Microfacies analysis of the Late Maastrichtian- Danian Phosphatic Succession in the H3-Trebeel district, Western Desert of Iraq

, 2021
The Late Maastrichtian–Danian phosphatic succession prevails as a deposit to the west of Rutbah region, Western Iraq. This is manifested through the lithostratigraphic sections of boreholes (K.H5\6 and K.H 5\8) drilled previously in the area.

Varved sediment responses to early Holocene climate and environmental changes in Lake Meerfelder Maar (Germany) obtained from multivariate analyses of micro X-ray fluorescence core scanning data [PDF]

, 2017
We present an early Holocene record from Lake Meerfelder Maar in Germany for in-depth interpretation of depositional changes in annually laminated lake sediments as proxies for climatic and local environmental changes.

Assessing the intensity of Late Quaternary humid phases in the Nefud Desert, northern Arabia

Journal of Quaternary Science, Volume 41, Issue 2, Page 207-218, February 2026.
ABSTRACT The climate history of the major dryland zones of the world, such as the Saharo–Arabian Desert belt, plays a key role in the dispersal of early humans through these intermittently inhospitable regions. Here, we assess the relative intensity of Late Quaternary humid phases in northern Arabia through lithological, geochemical, palaeoecological ...

Geoarchaeological Investigation of Early Neolithic Lagoonal Fringe Landscapes in the Netherlands

Geoarchaeology, Volume 41, Issue 1, January/February 2026.
ABSTRACT Coastal wetlands have historically been portrayed as too marginal for early crop cultivation during the Mesolithic–Neolithic transition due to their dynamic hydrology, low elevation, and poor drainage. However, growing evidence suggests that these environments played a crucial role in the spread of agriculture. We examined buried and submerged

A novel population of composite mounds: their initiation, growth and demise. San Emiliano Formation, Cantabrian Mountains, Spain [PDF]

, 2018
Purpose: Mounds from the Pennsylvanian aged San Emiliano Formation (Cantabrian Mountains, Spain) are commonly well exposed. These mounds range from 2 to 50 m in height and are observed to be primary geological features.

Controls of Base‐Level Cycles on the Sedimentary Architecture of Subaqueous Distributary Channels in a Lacustrine Delta: A Case Study From the Chang 8 Member, Ordos Basin

Geofluids, Volume 2026, Issue 1, 2026.
Base‐level cycles serve as a crucial reference for the stratigraphic sedimentology. In lacustrine basins, high‐frequency base‐level changes contribute to significant diversity and complexity in sequences and sedimentary infilling. The sequences′ infill and facies distribution in lacustrine basins differ greatly from marine deposits.
