We review published studies characterizing the Thamama‐B reservoir zone in the upper Kharaib Formation (late Barremian) in Abu Dhabi oilfields and at outcrops in Oman. Available data for oxygen and carbon isotope compositions, fluid inclusion measurements, cement abundance and formation water composition are interpreted in terms of a paragenetic model ...

Las rocas plutónicas de la Hoja, así como las filonianas que les acompañan, se consideran ligadas al ciclo hercínico con la excepción de algunas formaciones de cuarzo que aparecen en fracturas tensoriales claramente posthercínicas (y no tardihercínicas).

Abstract In the Altai Accretionary Wedge, several periods of Barrovian‐ and Buchan‐type metamorphic cycles were dated from Ordovician to Permian. However, the timing and link between these cycles are not clear, and their causes are debated. In order to contribute to the understanding of Barrovian‐ to Buchan‐type evolution of the accretionary wedges, we

How the Sima de los Huesos was won
Abstract Although the first discovery of a human fossil in the Sima de los Huesos took place in 1976, systematic excavations did not begin there until 1984. Since then, this site has been continuously excavated in month‐long camps. The site is dated by different radiometric techniques to between 430,000 and 300,000 years ago.
