研究的目的是调查弧后背景下的地壳增生类型和参数及其与洋中脊的差异。 这项研究对推测在弧后环境中产生的蛇绿岩有影响。 这项研究还将测试各种模型的构造历史的刘扩展中心区。 将用4公里160通道拖缆在9个采集日内对尤因河上的Lau盆地进行多通道地震反射勘测。
英文摘要
The objective of the study is to investigate crustal accretion styles and parameters in backarc setting and their differences from mid-ocean ridges. The study has implications for ophiolites that are presumed to be generated in backarc environments. The study will also test various models of tectonic history of the Lau spreading center area. A multichannel seismic reflection survey of the Lau Basin on the Ewing with a 4 km - 160 channel streamer over 9 acquisition days will be undertaken.
