Quantitative paleoenvironmental and paleoclimatic reconstruction using paleosols
Nathan D. Sheldon,Neil J. Tabor +1 more
TL;DR: Paleosols (fossil soils) are preserved throughout the geologic record in depositional settings ranging from alluvial systems to between basalt flows as mentioned in this paper, and a variety of semi-quantitative and quantitative tools have been developed to examine past weathering and pedogenesis, and to reconstruct both paleoenvironmental and paleoclimatic conditions at the time that the paleosols formed.

Impact of stylolitization on diagenesis of a Lower Cretaceous carbonate reservoir from a giant oilfield, Abu Dhabi, United Arab Emirates

TL;DR: In this paper, the authors demonstrate that stylolitization plays a crucial role in fluid flow and diagenesis of carbonate reservoirs during basin evolution, and the flanks of the oilfield (water zone) display more frequent presence and higher amplitude of stylolites, lower porosity and permeability, higher homogenization temperatures and more radiogenic composition of carbonates compared to the oil zone.

Metamorphic and basin fluids in quartz–carbonate–sulphide veins in the SW Scottish Highlands: a stable isotope and fluid inclusion study
TL;DR: In this paper, the authors identified two distinct mineralising fluids from fluid inclusion and stable isotope studies, high temperature (>350°C) quartz-precipitating fluids were moderately saline (4.0-12.7 wt.

Crystal Structures of Clay Minerals and their X-ray Identification
G. W. Brindley,G. Brown +1 more
TL;DR: In the years 1930-1950 clay mineral identification involved mainly a combination of X-ray powder diffraction and chemical analysis with some assistance from other techniques, notably differential thermal analysis.

The use of bromine pentafluoride in the extraction of oxygen from oxides and silicates for isotopic analysis
TL;DR: In this paper, a technique was developed in which bromine pentafluoride was used as a reagent for quantitative liberation of oxygen from oxides and silicates, and the results of isotopic analyses were compared with measurements made in other laboratories by other procedures.
