Stable silicon isotope composition of sponge spicules from the Schultz Massif...

The stable silicon isotopic composition of siliceous sponge skeletal elements, spicules, is a potential archive of past dissolved silicon (silicic acid, or DSi) concentrations...硅质海绵骨骼组分——骨针（spicules）的稳定硅同位素组成，是重建过去溶解硅（硅酸，即DSi）浓度的潜在地质档案。
