Evaluation of bricks durability using destructive and nondestructive methods (DT and NDT)

open access: yesMateriales de Construccion, 2003
We have studied the physical-mechanical behaviour of solid bricks treated with consolidants and/or water-repellents in accelerated aging tests to determine their durability.

Tidal versus fluvial point bars: Key features from the integration of outcrop, core and wireline log information of Triassic examples

open access: yesThe Depositional Record, Volume 10, Issue 5, Page 793-820, November 2024.
Abstract The Triassic red beds of the Tabular Cover of the Iberian Meseta are an excellent reservoir outcrop analogue, a direct consequence of high‐quality exposures, which offer exceptional three‐dimensional outcrops, as well as a wide variability of depositional environments.

STRATIGRAPHY AND DIAGENESIS OF THE THAMAMA‐B RESERVOIR ZONE AND ITS SURROUNDING DENSE ZONES IN ABU DHABI OILFIELDS AND EQUIVALENT OMAN OUTCROPS

open access: yesJournal of Petroleum Geology, Volume 47, Issue 4, Page 395-430, October 2024.
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 ...

Carboniferous Barrovian to Permian Buchan‐type metamorphic cycles in the Mongolian Altai Zone: Implication for pressure cycles in accretionary orogens

open access: yesJournal of Metamorphic Geology, Volume 42, Issue 7, Page 979-1033, September 2024.
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

O uso de pseudosseções em Petrologia Metamórfica: conceitos básicos e aplicações, com ênfase em pelitos

open access: yesGeologia USP. Série Científica, 2022
O uso de pseudosseções em trabalhos voltados para Petrologia Metamórfica tem se tornado cada vez mais comum nos últimos 20 anos em razão de uma série de fatores, entre eles o avanço das técnicas de análise química mineral usando microssonda eletrônica e
