小行星9217707 该项目包括一个实地方案，对太平洋-南极板块边界上两个最大的转换断层带进行地球物理调查和地质取样。主要目标是：（1）了解长而快速滑动的转换断层的结构和构造;（2）检验主要基于遥感地震活动和卫星测高的构造推断;（3）了解变换中出露的地壳岩石的地质成分，（4）利用已知的下地壳和上地幔岩石露头，这些岩石通常无法在快速扩张的海脊上挖掘。 ***
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. ***
