2007, 13(2): 99-109.
Abstract (296) HTML (141) PDF (391KB)(25)
Abstract:
The Baidunzi-Xiaoxigong ductile shear zone, as the southernmost one of the eight ductile shear zones in the Beishan area, Gansu, is situated at the southern border of the southern Beishan area and near the northern border of the Dunhuang massif.It extents in a nearly E-W direction with a length of 1...
ORE-CONTROLLING EFFECT OF NAPPE STRUCTURE IN THE EAST ORE ZONE OF THE BAIYANGPING AREA, LANPING BASIN, YUNNAN
HE Long-qing, JI Wei, CHEN Kai-xu, YU Feng-ming, WEI Jun-qi, YANG Ai-ping, YANG Wei-guang
2007, 13(2): 110-118.
Abstract (248) HTML (113) PDF (324KB)(10)
Abstract:
The nappe structure in the east ore zone of the Baiyangping area, Yunnan, is a front of the thrust nappe system of a foreland basin related to the Jinshajiang-Ailaoshan orogenic belt, belonging to the emergent imbricate fan-type front.In the mining area the Huachangshan fault and Shuimofang fault fo...
SYSTEM ANALYSIS OF ORE-CONTROLLING STRUCTURE IN THE NORTHWESTERN JIAODONG GOLD METALLOGENIC BELT
GUO Tao, LÜ Gu-xian
2007, 13(2): 119-130.
Abstract (238) HTML (161) PDF (690KB)(16)
Abstract:
Take for example the northwestern Jiaodong metallogenic belt, this paper attempts to use the system analysis to study the characteristics of regional mineralization and regional ore controls.The authors think that deep structure controlled the spatial distribution of the northwestern Jiaodong metall...
SULFUR ISOTOPE FEATURES OF CU-AU POLYMETALLIC DEPOSITS IN THE HONGLIUGOU-LAPEIQUAN AREA ON THE NORTHERN MARGIN OF THE ALTYN TAGH MOUNTAINS AND THEIR RELATION TO THE TECTONIC EVOLUTION
LI Yue-chen, CHEN Bai-lin, CHEN Zheng-le
2007, 13(2): 131-140.
Abstract (303) HTML (247) PDF (376KB)(9)
Abstract:
The northern margin of the Altyn Tagh Mountains is one of the important metallogenic provinces recently found in northwestern China.Based on the sulfur isotope study of Cu-Au polymetallic deposits in the area, combined with the geological characteristics of the mineral deposits, the authors consider...
RELATIONSHIPS BETWEEN COPPER MINERALIZATION AND THE DUCTILE SHEAR ZONE IN THE KALAXIANGEER HALASU COPPER DEPOSIT IN THE ALTAY AREA, XINJIANG
LI Hao-bin, WEN Chang-shun, WANG Zhi-ping
2007, 13(2): 141-149.
Abstract (235) HTML (116) PDF (378KB)(10)
Abstract:
The Kalaxianggeer Halasu copper deposit is situated in the eastern segment of the southern margin of the Altay metallogenic belt.Analysis of the structural deformation in the copper deposit shows that the brittle-ductile shear zone in the copper area has a certain controlling effect on mineralizatio...
BASIC CHARACTERISTICS OF THE YANSHAN MOVEMENT IN NORTHEASTERN SHANXI -A SUMMARY OF REGIONAL SURVEY OF THE 1: 250000 YINGXIAN COUNTY SHEET
ZHAO Zhen-xiang, DU Jin-feng
2007, 13(2): 150-162.
Abstract (474) HTML (366) PDF (619KB)(9)
Abstract:
The Yanshanian crustal activity in northeastern Shanxi was intense and frequent and underwent a process of extension→transpression→uplift and magmatism.The early stage of the Yanshan movement generated an Early Jurassic downfaulted basin and a Middle Jurassic compressional-downwarped coal-accumulati...
FAULT DISTRIBUTION PATTERNS OF THE LUXI BLOCK, SHANDONG, AND MESOZOIC SEDIMENTARY-MAGMATICSTRUCTURAL EVOLUTION SEQUENCE
ZHANG Xi-ming, ZHANG Yue-qiao, JI Wei
2007, 13(2): 163-172.
Abstract (295) HTML (119) PDF (385KB)(21)
Abstract:
Faults in the Luxi block have two different distribution patterns:one is the radiate distribution pattern, and the other is the concentric circular distribution pattern, with faults encircling the core of the block basement.The former is composed of NW-striking, steep-dipping, basement dextral ducti...
MICRO-EARTHQUAKES IN THE SHIZIGOU OILFIELD, QINGHAI, AND THEIR GEOLOGICAL SIGNIFICANCE
FENG Mei, AN Mei-jian, WANG Xiao-feng, MA Yin-sheng, JIANG Rong-bao, LI Li
2007, 13(2): 173-178, 172.
Abstract (203) HTML (128) PDF (319KB)(6)
Abstract:
A large number of high-quality seismic data are recorded in the Shizigou oilfield of the western Qaidam basin by monitoring micro-earthquakes for more than one year.After processing and analyzing these data, the authors find that micro-earthquakes occur relatively frequently in the study area and ar...
DEEP-SEA HYDROTHERMAL ACTIVITY: A HOT RESEARCH TOPIC
