Geochemical mapping by unmixing alluvial sediments: an example from northern Australia

open access: yes, 2023
Alluvial sediments have long been used in geochemical surveys as their compositions are assumed to be representative of areas upstream. Overbank and floodplain sediments, in particular, are increasingly used for regional to continental-scale geochemical ...

Geochemical background and threshold for 47 chemical elements in Slovenian topsoil

open access: yesGeologija, 2019
Geochemical background and threshold values need to be established to identify areas with unusually high concentrations of elements. High concentrations are caused by natural or anthropogenic processes. The

Distribution of Heavy Metals and Ecological Risk of Soils in the Typical Geological Background Region of Southwest China

open access: yesYankuang ceshi, 2021
BACKGROUND 22.3% of the cultivated land in southwest China has excessive heavy metal content. The widely distributed Emeishan basalt and carbonate rocks in the region are considered to be the main source of heavy metals in the soil. At present, the level

Geochemical barriers as structural components of the geochemical systems evolution [PDF]

open access: yesE3S Web of Conferences, 2019
The term “geochemical barrier” (GCB) has been widely used in the Russian geochemical literature as a key concept of the distribution of elements and substances theory (incl. pollutions)although in the world research practice this term is not particularly represented.
