9402360 Perfit The PIs collected samples by rock coring and Alvin dives (Adventure I & II Cruises) on the ridge crest and flanks from EPR 9N area. In this project, they will obtain U-Th dates and geochemical analyses of these samples, and combine them with their photo interpretation to check their 3-D model of the magmatic system beneath fast- spreading ridge. Their goal is to determine magma residence times and magma residence times and magma generation and fractionation processes.

小行星9402360 PI通过岩石取芯和Alvin潜水（Adventure I II Cruises）在EPR 9 N区域的山脊顶部和侧翼采集样本。在这个项目中，他们将获得这些样品的U-Th年龄和地球化学分析，并将其与照片判读相结合，以检查快速扩张脊下岩浆系统的三维模型。他们的目标是确定岩浆的停留时间和岩浆的生成和分馏过程。
