^87Sr/^86Sr, δ^18O and δ^13C ratios of calcite, dolomite, gypsum filling vugs and fissures in marine carbonates and their host rocks from the Sinian to the middle Triassic, are employed to trace the possible source and migration path of key fluids related to development of hydrocarbon, hydrocarbon preservation condition are then discussed further. Comprehensive research, based on the paleo-fluid, the property of formation water and the deformation intensity etc., indicates that the preservation conditions in the Shizhu synclinorium zone and Fangdoushan anticlinorium zone are the most predominant in the central Yangtze. Three sets of fluid systems in the Shizhu synclinorium zone are identified. Little fluid exchange occurs between the upper-middle fluid system and the lower fluid system, so two independent preservation units have developed. Both the Permian and the Triassic in the upper preservation units and the Dengying Formation of the Sinian and the lower Cambrian in the lower preservation units have good preservation conditions. The preservation condition in the lower association （Z-S） located in the Huaguoping synclinorium zone in the western Hubei and Hunan is better than that in other tectonic units, where the fluids in the lower association migrated vertically across strata when the fluid isolating intervals were destroyed, the regional seals are absent and the conditions for the preservation of hydrocarbon accumulations are totally destroyed. The preservation condition is increasingly more favorable from the western Jiangxi and Hunan to the western Hubei ＆ eastern Chongqing on the whole.

The Qiangtang basin is located in the north of Qinghai—Tibet plateau and sandwiched by Nianqingtangula continental block and Kekexili\|Bayuankal continental block. Its southern boundary is the Bangongfu—Nujiang suture zone and its northern boundary is the Xijinwulan\|Jinshajiang suture *** basement of Qiangtang basin is composed f metamorphic rock of Proterozoic age, which can be divided into two parts. The competent lower part with isotope age of 2056～2310Ma experienced multi\|stage deformation and the soft upper part is dated 1111～1205Ma. Within the basin, it groups into Northern Qiangtang Depression, Central Rise and Southern Depressions and are complicated by a number of subdepressions and *** strata of Middle Devonian\|Tertiary are overlain on the basement and composed of marine carbonate rocks, clastic rocks and terrestrial sandstone and conglomerate. Several sets of faults and folds have developed in the cover sequence and the deformation is very strong, characterized by orientation, zonation and equidistance in space and by diversity and disharmony in the profile. The major deformation occurred in Yanshan\|Himalayan period.

Preparation and Photochemical Behavior of a Cationic Azobenzene Dye-Montmorillonite Intercalation Compound

引用

Journal of Wuhan University of Technology(Materials Science) 2007年第3期22卷 466-469页

作者：万涛 College of Materials and Chemistry & Chemical Engineering Chengdu University of Technology

Montmorillonite/cationic azobenzene dye（p-（δ-triethylammoniobutoxy）-p＇-methyl- azobenzene bromide） intercalation compounds were prepared by the conventional ion exchange method. As compared with that of pure cationic azo-dye, the thermal stability of the intercalated dye was greatly enhanced, and the absorption band corresponding to azobenzene group in intercalated dye shifted towards longer wave length by 38 nm. This could be ascribed to the strong conjugation of cationic azo-dye supramolecular order structure（J cluster） confined in a nanoscale space of montmorillonite interlayer gallery. UV/vis spectra data show that the intercalated azo dye in the montmorillonite interlayer space exhibited reversible trans-to-cis photoisomerization and daylight cis-to-trans back reaction. FTIR indicates the successful intercalation of cationic azo-dye into the montmorillonite interlayer.

Origin of CO_2 in natural gas from the Triassic Feixianguan Formation of Northeast Sichuan Basin

引用

中国科学：地球科学英文版 2010年第5期53卷 642-648页

作者： HUANG SiJing, HUANG KeKe, TONG HongPeng, LIU LiHong, SUN Wei & ZHONG QianQian State Key Lab of Oil and Gas Reservoir Geology and Exploitation, Institute of Sedimentary Geology, chengdu University of Technology, chengdu 610059, china 1. State Key Lab of Oil and Gas Reservoir Geology and Exploitation Institute of Sedimentary Geology Chengdu University of Technology Chengdu 610059 China

