Past, Current and Future Processes in the Earth Critical Zone
Topic Information
Dear Colleagues,
The Earth's Critical Zone (ECZ) integrates the surface and near‐surface environment where interactions between biosphere, pedosphere, hydrosphere, atmosphere, and shallow lithosphere play a fundamental role in sustaining life. In this view, there is a need to describe and model the geochemical processes of the ECZ (e.g., rock weathering, sediment soil formation, element mobility solubility in natural water) at multiple spatial and temporal scales to track the past, current and future status of ecosystems, also in relations to environmental and climate changes. The characterization of these processes allows to face global social challenges such as environmental quality, ecosystems equilibria, human health, sustainable development, availability of resources, and water use and storage. We invite contributions to this multidisciplinary topic dealing with rock weathering, sediment and soil geochemistry, hydrogeology and hydro-geochemistry and more in general Critical Zone-relevant geological processes to steward the life-sustaining ECZ in the past, in the current day and into the future. Emphasis will be given to studies that address topics about:
- low temperature mineralogical and geochemical processes in natural environments;
- isotope fractionations and element partitioning between lithosphere, pedosphere, hydrosphere, and atmosphere;
- role of the Critical Zone in achieving sustainable development goals;
- impacts of human activities on the Critical Zone processes;
- past and future trends.
Contributes emphasizing innovative methods and approaches, as well as combination of multiple techniques are welcome, and researches by young scientists are encouraged.

Abstract:Interactions between geophysical processes and geodynamics of lithosphere play a crucial role in geologic structure of the Earth's crust. The Bangui magnetic anomaly is a notable feature in the lithospheric structure of Central African Republic (CAR) resulted from the complex tectonic evolution. We present a series of maps to obtain the coherence in the geophysical data and magnetic anomaly field from integration of free-air altimetric gravity, magnetic EMAG2 Earth data, geoid EGM2008 model and topographic SRTM/ETOPO1 relief to get insights in the geodynamics of CAR region. Histogram equalization of the topographic grids was performed for partition of raster grid files into equal-area patches of data ranged by segments with relative highs and lows of the relief, and to compare the original data with equalized, normalized and quadratic models. the scripts used for cartographic data processing are presented and commented. The consistency and equalization of topography, gravity and geoid data was based using GMT modules 'grdfft' and 'grdhisteq' modules. On the presented maps, we demonstrated the correlation between the distribution of rocks with high magnetism in the central part of the anomaly, geologic fields of granites, greenstone belts, and metamorphosed basalts as rock exposures, negative Bouguer anomaly (<-80 mGal), low geoid values (< -12 m) and the elongated shape of the magnetic anomaly with extreme negative values ranging within the amplitude of -1000 to -200 nT. The fusion of the multi-source datasets in the reported work provides a new insight into the analyses of crustal thicknesses and the average density of the Earth in CAR, as well as magnitude of the magnetic fields with notable deviations caused by magnetic flux density in Bangui area related to the distribution of mineral resources.
