Magadiite

Index Magadiite

Magadiite is a hydrous sodium silicate mineral (NaSi7O13(OH)3·4(H2O)) which precipitates from alkali brines as an evaporite phase. [1]

Alkali

In chemistry, an alkali (from Arabic: al-qaly “ashes of the saltwort”) is a basic, ionic salt of an alkali metal or alkaline earth metal chemical element.

Diagenesis

Diagenesis is the change of sediments or existing sedimentary rocks into a different sedimentary rock during and after rock formation (lithification), at temperatures and pressures less than that required for the formation of metamorphic rocks.

Hans P. Eugster

Hans Peter Eugster (19 November 1925, Igis, Switzerland – 17 December 1987, Baltimore) was a Swiss-American geochemist, mineralogist, and petrologist.

Intrusive rock

Intrusive rock (also called plutonic rock) is formed when magma crystallizes and solidifies underground to form intrusions, for example plutons, batholiths, dikes, sills, laccoliths, and volcanic necks.

Syenite

Syenite is a coarse-grained intrusive igneous rock with a general composition similar to that of granite, but deficient in quartz, which, if present at all, occurs in relatively small concentrations (.
