Most serpentinite rocks are cross-cut by carbonate and quartz-carbonate veins with different thickness. This study focuses on petrographic, mineralogical, geochemical, and isotopic analysis of the carbonate veins embedded in serpentinite rocks, collected at the Fosso Arcangelo site and at the Pietrapica quarry (Calabria-Lucanian boundary). The paragenesis of the carbonate veins from the Fosso Arcangelo site is dominantly made by calcite and aragonite with minor amount of rhodochrosite. In quartz-carbonate veins from Pietrapica quarry, dolomite, Mg-calcite, quartz, with minor ankerite were observed. The ?13CV-PDB isotope ratios of carbonates in the carbonate veins are in the range from +2.16? to -3.66? and corresponding ?18OV-SMOW values are between +15.02? and +21.53?. The ?13CV-PDB values of carbonates in quartz-carbonate veins are in the range from -3.60? to -1.78? and the corresponding ?18OV-SMOW average value is around +21.3?. The results suggest that the carbonate at both site occurredunder the same environmental conditions from crustal-derived and low-moderate temperatures hydrothermal fluids having different chemical composition. eng Genesis of carbonate-rich veins in the serpentinites at the Calabria-Lucania boundary (southern Apennines) journal article URL https://docta.ucm.es/bitstreams/fb46cce9-3324-4526-9b71-56791828a766/download File MD5 4df615f24e4a71ba199e17e511a2eb69 2446269 application/pdf Genesis of carbonate-rich veins in the serpentinites.pdf URL https://docta.ucm.es/bitstreams/b3cf38e8-088b-427b-9bd0-209a145a0d21/download File MD5 3cbc089e2499312257d300227b359df8 36446 text/plain Genesis of carbonate-rich veins in the serpentinites.pdf.txt
