Advanced Research Workshop on "The Role of Fluids in Sediment Accretion, Deformation, Diagenesis, and Metamorphis at Subduction Zones"

将于1988年10月在意大利的Il Ciocco举行一次关于流体在俯冲带沉积物增生、变形、成岩作用和变质作用中的作用的讲习班。讲习班的重点是：（1）海底流体流动的表现;（2）流体的来源和演变;（3）流动的几何形状和物理性质;（4）流体对沉积增生棱柱体中构造的影响。讲习班的一个主要目标是为这一主题的国际合作研究方案制定科学计划。研讨会的与会者将由组织委员会推荐的特邀专家参加。在增生沉积环境中的流体流动问题是当今地球科学家们深入研究的一个课题。这些环境发生在世界各地的许多地方，在各种环境中。增生棱柱体中的物质被纳入大陆岩石中，但对这一过程以及水在岩石变形和变质中的作用知之甚少。需要进行国际协调与合作，以发展各种工具、设施和想法，切实有效地研究这些问题。该讲习班将有助于这些规划和协调工作。

A workshop on the role of fluids in sediment accretion, deformation, diagenesis and metamorphism at subduction zones will be held in October 1988 at Il Ciocco, Italy. The workshop will focus on (1) sea floor manifestations of fluid flow; (2) sources and evolution of fluids; (3) geometry of flow and physical properties; and (4) the effects of fluids on tectonics in sedimentary accretionary prisms. A major objective of the workshop is to develop scientific plans for an international program of cooperative research on the subject. Participants to the workshop will be invited experts, recommended by the organizing committee. %%% The problem of fluid flow in accretionary sediment environments is a subject of intense study by earth scientists today. These environments occur at a number of places around the world, in a variety of settings. The material in accretionary prisms is incorporated into continental rocks and not much is known about this process, nor about the role of water in deformation and metamorphosis of them. International coordination and cooperation are needed to develop the tools, facilities and ideas to study these problem efficiently and effectively. This workshop will help these planning and coordination efforts.
