Sedimentology, biostratigraphy and diagenesis of Upper Triassic shallow–water carbonates from Japan and Russian Far East: New investigations on the Panthalassa Ocean
Year: 2020
Type: dissertation
Abstract: This thesis work has the overall objective of improving our knowledge of shallow-water carbonate systems in Panthalassa during the Late Triassic. For such purpose, this work focuses on the very first sedimentological, biostratigraphic, paleontological and diagenetic characterization of carbonates located in two distinct study areas: i) Hokkaido Island, in the northern part of Japan, and ii) the Dalnegorsk area in Russian Far East. The combination of all the sedimentological and biostratigraphic data made it possible to reconstruct precise, even speculative depositional models for each investigated system. The Dalnegorsk area was also the subject of an in–depth diagenetic study, supported by in–situ and high–precision geochemical analyzes, in order to characterize each event which impacted the carbonate system, from its deposit to its accretion. This new sedimentological, diagenetic, biostratigraphic and paleontological data permit to better constrain the environmental conditions within the vast Panthalassa ocean.
