0540686NatlandA Chapman Conference, "The Great Plume Debate", will be held in Fort William,Scotland in August, 2005. A global debate is now in progress concerning the existenceof mantle plumes, the number of deep mantle plumes, and the viability of alternativemodels. Recent meetings have focused either on plume theory or alternatives, and it isnow timely to hold a discussion meeting that brings together representatives of both sidesof the debate. The primary objectives will be to:a) Clarify and define both the plume and alternative theories, their predictions and howthey may be tested;b) Match them against one another; andc) Identify the most important avenues of future research that may ultimately lead toresolution of the debate.The meeting will be balanced and structured to present both pro-plume and alternativepoints of view in sessions dealing with theory, mantle physics and dynamics, fieldevidence, age dating, seismology, temperature, petrology and geochemistry, andplanetary aspects. The conveners include two who are arranging the pro-plume side ofthe discussion, and two who are arranging the plume-skeptic side. The venue in Scotlandwas chosen to facilitate international participation, and to allow participation in fieldtrips. These will be to several of the major central volcanic complexes and intrusivecenters of the Scottish Hebrides that have long provided many of the important conceptsof igneous structural geology and petrogenesis in what is now termed the North AtlanticLarge Igneous Province.Average expenses for this meeting for US participants, based on the currentdollars to sterling exchange rate will be about $2100, including $1000 for air fare.Presently, there are 52 U.S. applicants who have submitted abstracts including 5 students.Many of these have requested financial assistance. This award ($20,000) will defray costs for 25 participants, especially students and young scientists, by an average amount of $800.

查普曼会议将于2005年8月在苏格兰威廉堡举行，名为“羽流大辩论”。目前正在进行一场关于地幔热柱的存在、深部地幔热柱的数量以及替代模式的可行性的全球辩论。最近的会议要么集中在羽流理论上，要么集中在替代方案上，现在是时候举行一次讨论会议，让辩论双方的代表聚集在一起。会议的主要目标将是：a)澄清和定义羽流和替代理论，它们的预测和如何进行检验；b)将它们相互比较；c)确定未来研究的最重要途径，最终可能导致辩论的解决。会议将得到平衡和组织，以便在涉及理论、地幔物理和动力学、野外偏差、测年、地震学、温度、岩石学和地球化学以及行星方面的会议上提出支持热柱和替代观点。召集人包括两名安排支持羽毛球讨论的人和两名安排羽毛球怀疑者的人。选择在苏格兰的场地是为了促进国际参与，并允许参加实地考察。这些将是苏格兰赫布里底群岛的几个主要的中央火山综合体和侵入中心，长期以来，这些中心提供了许多重要的火成岩构造地质和岩石成因概念，现在被称为北大西洋大型火成岩省。根据目前的美元兑英镑汇率，美国与会者的平均费用约为2100美元，其中包括1000美元的机票费用。目前，有52名美国申请者提交了摘要，其中包括5名学生。其中许多人要求财政援助。这笔奖金(20,000美元)将支付25名参与者的费用，特别是学生和青年科学家，平均金额为800美元。
