Abstract (203) HTML (80) PDF (1248KB)(11)
Abstract:
Copper-nickel deposit of Tudun which is located on the Huangshan-Jingerquan copper-nickel mineralization belt in East Tianshan area is controlled by magmatism and tectonic action. To further prospect the minerals of this region, using thermal infrared data of Aster, the authors quantitatively retrieve SiO2 content in the rocks from emissivity data by inversion algorithm simulated from different band ratio combination. According to the inversion map view, we extract many large silicified fault zones. Combining with the information of the faults, based on visible -near infrared bands, we obtain the fracture distribution of the study area. Principal component analysis and threshold segmentation were used to enhance the spectrum and space information and extract the iron-stained and hydroxyl alteration information. Through comprehensively analyzing the linear structure, remote sensing alteration information, rock mass distribution characteristics, regional geochemical information and known deposits, six metallogenic prospective areas are delineated.

Abstract:
Energy exploration, rock identification, minerals mapping, and metallogenic delineation are the main directions of hyperspectral technology. The spectral information of visible, near-infrared and short-wave infrared can be obtained under the same platform in CASI/SASI airborne hyperspectral data which has higher spectral resolution and spatial resolution than multi-spectral data and spaceborne hyperspectral data and gains broader use in extraction of mineral alteration information. The paper studies the key technologies of mineral extraction and develops the flow of mineral mapping with CASI/SASI airborne hyperspectral data by extracting mineral alteration information such as chlorite, muscovite, montmorillonite, and illite in Liuyuan, Gansu.

Abstract:
This article selects Bangbangnaibeiiiqieer that is located in China's major ore concentration area in Inner Mongolia as the research area and proposes an enhanced extraction of alteration information using remote sensing, which extracts alteration information first, and then uses topographic correcting. Firstly, the area is divided according to landform, topography and rock character, and then the extracted alteration information is corrected based on topography; Secondly, alteration information is extracted combing geological data, geophysical prospecting data and geochemical exploration data. Finally, metallogenic prediction is built. This new study is better than previous study, because it can display alteration information obviously, eliminate the effects of topography and rock character, and offer a more accurate evidence for further mineral investigation.

Abstract:
The Jijiawa gold deposit in Henan Province, located at the southern margin of North China Craton, is a small-scale deposit in the Xiongershan goldfield. Gold ore bodies are hosted within and have consistent attitudes with the NNE and/or SN trending fault fracture zones, which in turn strictly controlled the shapes and occurrences of the ore bodies. A systematic whole-rock geochemical survey on fracture zones F1 and F7 in the adjacent region of the deposit is carried out, and several high strength Au anomalies controlled by the fractures have been confirmed. After drilling construction, gold ore bodies have been discovered. The statistical analysis on the primary halos of the drilling cores further indicates that the ore bodies extend downwards in some degree. The drilling construction also reveals gold ore bodies in depth developing along the fractures. In terms of calculation on resource reserve, the discovered deposit is medium-sized in scale. There are lots of mineralizing fractures in the adjacent regions of the Jijiawa deposit, in which the primary halos have following characteristics. The front-halo elements are well-developed, but rear-halo elements aren't. Moreover, the front-halo elements, main ore-forming halos and rear halo elements are developed at depth. As a result, the new discovered gold ore bodies extend at depth. We thus suggest that there are good ore prospects in the adjacent regions of the deposit.

Abstract:
Xincheng gold deposits located in the footwall (fault gouge) of the Jiaojia fault store consist of pyrite phyllic cataclastic zone and pyrite phyllic granodioritic rock band fragmentation. By analyzing the characteristics of the main ore body-NO.ⅠandⅤ, evaluating the conditions for mining, the engineering geological condition of deposits is easy, and mined-out area has little influence on the stability of the rock mass in the deposit. Based on the environmental geological conditions of the deposits, it is favorable for mining.

Abstract (160) HTML (108) PDF (1528KB)(15)
Abstract:
The Yuanba gas field located in the northwestern Sichuan Basin contains the original in-place gas volume of more than one hundred billion cubic meters identified in marine strata. The Upper Permian Changxing Formation as the main gas reservoir for the field is characterized by an abundance of H2S gas, and is typically buried at deep depths where it is subjected to high temperatures and pressures, gas and water distribution systems are intricate and engineer geology conditions are complicated within it. The dolomites of reef and shoal facies in the Changxing Formation have been regarded as high-quality reservoirs, which exhibits high porosity and permeability, high reservoir heterogeneity, considerable gas production capacity. The aim of this study is to improve the understanding of the dolomite origin using the carbon and oxygen isotopes and the high-quality reservoir formation at deep and ultra-deep depths by analyzing strong correlations in reservoir petrography, depositional facies, diagenesis and fracture development system in detail. The research shows that platform-margin reef and shoal facies in the study area are the most favorable facies belts controlling high-quality reservoir formation because reservoir rock types and spatial geometry are generally determined by depositional characteristics. Dolomitization and dissolution is significantly helpful in increasing reservoir porosity. Multi-history fracture system appearing tectonic in originis very constructive to improve reservoir permeability. It is possibly fair to say that the high-quality reservoir formation in the Changxing Formation was determined by synthetic configurations and dynamic interplays between multiple geological processes and factors.

Abstract:
The Yong-3 fault block in Dongxin is a complicated reservoir with multi-layers, medium and high permeability, thin oil. The main oil-bearing layer is Shahejie Formation. According to the 3D seismic interpretation, with choosing the appropriate material, setting boundaries, determining time and loading stress, physical modeling experiments of the structural development in the Shahejie Formation, Paleogene in the study area are conducted on the basis of similarity theory for the uncertainty of structural shape and the genetic mechanism. The result makes the representation of basic fracture characteristics come true to validate the seismic interpretation. It also shows that the multi-phase structural evolution history can be divided into NNE-SSW extention, NNE-SSW and NW-SE extension, dextral-slipping and diaper. Mechanically, the tectonic evolution in the study area is controlled by intense extension and the fault depression of Dongying sag and the right-lateral strike-slip of Tanlu fault zone.

Abstract (226) HTML (104) PDF (1314KB)(9)
Abstract:
The Tianshui Forging Machine Plant Landslide in Gansu Province happened on August 11, 1990 with a volume of 1.4×106 m3. It is a loess interface landslide occurring along the loess/mudstone interface. The landslide body is mainly composed of secondary loess, and the slip bed is mainly composed of Quaternary loess and Neogene mudstone. The landslide is controlled by the double-layered structure of the slope in area, being induced by some factors such as engineering excavation, rainfall and irrigation. The research on the deformation mechanism and evolutionary process of the landslide based on geological survey and engineering drilling shows that the formation process can be divided as follow: the formation period of high and steep side slopes; the landslide incubation period; sliding surface through critical period; landslide falling and accumulating period; landslide revival and deformation period. Field investigation and engineering drilling indicate that the landslide is unstable at present. It can most likely revive and slide again if there is earthquake or heavy rainfall. The results can provide theoretical basis for the disaster warning of this kind of landslide.
