INTRODUCTIONIn recent years a num ber of detailed m ineralogical- petro-logical studies have been carried out on the UHP and HPmetamorphic belts in the Dabie- Sulu region,central China(see review papers by Jahn,1999;Ernst and L iou,1999;Wallis et al.,1999;Hacker et al.,1996 ;L iou et al.,1996 ;Cong et al.,1994) . Various tectonic evolution models for theUHP belt in the Dabie- Sulu region have been constructed(e.g.,Webb etal.,1999;Hacker et al.,1996 ;Cong et al.,1994) .However,as … 相似文献

Biomarkers have been widely used to exploreglobal change such as paleocli mate and paleovegeta-tion based on the analyses of marine sedi ments( Volkman et al ., 1995 ) , lacustrine sedi ments(Sheng et al ., 1999) , snow and ice ( Xie et al .,1999) ,peat (Xie et al .,2004) ,and stalagmites (Xieet al ., 2005 , 2003a) . Research into biomarkers inChina has been conducted in many soils . Aseries ofbiomarkers were identified from the Jiuzhoutaipaleosol-loess profilein Lanzhou,andn-alkanes werepr… 相似文献

Zircon SHRIMP Dating for the Weiya Pluton, Eastern Tianshan: Its Geological Implications 总被引:18,自引:4,他引:18
ZHANG Zunzhong GU Lianxing WU Changzhi LI Weiqiang XI Aihua WANG Shuo State Key Laboratory of Mineral Deposit Research 《《地质学报》英文版》2005,79(4):481-490
1 Introduction Voluminous literature has resulted from study of the geology and tectonic evironments of post-orogenic granitoids in eastern Tianshan (He et al., 1995; Han et al., 1997; Gu et al., 1999, 2001; Li et al., 2003; Chen et al., 2004). Previous contributions (Hu et al., 1997; Li et al., 2003) indicate that major events of continental collision in northern Xinjiang occurred around 300 Ma. Then, the tectonics converted from compression to extension, resulting in the uplifting of th… 相似文献

<正>碳酸盐熔体具有极低的粘度和独特的元素配分型式,是引起地幔交代作用和化学组成不均一性的重要介质之一(Yaxley et al.,1991;Rudnick et al.,1993;Coltorti et al.,1999)。火成碳酸岩是碳酸盐熔体结晶的产物,其镁(Mg)同位素组成可以为碳酸岩浆作用过程中镁同位素的分馏行为和地幔的镁同位素组成特征提供重要制约。为此,我们系统研 相似文献

The Hongliuguo-Lapeiquan mélange (Fig. 1) is seen in the Altyn fault belt (AFB), which is a large-scale sinistral strike-slip fault belt in the central Asia and also a part of the north natural boundary of the Qinghai-Tibetan plateau, separating the Tarim basin from the Qaidam basin (Zheng Jiandong, 1988; Avouac et al., 1993; Chalaron et al., 1995; Ge Xiaohong et al., 1998; Cui Junwen et al., 1996, 1997, 1999; Wang Yan et al., 1999). This mélange extends eastward from Hongliuguo thro… 相似文献

A Combined-Power Model for the Distribution of Axial Force in Shaft Anchor along Its Length 总被引:1,自引:0,他引:1
INTRODUCTIONThe anchorage of geomaterial , including shaftanchors and prestressed tendons ,is usually used ingeotechnical engineering. Owing to various advanta-ges ,these two anchorage types are widely used instructures in China ( Cao et al ., 2003 ; Fu et al .,1999 ;Lu et al .,1998 ; Li et al .,1995) . Shaft an-chors can be classifiedinto three kinds by the forceinthe shaft and cement grout :tensile ,press ,and sheartype (Lu et al .,1998) . The tensile type is the mostpopular in China… 相似文献

1. Introduction In recent years, growing attention has been focused on diapirs because of their significance to hydrocarbon accumulation in basins (Barber & Brown, 1988; Martin Hovland et al., 1989; Law et al., 1989; Collier et al., 1990; Lewis et al., 1994; Carmelo Monaco et al., 1996; Hieke et al., 1996; Hieke et al., 1996; Lewis et al., 1996; Limonov et al., 1996; Gallardo & Blackwell, 1999). With more and more effort devoted to the studies of the northern continental marginal basins … 相似文献
