Lithofacies Palaeogeography of the Late Permian Wujiaping Age in the Middle and Upper Yangtze Region, China
Journal of Palaeogeography 2014, 3(4): 384-409 DOI: 10.3724/SP.J.1261.2014.00063 Lithofacies palaeogeography and sedimentology Lithofacies palaeogeography of the Late Permian Wujiaping Age in the Middle and Upper Yangtze Region, China Jin-Xiong Luo*, You-Bin He, Rui Wang School of Geosciences, Yangtze University, Wuhan 430100, China Abstract The lithofacies palaeogeography of the Late Permian Wujiaping Age in Middle and Upper Yangtze Region was studied based on petrography and the “single factor analysis and multifactor comprehensive mapping” method. The Upper Permian Wujiaping Stage in the Middle and Upper Yangtze Region is mainly composed of carbonate rocks and clastic rocks, with lesser amounts of siliceous rocks, pyroclastic rocks, volcanic rocks and coal. The rocks can be divided into three types, including clastic rock, clastic rock-limestone and lime- stone-siliceous rock, and four fundamental ecological types and four fossil assemblages are recognized in the Wujiaping Stage. Based on a petrological and palaeoecological study, six single factors were selected, namely, thickness (m), content (%) of marine rocks, content (%) of shallow water carbonate rocks, content (%) of biograins with limemud, content (%) of thin- bedded siliceous rocks and content (%) of deep water sedimentary rocks. Six single factors maps of the Wujiaping Stage and one lithofacies palaeogeography map of the Wujiaping Age were composed. Palaeogeographic units from west to east include an eroded area, an alluvial plain, a clastic rock platform, a carbonate rock platform where biocrowds developed, a slope and a basin. In addition, a clastic rock platform exists in the southeast of the study area. Hydro- carbon source rock and reservoir conditions were preliminarily analyzed based on lithofacies palaeogeography. -

In this paper, we report a new case of Bauxite deposit uranium enrichment in a paleo-karstic bauxite deposit at Yunfeng, southwestern China, present electron probe Uranium minerals micro-analyzer (EPMA) and Raman spectroscopic evidence for the presence of separate U-minerals, and propose EPMA a model in which uranium was enriched through successive processes from chemical weathering through early Raman spectroscopy to burial diagenesis. The Yunfeng bauxite ores, developed in Lower Carboniferous mudrocks overlying Middle to Yunfeng Guizhou Upper Cambrian carbonate rocks, contain 18.0 to 62.4 ppm (average 35.1 ppm) U, which is much high than the abundances in average crustal rocks (1–3 ppm). Micron-sized uraninite occurs as rims of Ti-oxides, fillings of micro-fractures in kaolinite, and disseminated grains in association with sulfides in the matrix of diaspore and kaolinite. -

Volume 90 Annals Number 4 of the 2003 Missouri Botanical Garden A REVISION OF THE Yelin Huang,2 Peter W. Fritsch,3 and 2 IMBRICATE GROUP OF Suhua Shi STYRAX SERIES CYRTA (STYRACACEAE) IN ASIA1 ABSTRACT Several taxonomic treatments of Styrax (Styracaceae) exist in regional ¯oras of Asia, but the Asian species of the genus have not been comprehensively revised since 1907. To help rectify this, we conducted a taxonomic revision of the Asian species of Styrax series Cyrta with imbricate corolla aestivation. Our revision comprises 17 species with a combined distribution from Japan south to Sumatra and west to Nepal. The circumscriptions of the heretofore poorly de®ned species S. hookeri and S. serrulatus are clari®ed. Styrax agrestis var. curvirostratus is elevated to the species level, and lectotypes are selected for S. duclouxii, S. ¯oribundus, S. hemsleyanus, S. hookeri, S. hookeri var. yunnanensis, S. hypoglaucus, S. japonicus, S. limprichtii, S. macranthus, S. obassia, S. perkinsiae, S. serrulatus var. latifolius, S. shiraianus, S. supaii, and S. wilsonii. Keys, descriptions, and distribution maps are provided for all species. Key words: eastern Asia, Styracaceae, Styrax, Styrax series Cyrta. Styrax L. comprises about 130 species of trees ern Argentina and Uruguay (Fritsch, 1999, 2001). and shrubs distributed in eastern and southeastern Styrax is by far the largest and most widespread of Asia, the New World, and the Mediterranean region the 11 genera in the Styracaceae sensu Fritsch et (Fritsch, 1999). The range of this genus is typical al. (2001) and Fritsch (in press a). Characters of many plant groups distributed among the refugia unique to Styrax in relation to the family include a of Tertiary mixed-mesophytic forests in the North- stamen tube attached high (vs. -

One Security, Two Prices: Evidence on Stock Market Bubbles from the Shanghai-Hong Kong Stock Connect Program Abstract In this paper, a unique data sample from cross-listed stocks in two segmented but partially con- nected markets allows us to examine the implications of the bubble theories while controlling for fundamentals. We study price, volume, volatility and liquidity changes surrounding the launch of the Stock Connect program on 17 November 2014, which links trading in A shares listed on the Shanghai Stock Exchange (SSE) to their ‘twin’ (cross-listed) H shares traded on the Hong Kong Stock Exchange (SEHK). The price and price discovery gaps of the A-H shares should be larger after the Stock Connect if the speculative trading in Shanghai market explains most of the price differences. On the other hand, there should be a price convergence effect after the Stock Connect if the efficient market theories explain a fraction of the price disparity since information asym- metry and limits of arbitrage are reduced. -

Spatial Correlation Between Type of Mountain Area and Land Use Degree in Guizhou Province, China
sustainability Article Spatial Correlation between Type of Mountain Area and Land Use Degree in Guizhou Province, China Yuluan Zhao 1,2 and Xiubin Li 2,* 1 School of Geographic and Environmental Sciences, Guizhou Normal University, Guiyang 550001, China; [email protected] 2 Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China * Correspondence: [email protected]; Tel.: +86-10-6488-9297 Academic Editors: Fausto Cavallaro and Marc A. Rosen Received: 17 May 2016; Accepted: 24 August 2016; Published: 29 August 2016 Abstract: A scientific definition of the type of mountain area and an exploration of the spatial correlation between different types of mountain areas and regional land use at the county level are important for reasonable land resource utilization and regional sustainable development. Here, a geographic information system was used to analyze digital elevation model data and to define the extent of mountainous land and types of mountain areas in Guizhou province. Exploratory spatial data analysis was used to study the spatial coupling relation between the type of mountain area and land use degree in Guizhou province at the county level. The results were as follows: (1) Guizhou province has a high proportion of mountainous land, with a ratio of mountainous land to non-mountainous land of 88:11. The county-level administrative units in Guizhou province were exclusively mountainous, consisting of eight semi mountainous counties, nine quasi mountainous counties, 35 apparently mountainous counties, 13 type I completely mountainous counties, and 23 type II completely mountainous counties; (2) The land use degree at the county level in Guizhou province have remarkable spatial differentiation characteristics.
