2014, 20(1): 1-15.
Abstract (256) HTML (145) PDF (3158KB)(13)
Abstract:
Based on systematical analysis of regional metallogenic regularity of gold polymetallic deposits in Hainan Island, multivariate favorable geological evidences such as strata, structure, magmatic rock, aeromagnetic, geochemical exploration, and remote sensing data were analyzed and extracted. With th...

Abstract (383) HTML (193) PDF (2568KB)(23)
Abstract:
This paper focuses on a typical section of fault-bend fold in Kuqa foreland basin, by use of the shear fractures data measured in different structural position of the outcrop, and the fractures development laws are analyzed and then development models of the shearing fractures in fault-bend fold in ...
ACTIVITIES OF PALEOGENE FAULTS IN LANGGU SAG, JIZHONG DEPRESSION
ZHANG Dan-dan, DAI Jun-sheng, ZOU Juan, WANG Ke
2014, 20(1): 25-35.
Abstract (205) HTML (109) PDF (3413KB)(16)
Abstract:
By calculating the fault throw index and growth index of the active faults in Langgu sag, Jizhong depression, the fault throw figures and fault growth index figures of this sag in each geological time were drawn out. Research showed that Daxing fault had different activities at different locations. ...

Combining with logging data analysis, the author studied the sedime...
GENESIS AND SOURCES OF NON-CONVENTIONAL WATER SOLUBLE METHANE GAS IN GUSHI SAG
LIU Jian-chao, ZHANG Lin, WANG Xing-yun, BAI Jian-feng, FENG Long
2014, 20(1): 61-69.
Abstract (166) HTML (102) PDF (1595KB)(11)
Abstract:
The genetic types of water soluble methane gas in Gushi sag in Weihe Basin were studied. Research on carbon isotope δ13C1 and content of heavy hydrocarbon in water soluble gas methane showed that the genetic types of water soluble methane gas in different formations were different. Water soluble gas...
QUANTITATIVE EVALUATION OF CRUSTAL STABILITY ALONG THE BAOSHAN-RUILI SECTION OF DALI-RUILI RAILWAY AND ITS ADJACENT REGION
GUO Chang-bao, ZHANG Yong-shuang, QU Ke, XIONG Tan-yu, FU Xiao-xiao, DU Yu-ben
2014, 20(1): 70-81.
Abstract (204) HTML (97) PDF (4409KB)(26)
Abstract:
The Dali-Ruili Railway is located near the India and Eurasian plate's collision belt, where the geologic structure conditions are very complicated. The railway planning and constructions are restricted by the complex engineering geological problems related to the crustal stability, such as active fa...
