Zhu, Fan, Zhou, 地球储层之间的硅循环为了解地球的运作方式提供了重要的见解, Gang-Jian, Xu, Tong-Yu, implying the existence of an unidentified mantle reservoir with complementary higher 30Si values. We present silicon isotope data from Cenozoic lamproites and their hosted mantle pyroxenite xenoliths from the Himalaya-Tibet orogen. These mantle-derived rocks have higher 30Si values than the BSE,板坯熔炼可以产生高30Si熔体和互补的低30Si残留物,创刊于2014年, some mantle-derived magmas exhibit lower 30Si values than the BSE, which resulted from reaction between mantle peridotite and 30Si-rich silicate melts from subducted Indian continental crust. Our results demonstrate that slab melting can produce high-30Si melts and complementary low-30Si residues. These products are unevenly distributed in the mantle - with high-30Si melts stored as metasomatic veins in the lithospheric mantle while low-30Si residues are recycled into deep mantle. This study provides evidence that mantle metasomatism by high-30Si slab melts creates heavy silicon reservoirs in the lithospheric mantle above continental slabs or cool mantle wedges above oceanic slabs.
