Tte also suggest a possible comparison with the Ediacara trilobozoan fossils-Albumares and Anfesta from the shores of the White Sea in Russia. The re-cent discovery of a few skewed E. octobrachiata and walnut-shaped fossils with several carbonaceous meridian bands believed to represent lateral compressions of the same organism strongly suggests that this octoradial fossil is a ctenophoran.

First,we have discovered stone artefacts in caves, which have similar features to that were broadly scattered in laterite terraces in Bose basin(0.8 Ma B.P),next study on deposits and fauna will be hopefully contributed to document paleoenvironmental background of early human;Second,early human fossils,Gigantopithecus and mammalian fossils unearthed in Mohui cave provide new evidence of early human origin; Third,after our scientific excavation in Fengshudao site in Bose basin, we have found five pieces of bi-face LCT with 10 tektites and nearly 100 stone artefacts form original laterite deposit.This important discovery is very answerable to international question about stratigraphic suspect of LCT; Fourth, abounding mammallian fossils with human fossils and remains from early Pleistocene to Holocene have been uncovered after systematically excavation in marginal cave of Bose basin.These discoveries are significant to the study on human evolution and establishment of sequence of Quarternary biological-stratigraphic in southern China.

A highly diversified macrofossil assemblage was discovered from the Jiucheng Member of the uppermost Ediacaran of Jinning and Jiangchuan areas in eastern Yunnan. In addition to abundant Vendotaenia and Tyrasotaenia, large multicellular benthos such as Tawuia-like and Longfengshaniaceae fossils with diverse holdfast structures, have a distinct dominance, while there are still some other macrofossils with peculiar configurations as well as indistinct relatives. There is an obvious distinction between this assemblage and the macrofossil assemblages from the Doushantuo Formation and the Shibantan Member of the Dengying Formation in South China.

This dissertation was focused on the research about the formation and evolution of NQB from the Late Triassic to the early middle Epoch of Jurassic Period, including integrated analyzing the characteristic of the key stratigraphic surfaces, the time of the key stratigraphy, regional rock straigraphy, biostratigraphy and chronostratigraphy, sedimentary system and depositional facies. On basis of these analysis, a tectonic evolution model have been established for NQB during from the Late Triassic to the early middle Epoch of Jurassic Period.1. After the systematic surface analysis about main stratigraphy units, we found that:(1) the bottom of Xiaochaka formation was comformity with the middle Triassic in the basin, and in the north margin it was deposited and overlapped on the different period stratigraphy before Triassic.(2) The top surface of Xiaochaka formation developed regionally karst and paleo-karst breccia, and was uncomformity with Nadigangri Formation, these things suggest that NQB in Xiaochaka depositing stage was developed from middle Triassic basin, and then an extensive regression occurred, the deposition was over and erosion come into being.(3) The lithologic assemblage, geochemistry, mixed fossils, and stratigraphy overlapping characteristic of Quemocuo Formation in early middle Jurassic indicted that the uncomformity surface was an extension-unconformity.2. Integrated analysis about stratigraphy division and correlation indicted that:(1) the paleontologic assemblage of Xiaochaka formation show its time was Carian -Norian stage of late Triassic. According to it was overlapped by late Triassic Nadigangri Formation, so Xiaochaka formation should be Carian - early Norian stage.(2) the SHRIMP Zircon U-Pb age of Nadigangri formation volcanic rocks wear vary form 216 to 205 Ma, so its time should be Norian, but maybe extended into Rhaetian Stage.(3) The age of its bottom volcanic rocks, the fossil assemblages of its middle and upper members and overlapped by lower Jurassic, indicted the age of Riganpeicuo Formation was Norian - Rhaetian stage. And the same time, the volcanic rocks geochemistry of Nadigangri and Riganpeicuo formation both reflected that they wear formed in rift tectonic settings. The lower lithologic and surface characteristic, fossil assemblages and its upper maybe was conformity with lower Jurassic, all reflected that the age of Tumengela Formation in Tumen area should be Norian - Rhaetian stage.
论文对晚三叠世—中侏罗世早期盆地的形成与演化开展了研究,包括关键地层界面特征分析、关键地层时代归属分析、区域岩石地层、生物地层和年代地层的综合对比分析、区域沉积体系与沉积相分析、岩相古地理分析,最终建立晚三叠世—中侏罗世早期羌塘盆沉积—构造动力演化模式。1、系统的对各地层单元的界面分析发现:(1)肖茶卡组底界在盆地内部与中三叠统整合关系,在盆地北缘为沉积超覆于不同时代的前三叠系之上:(2)肖茶卡组顶界面发育古岩溶角砾岩,与上覆那底岗日组为岩溶不整合接触,说明肖茶卡组沉积时期的羌塘盆地是在早中三叠世的盆地基础发展起来的,后期出现了广泛的海退事件,使盆地结束沉积并遭受风化剥蚀作用;(3)中侏罗统雀莫错组的岩性组合特征、岩石化学特征、古生物化石混积和地层的沉积超覆现象均表现出裂陷环境下形成的伸展不整合面的特征。2、综合地层划分与对比分析认为:(1)肖茶卡组古生物化石组合反映其时代为晚三叠世卡尼期—若利期,根据其上被上三叠统那底岗日组不整合覆盖,将其时代厘定为卡尼期—若利期早期;(2)那底岗日组火山岩SHRIMP锆石U-Pb年龄在216~205 Ma之间,其时代主要为若利期,可能包含有瑞替期:(3)日干配错组底部火山岩的年龄、中上部化石组合及其被下侏罗统整合覆盖,综合反映的时代为晚三叠世若利期—瑞替期,而且那底岗日组火山岩和日干配错组火山岩的地球化学成分分析反映两者均为引张构造背景下的产物;土门地区的土门各拉组的下部岩性及界面特征、化石组合和上部可能被下侏罗统整合覆盖,综合反映其时代为若利期—若利期。
