Silica is unlikely to be soluble in upper crustal carbonatite melts. [PDF]
Nat Commun, 2023 A consensus among all experimental studies is that the solubility of silica (SiO 2 ) is low in upper crustal carbonatite melts of below 5 kbar and 1000 °C (mostly much less than 5 wt% SiO 2 ) 1,2 , in agreement with most natural melt inclusion studies 3 –

Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Evolution of Carbonatite Magmas in the Upper Mantle and Crust
Elements, 2021 Carbonatites are the most silica-poor magmas known and are amongst Earth’s most enigmatic igneous rocks. They crystallise to rocks dominated by the carbonate minerals calcite and dolomite.
