The Guanziyao lead-zinc deposit is located in the east edge of the Sichuan-Yunnan-Guizhou Pb-Zn metallogenic province. The ore bodies occur in the Upper Devonian-Lower Carboniferous dolomitic limestone and dolostone as stratoid or steep-dipping vein. Based on the analysis of the ore-forming geological conditions, this paper systematically studied the Pb isotopic compositions of the ore veins and surrounding rocks, and discussed the metallogenetic epoch and the source of ore-forming materials. The Pb isotopic compositions of the ore minerals in the deposit vary in narrow ranges and show characteristics of common lead. Pb model ages of the ore veins vary from 150 Ma to 169 Ma. Pb model ages of the veins may represent the major lead-zinc ore metallogenic period which is Yanshanian epoch. The distribution of the ore bodies are controlled by the early NE trending Yanshanian faults. Isotopic features of the ores suggest a multiple source, all of the stratigraphic units in the area may have contributed to ore mineralization. This study shows that there exists multi-stage and multi-cycle lead-zinc mineralization in the Sichuan-Yunnan-Guizhou Pb-Zn metallogenic province. And lead-zinc mineralization of the Yanshanian period should be emphasized in further prospecting. © 2017, Science Press. All right reserved.

The sporo-pollen fossils of Dicheiropollis were found from Esima area in southern Qiangtang Basin, Tibet. According to the emergence of the sporo-pollen fossils and a large number of Classopollis combinational features, the age of the strata can be assigned to Late Jurassic to Early Cretaceous. This discovery has important significance in that it not only provides evidence for the existence of Early Cretaceous strata in southern Qiangtang Basin but also offers clues to further geological work.

The Cambrian strata are widely distributed in western Hubei area. Abundant Sunella (Bradoriida), Perspicaris (large bivalved arthropods), macroscopic algal, hyolithes and (?)Sinospongia (Suspicious sponges) have been found in the lower black carbonaceous shale of the Cambrian Niutitang Formation from Tianzhu area of Changyang County, Hubei Province. In addition, scattered pyrite is seen in black shale. Based on a detailed study of palaeoecology and the characteristics of fossils preservation, the authors have reached the conclusion that, during the early sedimentary stage of Niutitang Formation in Changyang County of western Hubei Province, macroorganism lived in an environment of shallow water which was suboxic at the bottom, oxic in the upper part characterized by good light transmission and relative calmness, and that the sea bottom surface was located nearby the redox interface. Besides, under the background of rapid deposition, large amounts of water and dead biological-bodies were embedded in shale, the amount of water exchange between the depositional water and the external water decreased gradually, and H 2S gas was generated by rotton organism in the process of deposition, forming a strong reduction environment in sediments, so that organic matter could be preserved, which eventually formed black shale.

Zircon dating age of tuff bedding from the Sibao Group in Guangxi and Guizhou provinces is firstly reported in this paper. Integrating the zircon SHRIMP U-Pb dating of the granite which intruded into the Sibao Group, the group is thus determined to be Neoproterozoic. The Sibao Group (same as the Fanjingshan, Lengjiaxi and Shuangqiaoshan groups) and the Danzhou Group (same as the Xiajiang, Banxi and Heshangzhen groups), which are slighdy metamorphosed rocks are well developed in the Jiangnan Orogen, formed a metamorphosed basement of the Jiangnan old land. Many years ago, the Sibao Group was categorized into Mesoproterozoic, and it was main part of the Sibao Movement. The age of Sibao Group is still influencing the strata subdivision and correlation for the metamorphosed rocks in whole Jiangnan old land and has restricted the Chinese geologists to resolve the geological background and mineralization condition of the Jiangnan Orogen. In zircon study from bentonite in the Sibao Group, we've accurately determined the zircon dating of 841.7 Ma ± 5.9 Ma in the group and intruded granite zircon dating of 826.8 Ma ± 5.9 Ma from the Mt. Motianling.

Tethys Ocean formation and evolvement poses one of the important foundamental geological issues in studies concerning the Tibetan Plateau Integrating the field work, data analysis, previous studies, and particularly with the 1:250000 regional geology data, in Bayankala tectonic belt during Permian Trias, including the normal stratum, lithofacies character and tectonic paleogeography, we discussed the tectonic evolvement in order to improve the research level of the Tethys ocean development in Tibetan Plateau and Rodinia continent formation. The Permian Neogenes stratum appears in the main body of Bayankala tectonic belt, characterized by disappearing portion of Trias stratum before Permian. Permian Trias stratum was continuously aggraded in ocean environment. Bayankala Group is distributed widely and formatting thick in Trias in continent and ocean environment being flysch and little volcanic sediment. Jurassic Quaternary aggraded in continent formatting river and lake environment. Huangyangling Group aggraded in shallow and deep ocean environment formatting carbonate and fragmentary rock. It evolved from ocean environment to continent environment during Permian Trias after collision, orogenesis and the blue water vanish, as the north part of main double ocean region contrasting with the south Longmu lake Shuanghu ocean of Palaeo Tethys ocean lying between Talimu China Korea plate and south big continent (Gangwana continent).

