Synthesis and characterisation of boron and gallium substituted saponite clays below 100 degrees Celsius and 1 atmosphere [PDF]

open access: yes, 2005
This paper describes a simple procedure for the synthesis of saponites with isomorphous substitution of Si4+ by B3+ and Ga3+ below 100°C and at 1 atmosphere. The XRD patterns of the Ga- and B-substituted saponites are similar to Al-substituted saponites.

Authigenic clay mineral evidence for restricted, evaporitic conditions during the emergence of the Ediacaran Doushantuo Biota

open access: yesCommunications Earth & Environment, 2022
The Ediacaran-age Doushantuo Formation, which hosts some of the oldest animal fossils, was likely deposited in a restricted, mildly evaporitic lagoon environment, according to petrographic analyses of saponite clays that suggest an authigenic origin.
