Stable isotope tempestology of tropical cyclones across the North Atlantic and Eastern Pacific Ocean basins Open
Tropical cyclones (TCs) are one of the major natural hazards to island and coastal communities and ecosystems. However, isotopic compositions of TC‐derived precipitation (P) in surface water (SW) and groundwater (GW) reservoirs are still l…

Modern Microbial Carbonates Deposits in South America: New insights of sedimentation and diagenesis in alkaline lakes. Open
The sedimentation in the alkaline lakes could be understood as a product of intrinsic and extrinsic factors’ interaction, where both can exert influence with alternating or progressive predominance due to the large-scale geochemical …

Detrital isotopic record of a retreating accretionary orogen: An example from the Patagonian Andes Open
U-Pb zircon geochronology and isotopic records have played an influential role in our understanding of convergent margin dynamics. Orogenic cyclicity models link tectonic regimes with magmatic isotopic signatures in advancing orogens, rela…
