该项目包括对太平洋-南极板块边界上两个最大的转换断裂带进行地球物理调查和地质采样的实地项目。主要目的是：(1)了解长快滑转换断层的构造和构造；(2)对主要基于遥感地震活动性和卫星测高的构造推断进行检验；(3)了解变换中暴露的地壳岩石的地质组成；(4)利用在快速扩张的山脊上通常难以疏浚的已知的下地壳和上地幔岩石露头。＊＊＊
英文摘要
9217707 Lonsdale This project includes a field program to geophysical survey and geologically sample the two largest transform fault zones on the Pacific-Antarctic plate boundary. The principal objectives are: (1) to understand the structures and tectonics of long, fast- slipping transform faults; (2) to test structural inferences based largely on remotely sensed seismicity and satellite altimetry; (3) to learn the geologic composition of the crustal rocks exposed in the transforms, and (4) to exploit known outcrops of lower crustal and upper mantle rocks that the usually inaccessible to dredging on fast-spreading ridges. ***
