Therefore, the Prydz Belt is the key to understand the global tectonic evolution during the Neoproterozoic to early Paleozoic.

因此，开展普里兹造山带的研究对于揭示新元古代－早古生代的全球构造演化具有重要的科学意义。

This provides an evidence for discrimination and epoch of syn-orogenic granitoid, and also serves as a new chronological restriction for the subduction-orogeny of Altay orogen in Eopaleozoic (Ordovician-Devonian).

这为阿尔泰造山带的同造山花岗岩的鉴别和时代确定提供一个证据，也为阿尔泰造山带在早古生代的俯冲造山提供了一个新的年代学制约。

Based on the formation and separation of pan continent,the origin time of ancient species of Paeoniaceae might be back to the carboniferous of Paleozoic,and was not later than early Mesozoic.The modern species of the family flourished in Jurassic and early Cretaceous.

起源时间可以追溯到古生代的石炭纪，由于泛大陆形成与分离而形成芍药科的芍药组与北美芍药组遥相对应呈间断分布格局。

Graphite resources: minerals buried in the pre-Paleozoic strata of the Jining Group, is a metamorphic sedimentary type, the province's most important matter, in urban areas in the north of Fort Chee-hong, two to six acres.

石墨资源：该矿产埋藏于前古生代的集宁群地层中，属沉积变质型，全省唯此，分布在市区北部的宏赐堡、六亩地两处。

Paleozoic stratum can be separated east and west stratigraphical areas, according to lithological character and palaeontological information, contacted relationships and diversification of stratigraphical units in horizontal and vertical etc. The stratums in west area can be divided Devonian-Carboniferous Nanduan formation and Permian Laba formation, which is passive continental margin-bathyal depositional sequences comprised argillaceous and detrital rocks, small siliceous and carbonatite in upper. The stratums in east area can be divided lower-middle Devonian Wenquan formation and middle-upper Devonian Manxin formation, upper Devonian-lower Carboniferous Pingzhang formation, Carboniferous-Permian Yutangzhai formation, middle Permian Damingshan formation, upper Permian Shifodong formation respectively, moreover, middle-upper Permian Huoju formation is exposed in Menglian area.

根据地层的岩石组合、古生物、接触关系和地层单位的纵横向变化等特征，晚古生代的地层明显的可分为东、西两个地层小区：东部地层小区从下至上可划为泥盆—石炭系南段组、二叠系拉巴组，为一套泥质岩、碎屑岩，上部夹硅质岩、碳酸盐岩建造，属被动大陆边缘斜坡—半深海沉积；西部地层小区由下至上划分为下—中泥盆统温泉组、中—上泥盆统曼信组、上泥盆—下石炭统平掌组、石炭—二叠系鱼塘寨组、中二叠统大名山组、上二叠统石佛洞组，此外，在孟连一带尚出露中—上二叠统火居组。
