General geology and geochemistry of the Lokpanta Formation oil shale, Nigeria [PDF]
Oil Shale, 2021 A detailed geochemical and mineralogical study was carried out on the Lokpanta oil shale (OS), Nigeria. Samples from three drill cores and several outcrops were studied in order to understand OS general geochemistry and reconstruct tectonic and ...

High-resolution two-dimensional quantitative analysis of phosphorus, vanadium and arsenic, and qualitative analysis of sulphide, in a freshwater sediment. [PDF]
, 2008 Recently introduced techniques that can provide two-dimensional images of solution concentrations in sediments for multiple analytes have revealed discrete sites of geochemical behaviour different from the average for that depth (microniches).

Chromium Cycling in Redox‐Stratified Basins Challenges δ53Cr Paleoredox Proxy Applications
Geophysical Research Letters, 2022 Chromium stable isotope composition (δ53Cr) is a promising tracer for redox conditions throughout Earth's history; however, the geochemical controls of δ53Cr have not been assessed in modern redox‐stratified basins.
