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“蛇绿岩和洋壳：来自实地研究和海洋钻探计划的新见解”，用于补充资金，以支付会议规划和执行期间一个月的工资，用于公布结果的资金，以及相关的会议费用，包括实地考察和补贴会议与会者的旅费。这次会议旨在让海洋和陆地科学家齐聚一堂，讨论涉及洋壳性质和起源的多学科研究。重点将把大洋钻探方案最近在各种海洋环境中的钻探结果与最近对蛇绿岩陆地类似物的研究结合起来，特别强调阿曼和特罗多斯蛇绿岩的结果。将讨论的具体ODP值包括在大洋中脊附近的上洋壳(哥斯达黎加裂谷)钻探所产生的结果，中到下洋壳和地幔的构造暴露(大西洋中脊、赫斯深和西南印度洋脊)，以及与大洋火山弧有关的构造环境(刘盆地、汤加前弧和伊苏-博宁-马里亚纳弧前和弧后)。本次彭罗斯会议将加强大洋岩石圈方案规划组的《大洋岩石圈方案规划小组》的目标和活动。会议将包括为期三天的会议，70名与会者参加，随后进行实地考察和一天的非正式讨论，将于1998年9月13日至1998年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. ***
