US-Japan Marine Geophysical Study of the Solomon Island Arc-Ontong Java Plateau Convergent Zone, Southwest Pacific Ocean

9301608曼：所罗门群岛是地球上唯一有可能研究世界上最大、最厚的海洋高原之一的中新世-上新世浅层俯冲作用的构造影响的地方。这是一个美日合作项目，绘制所罗门群岛辐合带的地壳和上地幔结构。多通道地震研究的主要目的是测试马莱塔背斜构造的两种模型——白垩纪-新生代中上层灰岩、玄武岩和碎屑岩的变形楔块，大多数先前的工作者都认为它是Ontong爪哇高原的一个新兴部分。＊＊＊

9301608 Mann The Solomon Islands is the only place on Earth where it is possible to examine the tectonic effects of Mio-Pliocene shallow subduction of one of the world's largest and thickest oceanic plateaus. This is a US-Japan cooperative program to map crustal and perhaps upper mantle structures in the Solomon Islands convergent zone. The primary objective of the multi-channel seismic study is to test two models for the formation of the Malaita anticlinorium-the deformed wedge of Cretaceous-Cenozoic pelagic limestone, basalt, and clastic rocks that most previous workers agree to be an emergent part of the Ontong Java Plateau. ***