In the Guizhou-Guangxi border area, several dacite layers were identified, which occur in interlayered form within the basalt of Sanmenjie Formation in upper Neoproterozoic Danzhou Group. The basalt and dacite compose a bi-model volcanic sequence. Both the basalt and the dacite are geo-chemically calcic and peraluminous, and display REE patterns with strong differentiation between LREE and HREE. Their primitive mantle normalized spider diagram is similar to that of enriched middle oceanic ridge basalt (E-MORB), suggesting that they might have been formed in a continental rift. The identification of bi-model volcanism, along with previously published in-site zircon U-Pb results, provides positive constraints for the stratigraphic correlation of Guizhou and Guangxi and for the tectonic reconstruction of the southwestern segment of the huge Jiangnan orogenic belt.

Micangshan Mountains and Longmenshan Mountains, as the boundary of Yangtze plate, are located in the north and west of Sichuan Basin in China. Their genetic relations are of extremely importance to the study of the hydrocarbon preservation conditions. The superimposed folds are very important pathways to study compounding and combining superposition of the structures. The junction area of Longmenshan Mountains and Micangshan Mountains is the polyphase compounding superposition of the structures and there are a great quantity of superimposed folds. By researching the superposed folds characteristics and restoring the palaeostress field, 3 group structure traces and at least 4 tectonisms are found in the junction area of Longmenshan Mountains and Micangshan Mountains. The Micangshan Mountains deformation has inheritance. In the Late Triassic, the earlier Micangshan Mountains uplift formed by the first phase S-N compressive stress field. In the Late Cretaceous -Paleocene, Micangshan Mountains were rapidly uplifted by S-N compressive stress field. Longmenshan Mountains intracontinental composite orogenic belt began later than Micangshan Mountains, but its major structure deformation was earlier than Micangshan Mountains large-scale uplifted. The deformations in Longmenshan Mountains, Micangshan Mountains, and Dabashan Mountains are polyphase, and their extensions are all successively forward basin, so they alternatively process.

Some zircon dating data of the tuffaceous bed are reported for the first time from the Sibao and Xiajia groups in Guanxi and Guizhou. In combination with the SHRIMP U-Pb dating of the granite that intruded into the Sibao Group, the Xiajia Group is determined to be of Late Neoproterozoic. These isotopic data are very important for us to redefine the age of the Sibao Group and to conduct regional correlation of strata in the corresponding period and tectonic evolution. The Sibao Group (the same as the Fanjingshan, Lengjiaxi and Shuangqiaoshan groups) and the Danzhou Group (the same as the Xiajiang, Banxi and Heshangzheng groups), which are subsequent metamorphosed rocks well developed in the Jiangnan Orogen, formed a metamorphosed basement of the Jiangnan Continent. In the past, the Sibao Group, which constituted the main part of the Sibao Movement, was designed to Mesoproterozoic, and the determined age still affects the stratigraphic subdivision and correlation of the metamorphosed rocks in whole Jiangnan Continent and restricts the determination of the geological background and metallogenic conditions of the Jiangnan Orogen. Based on studying zircon from bentonite in the Sibao Group and overlying strata, the authors accurately dated the zircon at (814.0±6.3) Ma in the Jialu Formation, and (773.6±7.9) Ma in the Qingshuijiang Formation. The series of zircon dating data have solved the problem of the Neoproterozoic ages and also provided a new marker for the Jiangnan Orogen.

Zircon dating (840Ma±5Ma) of tuff bedding is reported for the first time for the sixth member of the Huixiangping Formation in the Fanjingshan Group. The SHRIMP U-Pb dating of detrital zircon of the Furongba Formation is combined with tuff zircon dating (813.5Ma±9.6Ma) of the Xinzhai Formation in Xiajia Groups in Guizhou and Hunan Provinces, and also with the dating of the Sibao and Danzhou Groups in Guangxi. The tuff zircon age of the Huixiangping Formation in Fanjingshan Group is the same as the age of the Yuxi Formation of the Sibao Group, which intruded into early basic dykes and lava pillow in both groups, and developed late granite. It is very important to conduct the accurate dating of the events for the tectonic evolution in the southwest part of the Jiangnan orogenic belt. According to zircon U-Pb dating of lower metamorphosed rocks in the Jiangnan orogenic belt, there exist certain time differences for sedimentation between Fangjingshan Group, Sibao Group, Lengjiaxi Group, Shuangqiaoshan Group, Cangxi Rock Group, Yifeng Rock Group, Zhangcun Group and Shuangxiwu Group. Even the overlying strata have different ages, such as the Jialu Formation (814Ma) of the Xiajiang Group in Guizhou, the Hetong Formation (802Ma) of the Danzhou Group in Guahgxi, the Zhagnjiawan Formation (802Ma) of the Benxi Group in Hunan, the Dengjia Formation (766Ma) of the Dengshan Group in Jiangxi, and the Luojiamen Formation (791Ma) of the Heshangzheng Group in Zhejiang; there exists an angler unconformity between them, suggesting the existence of obvious orogenic event between the two tectonic horizons. The authors thus consider that the obtaining of more qualified chronostratigraphic U-Pb data will considerably influence the stratigraphic subdivision and correlation of the metamorphosed rocks in whole Jiangnan continent and restrict the geological background and metallogenic conditions of the Jiangnan orogen.
