New Bivalved Arthropods from the Cambrian(Series 3, Drumian Stage) of Western Hunan, South China

We report two new three-dimensionally phosphatized microfossils, Cambrolongispina reticulata gen. et sp. nov. and Cambrolongispina glabra gen. et sp. nov., from the middle Cambrian （Series 3, Drumian Stage） at Wangcun, Yongshun County, western Hunan, South China. They are bivalved arthropods, with thin, pliable, originally chitinous or chitin-calcareous shields （c. 350-517 I1 m long）. The shields are equipped with a pair of antero-dorsal spines. The spines are internally hollow, varying in length from 1/2 of to as long as the shield length in C. reticulata, and uniformly longer than the shield length in C. glabra. The spines of C. reticulata are ornamented with a longitudinal row of conical or blade-shaped denticles along the posterior edge. Cambrolongispina lacks marginal rims, valve lobation and sulci which are diagnostic of the Bradoriida sensu stricto. It also lacks a donblure/duplicature characteristic of phosphatocopids and some bradoriids. It could be related to the Monasteriidae （which may belong to Bradoriida sensu lato）, both characterized by a pair of antero-dorsal spines. Cambrolongispina may have been meiofaunai detritus feeders that lived on or within sediments. The antero-dorsal spines may have been sensory organs to detect nearby predators. The posterior denticles on these spines might have facilitated the sensory function of the spines.

Ore-Forming Material Sources of the Shizishan Pb-Zn Deposit in Western Hunan Province,China

Objective The Shizishan Pb-Zn deposit is located in the southeastern margin of the Yangtze Block,and its Pb-Zn orebodies are mainly hosted in the Lower Cambrian Qingxudong Formation limestone.Previous researches have investigated the geological characteristics,geochemistry and fluid inclusions of this deposit.

Tuntian System in Miao Region of Western Hunan in Independent Subprefecture Period

After the Miao insurgence in the Qianlong and Jiaqing periods,the government of Qing Dynasty directly raised four separate subprefectures to the independent subprefecture( Zhili Ting),and the state power penetrated into villages of Miao People. The success of this strategy lies in adjustment of Qing government to taxation mode in Miao Region of Western Hunan,which formed the taxation mechanism dependent on Tuntian system. This has both the background of the times and the foresight and sagacity of designers,and shows unique rationalist spirit of the Confucian culture.

Research on the Importance of Monetary Work to the Political Development of the Western Hunan and Hubei Base Areas

During the seven years revolution in the Western Hunan Hubei revolutionary base,currency experienced four stages of construction and development,and became the economic tool of revolutionary regime,and made considerable contribution;however,the importance of politics to financial work is obvious here.Due to the mistakes caused by the left leaning in the revolutionary work,the monetary work in the revolutionary base area in Western Hunan and Hubei has been seriously affected the final result of the influence is to withdraw from the circulation field with the transfer of the main body of the revolutionary team.

Structural deformation, metallogenic epoch and genetic mechanism of the Woxi Au-Sb-W deposit, Western Hunan Province, South China

The remobilization,migration,precipitation,and enrichment of ore-forming elements are closely related to structures.Therefore,detailed regional and ore-field structural analyses are critical for determining the genesis of a mineral deposit.The Jiangnan Orogenic Belt(JOB)is an important gold polymetallic metallogenic belt in South China,which is characterized by multiple periods of gold mineralization in the Paleozoic and Mesozoic.However,the genesis of these gold polymetallic deposits is still not well understood due to a lack of systematic research on the regional geology,ore-controlling structures and metallogenic mechanism.In this study,a detailed structural survey at the surface and in the subsurface tunnels was conducted on the Woxi Au-Sb-W deposit,the genesis of which is relatively controversial among the gold polymetallic deposits in the JOB due to poor structural constraints.In addition,a wolframite U-Pb dating was carried out to further constrain the relationship between structures and mineralization.Based on the results of these studies,together with those from previous studies,it is proposed that the Woxi deposit and surrounding areas likely underwent six periods of regional deformation,which are constrained in time and geodynamic setting.Furthermore,we present a systematic discussion on the roles of ore-controlling structures in the transportation,distribution,and deposition of ore-forming elements and localization of orebodies.According to the wolframite dating results,structural analyses,and previous data,we propose that the Woxi Au-Sb-W deposit was formed in two stages during the Yanshanian:a W(wolframite)-Au mineralization stage at ca.140 Ma and an Au-Sb-W(scheelite)mineralization stage at<130 Ma.These mineralizing events are interpreted to have a tight relationship with tectonic reactivation,and the ore-forming fluids were derived from deep sources,including those of magmatic or metamorphic origins.The Woxi deposit can therefore be classified as an“intracontinental reactivation-type”,and the mineralization is related to lithospheric extension caused by plate retreat,retention,and delamination following the cessation of westward subduction of the Paleo-Pacific Plate beneath the East Asian continent.

MICROFOSSILS FROM LATE PROTEROZOIC MANGANESE ORE DEPOSITS IN WESTERN HUNAN PROVINCE AND EASTERN GUIZHOU PROVINCE, SOUTH CHINA

Abundant microfossils and organic residuals have been discovered by SEM and normal palynological maceration from manganese ore beds intercalated in late Proterozoic glacial rock units in western Hunan Province and eastern Guizhou Province. Taking isotopic dating into consideration, the age of manganese ore deposits in both regions is suggested to be about 750 Ma. A distinct character is that a great quantity of colonial microfossil——Sphaerocongregus (or Bavlinella) and their degradational variants have been obtained from rhodochrosite. Their biological and biochemical functions, combined with the geochemical effect of manganese in different ways, may play an important role in the manganese cycle.

TECTONIC-GEOMORPHIC FEATURES OF THE STRIKE-SLIP FAULT ZONE IN EASTERN HUNAN AND WESTERN JIANGXI

Eastern Hunan-western Jiangxi, the main distribution domain of the Luoxiao MountainRange, is one of the key districts of the Circum-Pacific tectonically active belt in China, in whichNNE-trending en echelon strike-slip faulting since Cenozoic time has obviously controlled thefundamental framework of the modern land forms. Based on the study of tectonic evolution and ac-tive strike-slip faults, this paper discusses the forms, types and combinations of the modern tec-tonic land forms in this region.

清代湘西不二门观音岩寺福田碑刻与寺院供养的历史考察

清代湘西不二门观音岩寺的福田碑刻内容多讲述置办福田的事情,为了解清代湘西不二门观音岩寺的日常供养情况提供了重要文献依据。其福田经济规模小,经营机制简拙,生产方式处于较为原始的自然经济状态,整体财力呈寡弱状态。不二门观音岩寺的福田经济是适应湘西特定自然地理和历史及人文环境的结果,其“自立”“自养”的程度较高,有助于避免寺院经济受外界社会动荡而带来的脆弱性,这是湘西历史上佛教寺院能够保持良好社会适应力和较强社会参与力与影响力的根本原因。

农户视角下不同开发模式旅游乡村生态恢复力评价及影响因素研究——以湘西地区8个村为例
