Crustal remelting origin of highly silicic magmatism on the Moon
Orbital observations of non-mare, highly silicic volcanic constructs on the Moon challenge the conventional view of the formation of silicic crusts in the presence of water and plate tectonics—the former the Moon has in very short supply and the latter ...

Volumetric extrusive rates of silicic supereruptions from the Afro-Arabian large igneous province [PDF]
Quantifying the tempo of large-volume silicic magma generation and eruption is a long-standing but elusive task. Here we show that the three largest sequentially dated eruptions, totaling >4,300 km3, occurred within 48 ± 34 kyr and yield the highest ...

Large-scale crustal growth driven by LIP magmatism during the Paleoproterozoic [PDF]
The evolution of Earth’s continental crust is crucial for understanding geodynamics, climate regulation, and the origins of life. The Paleoproterozoic, marked by the Great Oxidation Event and the consolidation of plate tectonics, was a critical interval ...

Mesoscale and microscopic structures record compaction and crystal-melt segregation in silicic mushes [PDF]
Gravitationally-driven compaction has been proposed as an important mechanism for crystal-melt segregation in silicic mushes. However, there is no microstructural evidence of crystal deformation consistent with compaction in silicic plutonic rocks.

Direct evidence of the molecular basis for biological silicon transport [PDF]
Diatoms sheath themselves in a self-made casing of silica, which requires the function of silicic acid transporters. Here, the authors identify versions of these transporters that are experimentally tractable, and develop a fluorescence method to study ...

Evidence for the formation of silicic lava by pyroclast sintering [PDF]
Silicic lavas can be produced by the sintering of pyroclasts in the volcanic sub-surface, and then advected out of the vent. Here, we provide evidence for this mechanism preserved in the exposed post-glacial remnants of a silicic volcanic conduit at ...

Structure and function of a silicic acid channel Lsi1
Silicon is a beneficial element for plant growth and production, especially in rice. Plant roots take up silicon in the form of silicic acid. Silicic acid channels, which belong to the NIP subfamily of aquaporins, are responsible for silicic acid uptake.

Removal of Silicic Acid from Feed Water Using a Tiron Combined Anion Exchange Resin Column
Thorough removal of silicic acid from treated water, as a water pretreatment procedure, is essential for the prevention of silica deposits on anion exchange resins and reverse osmosis membranes.

Buried Silicic Volcanoes Discovered in the Gruithuisen Region on the Moon
Mons Gruithuisen is a rare example of nonmare silicic volcanoes on the Moon. We have conducted analyses of the topography, chemical compositions, and subsurface structures of the Gruithuisen region based on remote sensing and gravity data.
