STUDY ON REGIONAL MINERALIZATIONS AND ORE-FIELD STRUCTURES:BUILDING OF MINERALIZING TECTONIC SYSTEMS
CHEN Xuan-hua, CHEN Zheng-le, YANG Nong
2009, 15(1): 1-19.
Abstract (687) HTML (217) PDF (1289KB)(59)
Abstract:
Geological structures have a close dynamic coupling relationship with regional mineralization under the control of tectonic stress fields and tectonic movements. Different kinds of structures, such as faults, folds, ductile shear zones, and crust-mantle coupling structures, exert control of minerali...
GEOCHEMISTRY AND PALEO-TECTONIC ENVIRONMENT OF FENGYAN Pb-Zn ORE DEPOSIT IN MEIXIAN, CENTRAL FUJIAN PROVINCE
ZHANG Da, WU Gan-guo, DI Yong-jun, YU Xin-qi, PENG Run-min, HUANG Huo-jian
2009, 15(1): 20-35.
Abstract (218) HTML (115) PDF (1503KB)(14)
Abstract:
Pb-Zn-Ag ore deposit in Meixian, Youxi County is located at the south of the Zhenghe-Dehua pre-Cambrian metamorphic area, and geologically situated at Shouning-Hua' an sub-basement uplift zone in Eastern Fujian volcanic depression belt, east of the NE-striking Lishui-Haifeng fault. The ore-bearing b...
STRUCTURAL CONTROL OVER THE ORE IN HENGJIAN-GANGSHANGYING DEPOSITS IN XIANGSHAN ORE FIELD, JIANGXI PROVINCE
ZHANG Hong, CHEN Zheng-le, YANG Nong
2009, 15(1): 36-49.
Abstract (209) HTML (161) PDF (1668KB)(25)
Abstract:
The Hengjian-Gangshanying deposits are located in the north of Xiangshan collapse volcanic basin. Regionally the NE and EW striking faults and volcanic faults jointly exert control on the position of subgranitic porphyry and uranium deposits. Locations of subgranitic porphyry are obviously confined ...
APPLICATION OF ELECTROMAGNETIC MEASUREMENT TO GOLD DEPOSIT EXPLORATION IN GREENSCHIST BELT OF WESTERN SHANDONG
HUO Guang-hui, WANG Hai-qin, WANG Hong, WANG Yu-he
2009, 15(1): 50-55, 76.
Abstract (222) HTML (139) PDF (1317KB)(39)
Abstract:
In the Zhoujiazhuang gold deposit, Tai' an of Shandong Province, a high-resolution electric profile and reliable geological information have been obtained by using electromagnetic measurement, and hidden gold ores confirmed by drilling proof. The measurements show that the low-resistivity belts unde...
THE LATE MESOZOIC EXTENSION-SLIPPING-CONTRACTION OF THE ERLANGPING GROUP IN THE NORTH QINLING TECTONIC BELT, CENTRAL CHINA
ZHANG Hong-yuan, WANG Zong-qi, LIU Jun-lai, YAN Quan-ren, WANG Tao, YAN Zhen
2009, 15(1): 56-68.
Abstract (251) HTML (98) PDF (2391KB)(11)
Abstract:
The convergence belt between the Sino-Korea block and the Yangtze block was strongly deformed by intracontinental tectonomagmatic activity in the Late Mesozoic.In order to show details of the belt during the Late Mesozoic, we have carried out a series of analysis for the Erlangping Group on mesosmal...
DISCOVERY OF LATE MESOZOIC MAGMATIC ROCKS IN ORDOS ANCIENT CONTINENT NUCLEUS AND ITS GEOLOGICAL IMPLICATION
ZHENG Fan-shen, KANG Yi-qing, KANG Hong-zai, ZHANG Feng-yu, DI Yong-jun
2009, 15(1): 69-76.
Abstract (314) HTML (147) PDF (2011KB)(8)
Abstract:
In the ancient and stable Ordos continent nucleus, we found deep-seated indicator minerals diamond in a preliminary exploration, and basaltic magmatic rocks in the source area of anomaly of indicative of the minerals.This deep source magma mainly occurs as weak eruption or explosion, or fissure inje...
THE FORMATION MECHANISM OF THE NIHEWAN PALRO-LAKE AND ITS RELATIONSHIP WITH LIVING ENVIRONMENT FOR EARLY ANCIENT HUMEN
YUAN Bao-yin, TONG Hao-wen, WEN Rui-lin, WANG Yan-hua
2009, 15(1): 77-87.
Abstract (354) HTML (300) PDF (1451KB)(32)
Abstract:
The Nihewan Basin is located at northeast end of the Fen-Wei rift valley system, and constitutes an important part of it. At the beginning of Eogene an upwelling plume of soft mantle was developed in Hengshan-Datong region. It caused thinning of the crust and magma eruption. During 25~24 Ma the crus...
DISCUSSION ON THE FURTHER RESEARCH IN LOESS HYDROCOMPACTION
XU Ling, DAI Fu-chu
2009, 15(1): 88-94, 104.
Abstract (368) HTML (107) PDF (1326KB)(21)
Abstract:
Loess hydrocompaction has been discussed for a long time.During the 1960s ~ 1980s, with the application of SEM and mineral analysis, the micro-structure theory of loess hydrocompaction was developed and improved, but it has rarely been used in engineering numerical analysis because it failed to supp...
AEOLIAN ORIGIN OF THE RED EARTH TORMATION IN JIUJIANG CITY OF JIANGXI PROVINCE, CHINA :EVIDENCE FROM GRAIN-SIZE ANALYSIS
LI Jing-wei, QIAO Yan-song, WANG Yan, PENG Sha-sha
2009, 15(1): 95-104.
Abstract (306) HTML (196) PDF (1476KB)(8)
Abstract:
The Red Earth Formation in the middle-lower Yangtze River is an important pedostratigraphical unit in southern China.This formation is among the best geological records of Quaternary environment that bear information of climate changes for the subtropical zone of China.The study on the origin of thi...
