The Levantine high productivity sequence is a product of an extensive upwelling system that operated in the Late Cretaceous along the SE Tethyan margin. This system resulted in the deposition of a unique sequence of carbonate, chert, porcellanite, ph

As nanoscale materials have gained in economic importance over recent years, concerns about accumulation in the environment and, consequently, analysis of nanoparticles in biological material have increasingly become the focus of scientific research.

We investigated the impact of nanoscaled titanium dioxide (nTiO2) on Daphnia magna populations in a multi-generational study over six generations (F0-F5). Each generation was exposed for 21 days to nTiO2 (AEROXIDE(®) TiO2 P25, primary particle size

Late Cretaceous sea surface temperatures (SSTs) were reconstructed based on TEX 86 data from the unique high productivity upwelling system in the Southern Tethys margin, Israel. SSTs were determined from two oil shale sequences of the Santonian–ear

The Levantine high productivity system was an extensive coastal upwelling that operated in the Late Cretaceous along the SE Tethyan margin. This study focuses on the top Phosphate Member of the Mishash Formation and the Oil Shale Member (OSM) of the

The complexity of organic matter (OM) formation, its source to sink propagation and preservational process through geological time, has been the focus of extensive and interdisciplinary studies. In this study we address this issue by examining the Up

Background: On Late Cretaceous Tethyan upwelling sediments from the Mishash/Ghareb Formation (Negev, Israel),bulk geochemical and biomarker analyses were performed to explain the high proportion of phosphates in thelower part and of organic matter (O

The concentration of platinum group elements (PGE) in the environment has increased significantly in the last 20 years mainly due to their use as catalysts in automotive catalytic converters. The quantitation of these metals in different environmenta
