This study assessed the dispersivity of soils extracted from the northern region of Cartagena de Indias (Colombia) using the pinhole test, crumb test, and chemical?microstructural analyses. Dispersive soils are susceptible to erosive phenomena upon conta...

Vanadium (V) and uranium (U) are critical elements for the energy and technology industry. They are characterized by low abundance in the earth crust´s rocks, but can be concentrated and give rise to sedimentary mineral deposits as a result of redox proc...

A c. 31 m thick section straddling the fossil find of an Early Pliocene baleen whale (?Brunella?, hereafter), made in 2007 in the sedimentary fill of the Middle Ombrone Basin of Tuscany, is investigated for depositional age and environment combining pala...

A transparent clay manufactured using Carbopol® UltrezTM 10 (simplified as U10) was introduced, and its manufacturing processes were briefly described. Both relative transparency (RT) and modulation transfer function (MTF) methods were used to quantify t...

Although drillholes in modern and ancient ostracods are known, the record is relatively scarce when compared to other taxa, and mainly exist with reference to the marine environment. Moreover, less is known about perforated ostracods, and more generally,...

The macroscopic mechanical properties of natural sedimentary soft soils, which are usually linked to their microstructure, are different from those of remolded soils. The interaction between soil structure and mechanical behavior is a manifestation of st...
