A model for the concomitant early formation of dolomite and fibrous clays in coastal bay systems: Evidence from the Eocene (Paris Basin, France)

Sedimentology, Volume 72, Issue 6, Page 1860-1898, October 2025.
ABSTRACT Detailed analysis of Lutetian–Bartonian deposits in the Paris Basin (‘Marnes et Caillasses’ Formation) provides new evidence of concomitant magnesian fibrous clays (palygorskite and sepiolite) and early microcrystalline dolomite. Although relatively uncommon in sedimentary archives, palygorskite and sepiolite are found in a wide range of ...

The increase of surface area of a Brazilian palygorskite clay activated with sulfuric acid solutions using a factorial design [PDF]

Materials Research, 2013
Palygorskite is fibrous clay in which the structural tetrahedral and octahedral layers are organized in a way that structural channels are formed, leading to high surface area.

Multiple Episodes of Fluid Alteration in Jezero Crater Indicated by MIST Mineral Identifications in PIXL XRF Data From the First 1100 Sols of the Mars 2020 Mission

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract The Mineral Identification by Stoichiometry (MIST) algorithm can identify mineral species in geochemical data sets. MIST is applied to X‐ray fluorescence chemical analyses from the Planetary Instrument for X‐ray Lithochemistry (PIXL) on the Mars 2020 Perseverance rover to identify mineral phases in abraded rock targets at Jezero crater.
