0087361WrightThis is a project to study the Caribbean-South American oblique arc-continent collision zone using various geologic (mapping, structure), geochemical (Ar-Ar and U-Pb Geochronology), and seismic (active MCS with onshore/offshore recording using OBS instruments, passive array) techniques. There will also be a geodynamic modeling study that, very innovatively, includes the dynamics of crust-mantle interaction. The overall goal of the project is to understand further the geometry and chronology of a world class, arc-continent accretion event. Seosmic/geological cross-sections are to be derived for several transects across the orogen at different ages of collision. The group of investigators include highly capable seismologists in both active and passive seismology, as well as geologists familiar with the orogenic developments on land. The cooperation with Venezuelan scientists and students is excellent. ***

0087361赖特这是一个利用各种地质（绘图、结构）、地球化学（Ar-Ar和U-Pb年代学）和地震（主动MCS，利用OBS仪器、被动阵列进行陆上/海上记录）技术研究加勒比-南美洲斜弧-大陆碰撞带的项目。 还将进行一项地球动力学建模研究，其中非常创新地包括壳幔相互作用的动力学。 该项目的总体目标是进一步了解世界级弧-陆增生事件的几何学和年代学。 在不同的碰撞年龄，将对横跨造山带的几个断面得出地震/地质横截面。 这组调查人员包括在主动和被动地震学方面能力很强的地震学家，以及熟悉陆地上造山运动发展的地质学家。 与委内瑞拉科学家和学生的合作非常好。***
