volcanic rocks from marine facies to continental facies and change of volcanism from str...
CENOZOIC SEQUENCE STRATIGRAPHY AND CHARACTERISTICS OF THE SEDIMENTARY SYSTEM IN THE SHUBEI AREA,LIAOHE BASIN
LI Wen-quan, LIU Li, JIAO Li-juan, WANG Li
2004, 10(2): 165-171.
Abstract (206) PDF (251KB)(11)
Abstract:
The Shubei area is a secondary unit of the West subbasin of the Liaohe basin and a Cenozoic rift basin that developed on the Archean and Meso-and Neoproterozoic basements.The Cenozoic strata may be divided in ascending order into the Paleogene Fangshenpao Formation, Shahejie Formation and Dongying F...
APPLICATION OF ACOUSTIC EMISSION IN THE STUDY OF THE NUMBER OF CENOZOIC TECTONIC PHASES IN THE DONGYING SUBBASIN
XU Jian-chun, DAI Jun-sheng
2004, 10(2): 172-178.
Abstract (244) PDF (206KB)(9)
Abstract:
Acoustic emission as a method of measuring ground stresses has aroused increasing interset. Rock has the function of "memory" of its stress history.By using this function, the authors applied acoustic emission to the analysis of rock samples from the Dongying subbasin and obtained the ground stress ...
TECTONIC STRESS FIELD IN THE DA'ANZHAI MEMBER OF THE LANGZHONG AREA,NORTHERN SICHUAN,AND FORECAST OF PETROLEUM ACCUMULATIONS
CAO Cheng-jie, ZHOU Xin-gui, SHU Neng-yi, YAN Bin, LUO Guo-shi, XING Zhen-hui
2004, 10(2): 179-187.
Abstract (226) PDF (384KB)(14)
Abstract:
On the basis of a tectonic analysis, the authors have studied the basic characteristics of the tectonic field since the Mesozoic in the Da'anzhai Member of the Langzhong area, northern Sichuan.An attempt has been made to forecast petroleum accumulations in the Da'anzhai Member using the theory and m...
APPLICATION OF LOGGING-CONSTRAINED INVERSION IN THE PREDICTION OF SUBTLE PETROLEUM ACCUMULATIONS-A CASE STUDY OF THE K46 WELL AREA OF THE DAGANG OILFIELD
HOU Bo-gang, FAN Jun-xia, HUANG Guo-ping, WU Bo-fu, LU Feng-ting
2004, 10(2): 188-192.
Abstract (209) PDF (199KB)(8)
Abstract:
The prediction of reservoirs is a key point as well a difficult point in exploration for subtle petroleum accumulations.Logging-constrained inversion is an effective method for predicting subtle reservoirs.A rational initial acoustic impedance model was constructed by correcting the log data, extrac...
