Penrose Conference on "Ophiolites and Oceanic Crust: New Insights from Field Studies and Ocean Drilling Program

OCE 98-13451 Dilek提案是为了支持彭罗斯会议“蛇绿岩和海洋地壳：来自实地研究和海洋钻探计划的新见解”，用于支付会议规划和执行期间一个月的工资，用于发布结果的资金，以及相关的会议费用，包括实地考察和会议参加者的差旅费补贴。这次会议的目的是把海洋和陆地科学家聚集在一起，讨论涉及海洋地壳性质和起源的多学科研究。重点将放在整合最近的海洋钻探项目钻探结果，从各种海洋环境与最近的蛇绿岩陆地类似物的研究，特别强调阿曼和Troodos蛇绿岩的结果。要讨论的具体ODP结果包括在海洋中脊（哥斯达黎加裂谷）附近的上部海洋地壳钻探所产生的结果，中下部海洋地壳和地幔的构造暴露（大西洋中脊、赫斯深和西南印度洋脊），以及与海洋火山弧相关的构造环境（劳盆地、汤加前弧和伊豆-波宁-马里亚纳前弧和后弧）。这次彭罗斯会议将扩大ODP海洋岩石圈项目规划小组的目标和活动。会议将包括为期三天的70名与会者会议，随后是实地考察和一天的非正式讨论，会议将于1998年9月13日至9月17日举行。＊＊＊

OCE 98-13451 Dilek Proposal is for support of a Penrose Conference on "Ophiolites and Oceanic Crust: New Insights from Field Studies and Ocean Drilling Program" for supplemental funds to cover one month of salary during conference planning and execution, for funds to publish results, and for associated conference costs that include a fieldtrip and subsidization of travel costs for conference attendees. The conference is designed to bring together both marine and land scientists for discussion of multidisciplinary studies involving the nature and origin of the oceanic crust. Emphasis will be placed on integrating recent Ocean Drilling Program drilling results from a variety of oceanic environments with recent studies of ophiolitic land analogues, with special emphasis on results from the Oman and Troodos ophiolites. Specific ODP results to be discussed include those resulting from drilling in upper oceanic crust near a mid-ocean ridge (Costa Rica Rift), tectonic exposures of middle to lower oceanic crust and mantle (Mid-Atlantic Ridge, Hess Deep, and Southwest Indian Ridge), and tectonic environments associated with oceanic volcanic arcs (Lau Basin, Tonga forearc, and Izu-Bonin-Mariana forearc and backarc). This Penrose Conference will augment the objectives and activities of the ODP Architecture of the Oceanic Lithosphere Program Planning Group. It will consist of a three day meeting for 70 participants, followed by a fieldtrip and a day of informal discussions, to be held 9/13/98-9/17/98. ***
