Laguna Fuente de Piedra: An example of a dolomite factory recording ~50,000 years of depositional and paleoclimatic evolution

open access: yesThe Depositional Record, EarlyView.
This study characterises carbonate mineral precipitation mechanisms and their paleoenvironmental implications in a semi‐arid, saline playa lake system. SEM image with EDS spectra shows microcrystalline, spherical shaped dolomite crystals from Laguna Fuente de Piedra composed of nanocrystals with bacterial voids and EPS.

Reconstruction of palaeoflow and depositional dynamics from the Merjasec unroofed cave, Laze Plain (central Slovenia)

open access: yesActa Geographica Slovenica
Sparsely preserved unroofed cave deposits are ancient remains of cave systems. The Merjasec unroofed cave is a perfect example of poorly preserved cave deposits where conventional sedimentological study revealed a greater potential for the reconstruction

The implications of K-Ar glauconite dating of the Diest Formation on the paleogeography of the Upper Miocene in Belgium [PDF]

open access: yes, 2014
The glauconite-rich Diest Formation in central and north Belgium contains sands in the Campine subsurface and the hilly Hageland area that can be distinguished from each other.

Organoclay interaction response to sedimentary environment and sources in Paleogene shales from the Nanpu Sag: Insights for organic matter accumulation mechanism

open access: yesThe Depositional Record, EarlyView.
The deep paleo‐lake, characterised by low energy and moderate salinity, facilitated the input of fine‐grained minerals and the development of aquatic organic matter. Under the combined influence of the sedimentary environment and material source, mineral‐bound organic matter was formed, which played a crucial role in the enrichment of organic matter ...

Dynamic fluvial systems and gravel progradation in the Himalayan foreland [PDF]

open access: yes, 2000
Although the large-scale stratigraphy of many terrestrial foreland basins is punctuated by major episodes of gravel progradation, the relationships of such facies to hinterland tectonism and climate change are often unclear. Structural reentrants provide
