Therefore, we considered three frequencies above 15 Hz and up to 25 Hz with four different values of silica sand sample mass ranging from 6 to 20 g. Note that increasing the mass …

 — Highlights We investigate the origin of a laminated organic-rich chert formed at the PC–C boundary. It consists of non-annual couplets composed of organic and siliceous sediment. The δ 30 Si isotopic values indicate a marine, non-biogenic silica source of the chert. Chert formed in 2-steps, first sub-sea salt dissolution triggered silica-gel …

The main destination of Silica sands and quartz sands exports from Oman are: United Arab Emirates ($8.21M), Hungary ($261k), Iran ($5.08k), Sweden ($4.72k), and Somalia ($681). Imports In 2022, Oman imported $6.92M in Silica sands and quartz sands, becoming the 34th largest importer of Silica sands and quartz sands in the world.

Geological reservoir δ30 Si values have increasingly been applied as paleoclimate and paleoproductivity proxies. Many of these applications rely on the assumption that the surface Earth Si isotope budget is in mass balance with bulk silicate Earth, such that trends in δ30 Si over time can be attributed to changes in flux to or from key silica reservoirs.