The natural gas from the Triassic Feixianguan Formation of Northeast Sichuan Basin contains high H2S whereas relatively low CO2 concentrations and the CO2 display high δ13C values (ranging from -5.81‰ to 3.3‰ (PDB)). This seems to contradict the conventional wisdom that TSR should be a primary source of CO2 in natural gas from the Feixianguan Formation. In contrast, many authigenic calcite samples from these sites display very low δ13C values (ranging from -18.4‰ to -10.3‰ (PDB)). This suggests that the carbon from TSR source dominated the formation of calcite whereas the carbon from inorganic source came into CO2 in natural gas. In order to assess the origin of CO2 from these H2S-rich sites, we have calculated the relative contributions of organic and inorganic carbon sources to the CO2 and authigenic calcite. The organic carbon source possibly originated from TSR, whereas the inorganic one might be generated from marine carbonates dissolution. This calculation is based on the carbon isotopic compositions of CO2 and authigenic calcite as well as an isotopic mass balance. The results show that the contribution of organic carbon source to the CO2 is only 2%, whereas that to authigenic calcite is as high as 43% on average. Such results combined with thermodynamic evidence indicate that the isotopically light CO2 produced by TSR process may contribute to authigenic calcite precipitation during burial diagenesis. Distinguishable from Ordovician reservoir of Tarim Basin, Feixianguan reservoir of Northeast Sichuan Basin experienced rapid tectonic uplift due to Yanshanian movement after TSR occurred. Such tectonic event could induce temperature decrease and further promote carbonates dissolution. During these processes, secondary porosity has developed in Feixianguan carbonate reservoirs. Therefore, much attention should be paid to the structural highs in search of high quality carbonate reservoirs.

UPLIFT AND DENUDATION AT SOUTHEAST MARGIN OF TIBET PLATEAU IN QUATERNARY

引用

地学前缘 2000年第S1期7卷 306-307页

作者： Wang Guozhi,Wang Chengshan,Liu Dengzhong[WT5,5”BX](chengdu Institute of Technology,chengdu 610059,china)

The southeast margin of Tibet plateau mainly consists of the Western Yunnan plateau (WYP). The uplift and denudation at the southeast margin of Tibet plateau can be represented by that of the WYP. Based on the uplift of ancient plantain surface, river terrace and sedimentary response in peripheral basins of the WYP, suggest that the WYP experienced a rapid uplift and denudation in Quaternary. The WYP have been uplifted about 610～700m, and eroded away about 1095～1600m since Quaternary, average denudation rate reach 0 68～0 94mm/a. Uplift rates in different time interval were calculated according to river terrace. Relations between WYP and Tibetan plateau are discussed further..The Yinggehai basin located at the south termination of the Red River fault, it is the younger (mainly Neogene) pull\|apart basin, which developed at releasing bend of the Red River right\|lateral wrench fault. Since the Neogene, the subsidence center of the Yinggehai basin shifted southward and, connected with the Southeast Hainan basin. Both basins collected large amounts of the Holocene and Quaternary deposits of marine origin. They are peripheral marine basin of the WYP.. Silicate clastic sediments in both basins have been large supported from the WYP into both basins through the Red River system. The total volumes derived from the WYP in the Neogene and Quaternary is 2 8004×10 14 t(1 and 5 1206×10 14 t. The sedimentation rate in Yinggehai basin rose from 0 52mm/a in the Neogene to 1 39mm/a in the Quaternary. The facts that accumulation volume and sedimentation rate rose greatly after the Neogene, suggested a rapid uplift in the WYP. The rapid uplift was responsible for the unconformity between the Neogene and Quaternary. Elevation of ancient planation surface,and river terrace supported the rapid uplift of the WYP also. The ancient planation surface was elevated from 2500～2600m to 3000～3200m during Quaternary, seven terraces in Tue can be traced through the field area in elevation from 20 5

CHARACTERISTICS OF ALKALINE VOLCANIC ROCKS OF PLIOCENE IN THE WESTERN PART OF HONGHE FAULT ZONE

引用

地学前缘 2000年第S1期7卷 270-271页

作者： Wang Guozhi,Huang Yongjian,Ma Renze,Wang Chengshan [WT5,5”BX](chengdu University of Technology,chengdu 610059,china)

A set of pull\|apart basins were formed along the Weixi—Qiaohou right\|lateral slip shear zone of the western part of Honghe fault zone during the period from Miocene to Quaternary.A rock suite of alkaline basalt\|trachyte\|leucite phonolite is distributed in the Pliocene basin developed in the middle and northern parts of the fault. The location of these rocks and the features of the basin indicate the close relationship between the rock suite and the strike\|slipping.. The sedimentological and chronological evidences prove that Dianxi plateau uplifted quickly in the Pliocene. We can get the information about the plutonic process of the uplift of the plateau from this alkaline rock association. There are mainly olivine\|pyroxene\|trachyandesite and biotite\|trachyte in the rock association. The rocks are often of porphyritic texture and block or semi\|directional flowage structure while the matrix is of trachytic or microcrystalline texture. The phanerocrysts are diopsidic augite, rimpylite, biotite and perthite (olivine sometimes can be seen). The matrix are made up of alkaline feldspar microcrystalline (30%～50%), short\|grained diopside (10%～15%), light\|colored volcanic glass (0～15%) and some magnetite, while feldspar microcrystalline in some rocks are arranged directionally. And there are sharp\|edged or round pyroxenite enclaves and hemicrystalline of short grained sinaite, biotite sinaite and felsic breccia in the trachyte, with good demarcation line. The pyroxenite enclaves in the trachyte are of different size, and the size of the biggest ones are 10cm or so with the characteristic of plastic yield flowing. Sinaite hemicrystalline may come from the older intrusions of Pliocene and Eocene epoch.
