Basal synthem is the Taishan mountain group in archaean, is mainly the gneiss; The paleozoic synthem besides the regional lost stratas: Upper Ordovician, Silurian-Devonian and Lower Carboniferous, other stratas have the distribution, divides into Cambro-ordovician and Permo-Carboniferous two structure subgroups. Cambro-ordovician is a set of carbonate construction, Permo-Carboniferous system is a set contains the coal clastic rock deposition; In the mesozoic synthem lost Upper Triassic and Upper Crataceous ,growth Middle-Lower Triassic and Middle-Lower Jurassic and Lower Crataceous three structure subgroups, main growth varicolored land facies clastic rock, discovered rich fossil data such as cryptogam ,Ostracoda and Chareae and so on.

Volcanic gas reservoirs of low permeability in the carboniferous of a basin are characterized by deep burial depth, complex genesis, many types, wide distribution and non-evident expressions in three-porosity log curves, as well as the variedvalues of density and compression wave of main four volcanic gas reservoirs (such as the basalt, andesite, dacite and rhyolite). So a number of effective methods based on three porosity log data cannot work in identifying the volcanic gas reservoirs of the carboniferous of the basin.
石炭系火山岩的低渗透气藏具有的埋藏深、成因复杂、类型多、分布广、三孔隙度曲线响应特征不明显等特点,并且主要的四种火山岩气藏:玄武岩、安山岩、英安岩、流纹岩的密度和纵波时差测井值差别较大,因此使基于三孔隙度测井资料的一系列识别气层的有效方法在该盆地石炭系火山岩气层的识别中无明显效果。

Of the five stages deformation, the exact ages of the (2) and (3) were determined by 40Ar/39Ar method as 290 and 259 Ma respectively.2. New results on the metamorphic belts and associated metamorphism of the Xiaopu metamorphic rocksBased on detailed microtextural observations and occurrence of typical metamorphic minerals, five metamorphic belts in the Xiaopu metamorphic rocks are identified. From the north to the south, they are biotite belt, garnet belt, staurolite belt, andalusite belt, and sillimanite belt. I suggested that the metamorphic belts occurred in the Xiaopu area belongs to the high temperature/low pressure series, may have resulted from the later Permian crust extension at ca. 290 Ma.3. I suggest that there may have been a Carboniferous backarc basin along the southern slope of the Harlik Mountain.Detrital Zircon SHRIMP U-Pb dating indicated that the sedimentary age of the Julideneng formation lithic sandstone must be later than late Devonian, most likely is Carboniferous rather than previously thought Precambrian. Analyses on its geologic setting, location of provenance, and sedimentary environment suggest the Carboniferous strata may form in a lagged backarc basin bounded by backarc uplifts.5. Reconstruction of the post-Paleozoic tectonic evolution history of the Harlik MountainThe tectonic evolution of Harlik mountains since the Paleozoic were reconstructed as followings:(1) arc-affinity magmative activities occurred during the middle-Ordovician to early-Silurian;(2) the middle-Silurian to late-Devonian was a back-arc uplift stage;(3) back-arc extension featured the Carboniferous period;(4) post-collisional extension and/then compression during Permian;(5) at the Mesozoic, differential uplift developed; and (6) the late Cenozoic is the intra-continental re-orogen stage.6. Primary estimation of the crust shortening is madeThe folded pre-Mesozoic strata were used to estimate crust shortening along the Harliknanshankou-Koumenzi, Shichengzi-Baishitou, and Qincheng-Xiaopu sections. Their shortening ratios are 16.2%, 19.8%, and 20.1% respectively corresponding crust shortening are 4.3, 9, and 11.3 km.

A good many mico-landblock of the early Neoproterozoic-Cambrian volcanic rock that distribute in the Tianshan orogenic belt and on its both sides, and the Carboniferous-Permian volcanic rocks that widely distribute in the Tianshan and adjacent regions are selected for subject investigating in this paper. Renewing the ocean-land format and ocean-land conversion process of Tianshan orogenic belt in the Paleozoic is the masterstroke for this paper. On the basis of detailed field investigation, many subjects, such asregional lithology、geochemistry、structural geology、volcanic sedimentology geology、sotope geochronology and synthesis analysis study of geophysics data, are adopted as instrumentality in the paper, this study lays emphasis on the formation, evolution and dynamics of early Neoproterozoic-Cambrian and Carboniferous-Permian volcanic rock in the Tianshan and its adjacent regions to find out Carboniferous-Permian volcanic rock property, eruptive sequence, time and space distribution characteristics, to resume and reconstruct evolution process of Carboniferous-Permian volcanic rock, and to explore connection of magmatism process and lithosphere stretching action of neopaleozoic ocean-land transformation in the Tianshan region.
