Protracted intercontinental aridification preserved within the early Late Cretaceous strata of the Eastern Gobi Basin, Mongolia

Sedimentology, Volume 73, Issue 1, Page 147-185, January 2026.
ABSTRACT Mongolia's Eastern and Western Gobi Basins preserve a globally significant record of Cretaceous terrestrial vertebrates, yet their biostratigraphic correlations are complicated by a complex geological history. The Eastern Gobi Basin, a northeast‐southwest trending fault‐bounded rift system, includes several minor sub‐basins with distinct ...

Ichnological discrimination of hemipelagic‐dominated slope versus basin‐floor mudstones: Insights from early Viséan successions of a distally steepened ramp, northern Iran

The Depositional Record
Integrating sedimentological and ichnological data from the uppermost unit of the Mobarak Formation (early Viséan, Northern Iran), deposited in a distally steepened ramp, provides insights into deep‐water muddy gravity flows in mud‐rich slope settings ...

Application of digital image treatment to the characterization and differentiation of deep-sea ichnofacies

The ichnofacies model proposed by Seilacher in the 1960’s stands as one of the main tools used in the ichnological research. Based on the integration of numerous ichnological and sedimentological observations, it entails a precise characterization of the
