The discovery of tridymite in Mars’s Gale Crater triggered debate about the rare mineral’s origins. A research team recently suggested a scenario with explosive implications.
Diatoms contribute to global oxygen production, marine food webs, and carbon sequestration, but scientists predict that diatom populations will decline due to ocean acidification associated with climate change.
Watersheds have unique patterns of silicon export due to differences in subsurface water routing and biogeochemical reactions.
Scientists engineer a way to layer materials to boost efficiency without interrupting manufacturing processes.
The first comprehensive analysis of what the sarsen stones are made of came about with new technology—and good old-fashioned luck.
Tiny, shelled protists known as Rhizaria may be responsible for up to one fifth of the total amount of silica produced by the world’s oceanic organisms.
Hydrous silica-rich magmas can degas through connected bubble pathways when as little as 20% crystals are present, influencing transitions from explosive, Vulcanian-style eruptions to lava effusion.
Phaeodarians play a major role in marine nutrient cycle.
Researchers probe millennia-old deep-ocean sponges for links between ocean nutrients and climate.
Cosmogenic silicon-based estimates of the amount of biogenic silica stored in clays along continental margins could explain the large discrepancy in the nutrient’s global marine budget.
