Ramon Mercedes-Martín, PhD
Carbonate sedimentologist
ABOUT ME
I am a process-sedimentologist currently developing new geochemical, hydrochemical and experimental approaches to better understand the sedimentology, stratigraphic architecture and diagenesis in carbonate-dominated geosystems (both in natural and Anthropogenic environments).
I am particularly interested in quantifying the biogeochemical processes governing the multi-scale heterogeneity of non-skeletal carbonate deposits using field, petrographic, laboratory and numerical modelling.
One of my prime goals is to obtain more quantitative constraints that can help us to decipher the paleobiological, paleoenvironmental, and paleoclimatological significance of non-skeletal carbonate factories across diverse temporal and spatial scales.
Looking for new academic/ research opportunities in Europe. Open to transdisciplinar collaborations worldwide.
