31. Geology: tectonics, is a mid - and late Paleozoic uplift of the land into the North China platform.

32. Wunan gold deposit is located in the active zone of northern margin of Tarimu plate, which concretely exist in the structure unit of triphibian edge in the late Paleozoic in southern Tianshan.

33. Within the petroleum domains, the hydrocarbon-bearing Paleozoic, Mesozoic and Neozoic sequences were superimposed in a basin.

34. In late Paleozoic, the western borderline belt of the basin were coastal basin located in passive triphibian margin.

35. In addition, Paleozoic primary reservoirs are preserved in prospective areas of Mesozoic and Cenozoic rift depressions and Upper Paleozoic coal measure.

36. The results indicate that there mainly develop a set of shallow marine shelf clastic sedimentary rocks and platform carbonate rocks during the Sinian-Lower Paleozoic(Lower Assemblage) period.

37. The Tianshan Mountains formed after the closing of the Late Paleozoic oceanic basin and the geomorphological features of the present mountains are the production of Late Cenozoic crustal movement.

38. Tarim basin is a huge superposed basin composed of Paleozoic cratonic basin and Meso - Cenozoic foreland basin.

39. Many fold systems constituted by the Precambrian Paleozoic platform structural layer and the endogenetic gold deposits controlled by those fold systems are formed in the Meso Cenozoic eras.

40. Jinzhou coal-series kaolin rock belongs to Paleozoic epizonal metamorphism rock series. The kaolinite is schistose and scaly shape.

41. The tectonite of Paleozoic in areal coverage appears the similar characteristic with that in outcrop area, and its cataclastic structure serves as an effective space for oil-gas accumulation.

42. The age of emplacement is at Upper Paleozoic Era from the result of isotopic age determination.

43. The Qiuling sediments - hosted disseminated gold deposIt'shanxiFormation and Yuanjiagou Formation of Upper Paleozoic.

44. Cambrian The earliest period of the Paleozoic era ,(www.Sentencedict.com) about 590 - 510 million years ago.

45. The Phanerozoic is divided into three eras — starting with the earliest, these are the Paleozoic, Mesozoic, and Cenozoic.

46. In the east part of the North China, there are potential carbonate source rock of sea facies of Lower Paleozoic and good coal formation source rock of Upper Paleozoic.

47. However, how are the prospects of Paleozoic marine oilgas in China?

48. Paleozoic carbonate buried hill reservoir in Nanpu oilfield is a pore - fracture dual media reservoir.

49. Myriapod animals were probably one of the invertebrate animal groups that first colonized the terrestrial ecosystem during Early Paleozoic.

50. There are distributed the transmutative rock in the Hills area of Taishan Montain, the limestone stratum of the Paleozoic in the middle and south of Shandong.

51. The Lower Paleozoic carbonates of Tarim Basin were marbleized locally due to the thermal effects of magma intrusions.

52. Of, relating to, or designating the geologic time, system of rocks, and sedimentary deposits of the second period of the Paleozoic Era, characterized by the appearance of primitive fishes.

53. It consists of Archaeozoic and Paleozoic strata in which Cambrian and Ordovician are dominated by limestone. The tectonism and weathering make it become a good reservoir.

54. Fracturing is a absolutely necessarily method for Daniudi upper Paleozoic sandstone gas reservoir to be put into production because of its compact reservoir.

55. There are great bifurcations as yet on the structural environment and on the evolution of the Xingmeng Paleozoic orogenic belt in Southeast Inner Mongolia during the Carboniferous Period.

56. Because of discovering successively clastic rock gas reservoirs in Permian of Upper Paleozoic in North E'erduosi Basin[sentencedict.com], the special attention has been paid to the material sources of these reservoirs.

57. The major structure in the area is the NE-NNE folded belt consisting of Banxi Group of the Middle Proterozoic era to the Ordovician system of the Early Paleozoic era.

58. The hydrocarbon generating potential of source rock is weaker in the hanging wall and the heavier relatively in the lower plat of upper Paleozoic in the west margin belt.

59. The Late Mesozoic characterized by higher temperature gradient is main period of gas generation and migration of Paleozoic coal series and carbonates.

60. The sandstone reservoir in the Upper Paleozoic Shan32 of Zizhou-Qingjian area is combinated first by quartz sandstone and next by lithic sandstone and lithoclastic quartz sandstone.
