Polymetallic iron ore sulphate deposits of marine volcanic rock have been developed in the Fangniugou area, Jilin Province, China, but the division of volcanic ore-bearing strata has not been specifically elucidated and there is disagreement about the division. The sampling and SHRIMP U-Pb zircon dating of volcanic rock for Daheishan in the Fangniugou area and the northeast slope of the Duanjiadian were described. The volcanic rock formation period and recorded the volcanic events in the Daheishan mountains were systematically researched. Two samples of high-precision U-Pb zircon dating were used to represent the volcanic rock fomation period of the Late Silurian. The measured data reflect that multiple volcanic activities occurred during the Middle Silurian, Early Silurian, Middle Ordovician and Silurian, and Late Ordovician, probably matching volcanic events in the Songnan Basin identified from zircon dating. At the same time, it is confirmed that a controversial "conglomerate of Daheishan" did in fact develop in the Late Silurian, and those sections of both the Dazigou and Xinlitun-Taoshan with graptolite had been reversed. © 2014 Central South University Press and Springer-Verlag Berlin Heidelberg.

With the development of Internet, basic information services can no longer fulfill some customers' requests, which requires information service brokers to provide value-added services to improve their information service quality. Based on the web service architecture, this paper constructs a value-added service model of mining right information from the perspective of information value-adding, and describes the information value-adding process. In this paper, we also illustrate different levels of mining right information service workflows. The proposed value-added services of mining right information are initiative and two-way services, which can enhance information value to meet customers' information requests. © 2010 IEEE.

The superimposed basin is of poly-phase differential structural deformation controlled by key tectonic stages. Five tectonic reform stages, that is mid-Caledonian, Late-Caledonian-Early Hercynian, Late-Hercynian, Indosinian-Yanshanian, and Himalayan, maybe recognized from deformation analysis in the Tarim basin. The development and evolution of the Tarim basin are affected by the main tectonic reform stages. According to the analysis of known oil-gas belts of northern Tarim uplift, mid-Tarim uplift and Kuqa depression, it is indicated that the huge marine carbonate paleo-karst oil-gas pools are controlled by the faulting and folding, uplifting and erosion, and karsting during the period of the Paleozoic tectonic reforms. A large number of hydrocarbon accumulation in the foreland fold-thrust belt are controlled by the Meso-Cenozoic tectonic reforming. All these known hydrocarbon accumulation zones are finalized at the Late-Himalayan movement, forming hydrocarbon accumulation model of the poly-phase reform-late-stage finalization composite tectonics. Analyzing the poly-phase differential structural deformation, an evaluation and strategic selection of oil-gas resources in the new exploration areas of the Tarim basin have been made based on the above-mentioned model. It is proposed that the best new exploration regions are Bachu uplift, Maigaiti slope and foreland fold-thrust belt on the west Kunlun Mountain footwall. And the eastern Tarim, Tangubasi depression and Awati fault-depression are of favorable oil-gas exploration prospects.

The salt beds of the Middle-Lower Cambrian are widespread in the middle-west parts of the Central Uplift and adjacent areas, the Tarim Basin. This paper presents the results of seismic interpretation and drilling data analysis, which discovered that the salt beds were formed in an old geologic age, deeply buried, with relatively small scaled flowing and gathering and uneven distribution. As the regional detachment layers, the salt sequences considerably control the structural deformation of the up-salt Paleozoic, forming a series of hydrocarbon traps. In due course, the salt beds of the Middle-Lower Cambrian provide excellent cap rocks and trap conditions; thus the value of exploring hydrocabon reservoir in the target strata of the sub-salt Sinian-Cambrian is greatly increased. Research has shown that the salt-related structures of the Middle-Lower Cambrian in the area mainly exist in the form of salt pillow, salt roller, up-salt anticline, salt diapir, assemblage of the salt arch and up-salt fault-block, assemblage of basement fault and salt anticline, assemblage of the basement fault-block and salt dome, assemblage of salt detachment and fault-related fold, and assemblage of basement fault-block, salt arch and up-salt imbricated thrusts. The evolution and deformation mechanisms of the salt-related structures are controlled largely by basement faulting, compressional shortening, plastic flowing and gathering, superstratum gravitation, and up-salt faulting and detaching. They are distributed in rows or belts along basement faults or fault block belts. © 2012 Science China Press and Springer-Verlag Berlin Heidelberg.

Through testing single-axial compressive strength, modulus of elasticity and Poisson's ratio of rock samples collected from outcrop areas in Tarim basin, including Kuqa depression, Keping uplift and Bachu uplift, the section showing the rock mechanics characteristics of the Tarim basin is completed. The comprehensive analysis of stress-strain curves of the samples shows the influence of the rocks structure on their mechanics characteristics, which offers accurate experiment data for analyzing differential layered and detachment structural deformation. Based on the seismic reflection profile, taking the Selibuya faulted-anticline which is the boundary fault of Bachu area as example, geometry deformation style and mechanism are analyzed. Structural recovery is based on mass-spring equation, and strain analysis based on this fact that the sandstone of Silurian and Devonian are capable layers. The research result indicates that, because its rock mechanics properties is far higher than adjacent formations, the Silurian and Devonian sandstone dominate the distortion of overlying strata and inhibit the vertical deformation of deep layers. Profile explanation result reveals that the gypsum within the Aertashi Formation at the bottom of the Paleogene and lower-middle Cambrian acts as the detachment layers, corresponding to the rock mechanics parameters obtained from laboratory. Combined with deformation analysis and stress-strain analysis of Selibuya faulted-anticline, it can be concluded that, for the same structure under the same stress field, structure deformation is not only controlled by the mechanical property of rock, but also decided by its structure position and deformation behavior.
