2011, 17(1): 15-26.
Abstract (276) HTML (162) PDF (758KB)(29)
Abstract:
In WFSD-1 borehole of the Wenchuan earthquake fault scientific drilling project, we conducted relative temperature gradient high-precision measurements and obtained large numbers of field data. In this paper, the friction residual heat temperature measuring method is discussed in detail and the posi...
ANALYSIS UPON DYNAMIC RANGE AND MONITORING CAPABILITY OF WFSD DIGITAL SEISMIC NETWORK OF THE LONGMENSHAN FAULT ZONE
MA Xiu-min, PENG Hua, JIANG Jing-jie, PENG Li-guov
2011, 17(1): 27-40.
Abstract (295) HTML (95) PDF (1305KB)(10)
Abstract:
After the 5.12 earthquake in Wenchuan, the temporary digital seismic network has been layout in time in Longmenshan fault zone in order to monitor earthquake trends and probe into the large-scale tectonic stress field activity. Digital seismic network is made of 11 digital seismic instruments, and w...
REMOTE SENSING STRUCTURE ANALYSIS ON THE STRUCTURAL PROCESSES OF WENCHUAN AND YUSHU EARTHQUAKES: ANALYSIS OF AREA DANGEROUS OF EARTHQUAKE
LI Fang-quan
2011, 17(1): 41-54, 78.
Abstract (273) HTML (130) PDF (987KB)(9)
Abstract:
The earthquake is an deformation and displace of enveloping rock in crust. A succession earthquake in the same belt represents some diastrophism (crustal movement). viz. an earthquake is a "Seismic-Structural Event". The dangerous of seismic area in China for the past 20 years were predicted tentati...
ANALYSIS AND THINKINGS ABOUT THE ORIGIN AND BACKGROUND OF 2010 YUSHU EARTHQUAKE
GE Xiao-hong, WANG Min-pei
2011, 17(1): 55-63.
Abstract (259) HTML (124) PDF (1140KB)(14)
Abstract:
The 2010 Yushu earthquake, originated in Qinghai, struck on April 14, 2010, and registered a magnitude of MS 7.1. This paper discusses the origin and background of the earthquake and gives some advices about post-disaster reconstruction. Considering the geotectonic settings, the authors attributes t...
APPLICATION OF THE ETA-TYPE TECTONIC SERIES SUGGESTED BY LI SI-GUANG TO EARTHQUAKE PREDICTION
XU Dao-yi, SUN Wen-peng
2011, 17(1): 64-73.
Abstract (261) HTML (221) PDF (304KB)(11)
Abstract:
The eta-type tectonic system was suggested by academician Li Si-guan more than 70 years ago, and two great eta-type tectonic systems have been described by him: one is located in Qinhai-Xizang (Tibet) -Yunan-Burma-Indonesia (QXYBI), and the another is Western part of North America (WNA). Recently th...
DEVELOPING LI SIGUANG'S SCIENTIFIC THOUGHT ON EARTHQ
LI Fang-quan

Abstract (301) HTML (96) PDF (105KB)(14)
Abstract:
Some useful viewpoints on earthquake forecasting, based on Prof. Li Siguang 's important speeches and instructions, are presented in this paper in combination with authors'own experience and understanding. Those can be summarized in the four aspects as follows. The existence and change of earth stre...

Abstract:
The major progress and achievements obtained in the geological survey within the extent of the 1: 250000 Darlag and Jigzhi Sheets include: 1) Established the stratigraphical framework of the Bayan har Group and made a detailed analysis of the basin sedimentary filling sequences and the tectonic sett...
SEDEX DEPOSIT GENESIS OF THE Pb-Zn DEPOSITS IN THE NORTHEASTERN MARGIN OF LANPING BASIN IN YUNAN: EVIDENCE FROM MINERALOGICAL AND SULFUR ISOTOPIC STUDIES
HUANG Yu-feng, CAO Dian-hua, WANG Zhi-jun, LI Yi-ke, WANG An-jian
2011, 17(1): 91-102.
Abstract (267) HTML (115) PDF (977KB)(6)
Abstract:
A series of lead-zinc deposits such as Qingdianwan, Caizidi, Jinshantao and so on, which are situated in the Upper Triassic Shizhongshan Formation (T3s) at the Weixi-Qiaohou fault belt, northeast of Lanping Basin. The genesis studies of these lead-zinc deposits are relatively superficial.. In this p...
ENVIROMENTAL CHANGES RECORDED BY POLLEN SINCE MID TO LATE HOLOCENE IN HUITENGXILE LAKE, LNNER MONGOLIA
