RIDGE Field School on the Structure and Genesis of the Troodos Ophiolite, Cyprus

将于1999年6月在塞浦路斯举办一个海脊野外学校，研究特罗多斯蛇绿岩的野外地质学，这是一个古老的海洋地壳岩石的典型地区，可以为了解现代海洋地壳的结构和成因提供重要的见解。该学院将侧重于蛇绿岩剖面的上部，在那里，海底火山岩和下面的侵入席状岩脉和上部深成岩剖面都暴露出来。本节还展示了古海底以下高温和低温热液蚀变过程的记录。 特罗多斯蛇绿岩是唯一一个几乎未变形、也未变质的大型蛇绿岩。因此，它提供了一个很好的洞察结构和建设的海洋地壳。对任何研究大洋中脊火山和热液过程的科学家来说，参观这一独特的地方都是一次宝贵的经历，使他们对活跃大洋中脊表面所见的次表面特征的性质有了新的认识。在为期6天的实地考察过程中，可以全面考察地质剖面，在露头上进行辩论，并通过一些有针对性的讲座进一步说明。 这种形式导致在扩展中心的地壳结构的理解大大提高，为各级科学家，但学校的重点将是研究生和早期职业科学家。 该实地学校将由一个由11名受邀研究人员组成的小组领导，这些研究人员具有特罗多斯蛇绿岩和/或大洋中脊过程地质学方面的专门知识。召集人将是利兹大学的Joe Cann、维多利亚大学的Kathy Gillis和塞浦路斯地质调查局的Costas Xenophontos。后勤工作将由俄勒冈州州立大学的RIDGE办公室负责。

A RIDGE Field School will be held in Cyprus during June, 1999 to study the field geology of the Troodos Ophiolite, a classic region of old ocean crustal rocks which can provide important insights into the structure and genesis of modern oceanic crust. The school will focus on the upper parts of ophiolite section, where seafloor volcanics and the underlying intrusive sheeted dikes and upper plutonic sections are exposed. This section also displays a record of hydrothermal alteration processes below the ancient seafloor, at both high and low temperatures. The Troodos Ophiolite is the only accessible major ophiolite to have survived not only almost undeformed, but also unmetamorphosed. As such, it provides an excellent insight into the structure and construction of the ocean crust. A visit to this unique locality is an invaluable experience for any scientist working on volcanic and hydrothermal processes at mid-ocean ridges, providing new insight into the nature of the sub-surface features that underpin those seen at the surface in active mid-ocean ridges. In the course of a 6-day field trip, the geological section can be comprehensively inspected, argued over in outcrop, and further illustrated by a few, well-targeted lectures. This format leads to a much improved understanding of crustal construction at spreading centers, for scientists at all levels, but the focus of the school will be for graduate students and early-career scientists. The field school will be lead by a group of eleven invited researchers with an expertise in the geology of the Troodos Ophiolite and/or mid-ocean ridge processes. The convenors will be Joe Cann, University of Leeds; Kathy Gillis, University of Victoria; and Costas Xenophontos, Cyprus Geological Survey Department. Logistics will be handled by the RIDGE office at Oregon State University.
