Earthworm granules: A model of non-classical biogenic calcium carbonate phase transformations.

Different non-classical crystallization mechanisms have been invoked to explain structural and compositional properties of biocrystals. The identification of precursor amorphous nanoparticle aggregation as an onset process in the formation of numerous biominerals (crystallization via particle attachment) constituted a most important breakthrough for understanding biologically mediated mineralization. A comprehensive understanding about how the attached amorphous particles transform into more stable, crystalline grains has yet to be elucidated.

Diagenetic and Biological Overprints in Geochemical Signatures of the Tertiary Layer (Brachiopoda): Assessing the Paleoclimatic Interpretation.

Variations in the geochemical signatures of fossil brachiopod shells may be due to diagenesis and/or biological processes (i.e., 'vital effects').

Mapping geosites for geoheritage management: a methodological proposal for the regional park of Picos de Europa (León, Spain).

Mapping is a basic requirement for land use management, as effective protection of nature requires a clear delimitation of the sites involved. Additionally, mapping has other benefits for the transfer of information, as long as it is a comprehensible way of information exchange. The knowledge of geoheritage (geological heritage) and how it can be incorporated into the management of natural areas is an emerging topic.
