Granulometric, mineralogical and morphological investigation of the sea-bottom sediments in the Grgur Channel has revealed fi ve sediment types, the most frequent of which are muds containing some amount of coarse fractions (sand and gravel). The coarsest fractions are predominantly composed of recent shell fragments. Unexpected well rounded carbonate gravel was found SE of Prvić Island in 83 m...

Recent studies suggest a marked expansion of glacial ice across much of Gondwana beginning in the earliest Permian. Because expansion of glacial ice results in a lowering of sea level, the imprint of ice expansion should be evident worldwide as significant exposure event, hiatuses, or other evidence for sea level drop at or near the Pennsylvanian–Permian boundary. This literature review investi...

We predict that portions of the New Jersey continental slope were unstable approximately 0.5 million years ago. This instability was caused by rapid sediment loading during a Pleistocene sea-level lowstand and by flow focusing in underlying, permeable Miocene strata. The simulated instability is consistent with soft-sediment deformation and small slumps in Pleistocene strata of the Hudson Apron...

A simple mass balance model provides insight into the hydrologic, isotopic, and chemical responses of Lake Titicaca to past climatic changes. Latest Pleistocene climate of the Altiplano is assumed to have been 20% wetter and 5°C colder than today, based on previous modeling. Our simulation of lacustrine change since 15,000 cal yr B.P. is forced by these modeled climate changes. The latest Pleis...

In the Bengal Basin, the land surface exposed during the last lowstand of sea-level around 20 ka, and now buried by Holocene sediment, is capped by an impermeable clay palaeosol that we term the Last Glacial Maximum Palaeosol (LGMP). The palaeosol strongly affects groundwater flow and controls the location of arsenic pollution in the shallow aquifers of our study site in southern West Bengal an...

The Cisco Group on the Eastern Shelf of the Midland Basin is composed of fluvial, deltaic, shelf, shelf-margin, and slope-tobasin carbonate and siliciclastic rocks. Sedimentologic and stratigraphic analyses of 181 meter-to-decimeter-scale depositional sequences exposed in the up-dip shelf indicated that the siliciclastic and carbonate parasequences in the transgressive systems tracts (TST) are ...

The Paleocene/Eocene boundary has been a significant subject globally for sometimes now. This work focuses on the application of sequence stratigraphy where diagnostic microfossils trends of abundances and qualitative parameters can be integrated with sedimentology in the recognition of stratigraphic surfaces. Such surfaces / boundaries are highstand systems tract (HST), transgressive systems t...

The performance of both the tectonic uplift and 4th-order glacial eustatic sea level fluctuations in controlling stratigraphic architecture Quaternary lowstand prograding wedges Salento continental shelf (Southern Adriatic sea, Italy) during a time interval spanning from Middle Pleistocene to Holocene has been pointed out through interpretation high-resolution seismic reflection profiles their ...
