采薇海山群主要包含两个相对独立的平顶山,规模较大的主体海山为采薇平顶山((Pallada Guyot)),规模较小的附属海山为采杞平顶山,两者相距10.2 km(图1)。该海山群位于西太平洋东马里亚纳海盆东北缘,与Vlinder、Loah、Ita Mai Tai(维嘉海山)等海山构成整体呈NW向链状分布麦哲伦海山区。整个海山区属大型断块状隆起,延长近1200 km,海山区的海山年龄在80 Ma~100 Ma The mining seamount seamount mainly consists of two relatively independent Pingdingshan, the larger seamount seamount is the Pallada Guyot, and the smaller ancillary seamount is the quarry Pingdingshan, which is 10.2 km apart (Figure 1) . The seamount is located in the northeastern margin of the Eastern Mariana basin of the western Pacific Ocean and forms an NW chain-like distribution of Magellan seamounts along the seamounts of Vlinder, Loah and Ita Mai Tai. The whole seamount area is a large fault block uplift, extending nearly 1200 km, seamount seamount seamount age at 80 Ma ~ 100 Ma
