1998, 4(2): 39-44.
Abstract (237) PDF (283KB)(7)
Abstract:
In the Dabeiwu gold field occurs aλ-type structure composed of the NE-trending major shear fault and the NEE-trending splay compressive fracture zones,which developed in the regional ductile-shear zone,constituting the main ore-bearing structures.The growth and evolution and the difference in deform...
STRUCTURES OF KANGGUER GOLD DEPOSIT IN THE-EASTERN TIANSHAN MOUNTAINS,XINJIANG
Ma Tianlin, Sun Liqian, Xu Xingwang
1998, 4(2): 45-52.
Abstract (360) PDF (354KB)(8)
Abstract:
Kangguer gold-polymetallic deposit with associated copper,lead,zinc and silver,lying south of the Tu-Ha basin in the eastern Tianshan Mountains,occur in the gigantic Qiugemintashi-Huangshan ductile compressional belt.The formation of the deposit is closely related to the evolution of this ductile co...
RELATION BETWEEN THE FAULTING AND GOLD-MINERALIZATION IN THE JIAOJIA GOLD DEPOSIT, EASTERN SHANDONG PROVINCE
Xu Gang, Zheng Daxing, Wen Changshun
1998, 4(2): 53-58.
Abstract (204) PDF (255KB)(8)
Abstract:
The gold ores were found to be distributed along the faults occurring in the Jiaojia goldfield,Eastern Shandong.The faults had undergone at least 3 stages of acitivyt,the first two being characterized by compresso-shearing, the thrid by tenso-shearing.Each individual of the ores can be correlated to...
STUDY ON GEOCHEMISTRY OF MAIN MICROELEMENTS OF ORE-BEARING STRUCTURAL BELT OF DABEIWU GOLD DEPOSIT,JIANGXI PROVINCE

1998, 4(2): 59-66.
Abstract (237) PDF (361KB)(14)
Abstract:
The Dabeiwu gold deposit located in the Fuliang county,Jiangxi province is controlled by the ore-bearing strata and the brittle-ductile shear zone.It lies in the south-west section of the brittle-ductile shear zone in which the tectonic deformation of rocks is the strongest.The variation of the cont...
TECTONIC-LITHOFACIES FEATURES OF GOLD DEPOSIT OF METAMORPHIC ROCK TYPE IN EASTERN SHANDONG AND ITS ORE-CONTROLLING
