Ichnology and geochemistry: an integrated approach to early marine diagenesis in the Arabian Gulf
DownloadSpring 2024
Neoichnological studies in carbonate-dominated tropical latitudes are sparse. Moreso, the coupling of diagenetic research utilizing ichnology has been largely limited to ancient successions. This thesis combines geochemical analyses with modern ichnological observations to better understand the...
