Crystallochemical features of chlorites of the earth crust deep horizons

open access: yes, 2020
© SGEM2014. All Rights Reserved. This article analyzes finely dispersed matter in the deep horizons of the Earth's crust -the crystalline basement destruction zones of the East Russian Plate. In these areas, the complex of clay minerals is formed.

Salt Range Formation of Pakistan Preserves Unique Record of Volcanic Fertilization During the Ediacaran Shuram Excursion

open access: yesTerra Nova, EarlyView.
ABSTRACT Thin, discontinuous, organic‐rich oil shale beds in the siliciclastic‐evaporitic Salt Range Formation (SRF) of Pakistan are of approximate Neoproterozoic to Cambrian age based on stratigraphic constraints. The beds are enriched (26–43 wt.% total organic carbon, TOC) in aliphatic organic matter (OM) of low thermal maturity despite their ...

Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

Almond Shell‐Derived Cellulosic Microfibres: Extraction, Characterisation and Applications in Sustainable Paper‐Based Packaging

open access: yesPackaging Technology and Science, Volume 39, Issue 10, Page 1231-1251, October 2026.
Cellulosic microfibres were extracted from almond shells using organosolv, soda and kraft processes, and comprehensive physicochemical, surface, thermal and morphological characterisation demonstrated their strong potential as sustainable fillers for paper‐based packaging application. ABSTRACT This study develops pathways for the valorisation of almond

Porosity Preservation in Deeply Buried (8500 m) Jurassic Calcareous Mudstones of the Vienna Basin (Austria)

open access: yesTerra Nova, Volume 38, Issue 5, Page 306-313, October 2026.
ABSTRACT Significant porosity of more than 5% was found at depths of more than 8500 m in poorly sorted, calcareous mudstones of the Malmian Mikulov Formation. These overpressured rocks are the main hydrocarbon source rock in the Vienna Basin. Core samples from present‐day depths of 8150 m to 8550 m were analysed using X‐ray diffraction and scanning ...
