长江口岸带冲淤及后备土地资源的沉降效应——以上海崇明东滩为例

长江口入海泥沙的淤积是上海后备土地资源的重要来源，分析岸带冲淤的演变．有助于对岸带经济圈特别是围垦促淤地区因经济工程活动引发的地面沉降问题的剖析。本文以上海崇明东滩为例，分析30年来的冲淤变化及未来趋势，并据此对新近沉积土的地面沉降效应作简要阐述。     

First Record of Fossil Mesocupes from China （Coleoptera： Archostemata： Cupedidae）

Three new fossil species of the genus Mesocupes of fossil cupedids,M.angustilabialis sp. nov.,M.latilabialis sp.nov.and M.collaris sp.nov.,are described from the Jiulongshan Formation of Inner Mongolia,China.These new species are the first three records of fossil Mesocupes in China as well as the oldest ones in the world now.This finding also extends the geographical distribution of this genus from Central to East Asia.In addition,based on the ratio of the length of the last to the penultimate abdominal ventrites of new beetles distinctly lower than that of the species from the Karabastau Formation,the age of Daohugou fossil-bearing beds might be older than that of Karatau assemblage and consequently of Middle Jurassic.     

宝山西部矿区砂页岩型铅-锌矿成矿地质特征及新区找矿预测

宝山西部矿区砂页岩型铅-锌矿是近年来探获的一种新类型铅-锌矿体,赋存在次级倒转背斜核部测水组砂页岩地层中,层间滑动带的虚脱空间是其容矿空间,断层规模决定其长度规模,矿体产状严格受构造控制。根据其成矿特征及成矿条件,利用类比法,预测新的找矿靶区。

Hypoglossum fujianensis sp. nov. (Delesseriaceae, Rhodophyta) from Fujian Coast, China

Hypoglossum fujianensis sp. nov. is an epiphytic alga in the intertidal zone. Plants are light red, 0.9–2 cm high. Margin of branches gives rise to uniseriate hair-like rhizoids, formed outward from the fusion of the second-and third-order cells. Blades are single layered (except the midrib) and uncorticated. Tetrasporangial sori are formed on the middle part of blades. The globular tetrasporangia are developed from lateral pericentral cells. Project 39391800 supported by the NSFC.

Five-Stage Model of the Palaeozoic Crustal Evolution in Xinjiang

The great majority of the Palaeozoic orogenjc belts of Central Asia are of the intercontinental type, whose evolution always follows a five-stage model, i.e. the basal continental crust-extensional transitional crust-oceanic crust-convergent transitional crust-new continental crust model. The stage for the extensional transitional crust is a pretty long, independent and inevitable phase. The dismembering mechanism of the basal continental crust becoming an extensional continental crust is delineated by the simple shear model put forward by Wernike (1981). The continental margins on the sides of a gently dipping detachment zone and moving along it are asymmetric: one side is of the nonmagmatic type and the other of the magmatic type with a typical bimodal volcanic formation. In the latter case, however, they were often confused with island arcs. This paper discusses the five-stage process of the crustal evolution of some typical orogenic belts in Xinjiang.
