Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

Geological Journal, EarlyView.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

Types and resource potential of continental shale oil in China and its boundary with tight oil

Petroleum Exploration and Development, 2020
Continental shale oil has two types, low-medium maturity and medium-high maturity, and they are different in terms of resource environment, potential, production methods and technologies, and industrial evaluation criteria. In addition, continental shale

Preparation and Identification of Heavy Minerals for Archaeometrical Studies: Villa of Fiumana (FC), Italy

Journal of Raman Spectroscopy, EarlyView.
This paper presents a new protocol for the laboratory preparation of archaeological samples. Ceramics that have been hand‐crafted using different sediments as raw materials were collected in a Roman Villa sited in Fiumana (FC), Italy. This method aims at concentrating and analysing heavy minerals in the 15–250 μm grain size fraction, studying the ...
