“白垩纪大洋红层——海洋/气候响应”研究进展综述

“白垩纪大洋红层”是中国学者提出并开拓的白垩纪研究新方向。在其所领导的两个国际地质对比计划项目(IGCP463/494)的推动下,“白垩纪大洋红层”所蕴含的古海洋与古气候意义,正引起越来越多的学者的重视。特别是近几年召开的学术会议对“白垩纪大洋红层”研究起到了很好的推动作用: (1)在2002 年度IGCP463 项目启动会议上,对“白垩纪大洋红层”的研究现状进行了初步的交流,制订了项目研究的总体目标和未来五年工作计划,并考察了亚平宁—阿尔卑斯—喀尔巴阡沿线的大洋红层;(2)2003 年度的IGCP463 工作会议和IGCP494 启动会议,不仅积累了大洋红层研究的资料,而且将白垩纪大洋红层研究推进到白垩纪中期;(3)2004 年度两个项目的工作会议,以及通过在第32 届国际地质大会特别讨论会的工作,进一步推进了大洋红层的研究,并将“白垩纪大洋红层”研究介绍给广大的国际地球科学界;(4)在欧洲地球科学联盟2005 年会上,“白垩纪大洋红层”研究体现出了多学科共同参与的可喜现象。回首近几年来的研究历程可以发现,“白垩纪大洋红层”研究已实现了如下转变:(1)从区域性研究到全球对比综合研究的变化;(2)从由中国科学家单独研究变为多个国家的科学家申请到项目和经费共同研究;(3)从举办IGCP项目学术年会快速向国际大会或

Progress in the studies of "Cretaceous oceanic red beds-Response to ocean/climate change" project

Cretaceous oceanic red beds”(CORB) being a new direction of international Cretaceous Research was put forward and initiated by Chinese scholars. Promoted by the two International Geological Correlation Program projects(IGCP 463/494),the paleo-oceanographic and paleo-climatological significance of CORB has been increasingly recognized by the international earth science community. Annual workshops of IGCP projects and other sessions played important roles in stimulating the CORB studies.(1) During the inaugural meeting of IGCP 463, 2002, colleagues were informed on the latest advances of CORB studies through a comprehensive exchange of data, ideas, etc. Research objectives and plans for the next five years were outlined for the investigation and study of the CORB along the Apennines-Alps-Carpathianse.(2) More data on CORB had been accumulated and problems on “mid-Cretaceous CORB” were put forward in the 2003 annual workshop of IGCP463 and inaugural meeting of IGCP494.(3) More progress in CORB studies had been made in the annual workshop of 2004 and “Cretaceous oceanic red beds” had been introduced to the international earth science communities during the CORB session in the 32nd International Geological Congress.(4) It was encouraging that during the CORB session of EGU (European Geological Union) 2005 Annual Symposium, multiple-discipline trends were embodied in the CORB studies. Such changes could be found by exploring the following experiences of CORB studies:(1) regional level of CORB studies can be a part of the global correlation program;(2) scientists from more countries have funds to study the CORB and not only from China;(3) CORB has often been the subject of international congresses and international annual symposia. This was not limited only to the annual workshop of the two IGCP projects;(4) the coordination of multidisciplinary researchers of the projects is now common. These are the challenges facing Chinese scholars. More endeavors are needed to keep our advantage in original CORB studies; and, more importantly, an able Chinese group in Cretaceous research could be fostered through the process of international cooperation.
