A preliminary study on genesis of the Qiongzhou Straits     

Zhang Hunan  Chen Weiguang 《海洋学报(英文版)》1989,8(1):113-123

The active period of the faults in the Qiongzhou Straits occurred principally in the Tertiary. The rupture zone is situated in the nearly E-W striking tectonic lowland between the Leizhou Peninsula and the Hainan Island, which was preformed by the southward and northward compressions due to the expansion of the South China Sea Basin. During the interglacial periods in the Quaternary, the lowland was inundated and deepened gradually due to erosion by sea curfent. It was until the last uprising of sea level during the postglacial period that the Qiongzhou Straits assumed its present appearance.  相似文献   

Testing the distance-duality relation with data from galaxy clusters and type Ia supernovae     

Xiang-Yun Fu  Pu-Xun Wu  Hong-Wei Yu  Zheng-Xiang Li Institute of Physics  Hunan University of Science  Technology  Xiangtan  China Center for Nonlinear Science 《中国天文和天体物理学报》2011,(8)

We test the distance-duality(DD) relation by combining the angular diameter distance DA provided by two galaxy cluster samples compiled by De Filippis et al.(the elliptical β model) and Bonamente et al.(the spherical β model),and the luminosity distance DL from Constitution and Union2 type Ia supernova(SNe Ia) datasets. To obtain DL associated with the observed DA at the same redshift,we smooth the noise of the SNe Ia in a model-independent way,obtain the evolutionary curve of DL and,finally,test the DD rel...  相似文献   

Recently Ratified and Proposed Cambrian Global Standard Stratotype-section and Points     

PENG Shanchi  ZHU Xuejian  ZUO Jinxun  LIN Huanling  CHEN Yong’an  WANG Longwu 《《地质学报》英文版》2011,85(2):296-308

This paper briefly summarizes an officially ratified Global Standard Stratotype-section and Point (GSSP) and a proposed GSSP for global stages of the Cambrian System. The Luoyixi section near Luoyixi town, Guzhang, northwestern Hunan is ratified as the boundary stratotype for the base of the global Guzhangian Stage, which is the upmost stage of an unnamed series termed provisionally as Cambrian Series 3. The GSSP position lies 121.3 m above the base of the Huaqiao Formation in the section, coinciding with the first appearance of the cosmopolitan agnostoid trilobite Lejopyge leavigata. The Duibian B section at Duibian village, Jiangshan, western Zhejiang, is proposed as the boundary stratotype for the base of the proposed global Jiangshanian Stage that is the second stage of the Furongian Series. The proposed GSSP position lies 108.12 m above the base of the Huayansi Formation in the section, coinciding with the first appearance of the cosmopolitan agnostoid trilobite Agnostotes orientalius. This horizon is also with the first appearance of the cosmopolitan polymerid trilobite Irvingella angustilimbata.  相似文献
