My Research
My research deals with Upper Triassic shallow water carbonates of the panthalassan realm and is part of the REEFCADE project (REEF and carbonate buildup development).
This project aims to improve our understanding of reef and carbonate
buildup development during the Upper Triassic and my PhD mainly focuses
on the mid-oceanic carbonate sedimentation in the western part of the
Panthalassan ocean. We work on several localities belonging to the
Sambosan Accretionary Complex (SAC) in southwestern Japan (Shikoku and
Kyushu islands).
The SAC is composed of several lithological units that mainly represent
remains of a mid-oceanic atoll-type seamount carbonate systems, reworked
in a subduction-generated accretionary complex. Therefore, the SAC
provides useful data concerning the Upper Triassic mid-oceanic
shallow-water environments that remain poorly understood.
I perform field investigations as well as sedimentological and
micropaleontological analysis in new areas all along this complex,
mainly in eastern Shikoku.
Special emphasis will be devoted to the improvement of the
chronostratigraphy of the Sambosan Upper Triassic shallow-water
limestones by using conodont analysis. Based on our previous data, the
most promising microfacies for conodont extraction are sampled and
systematically processed.
The ultimate goal of these studies is the comparison, and possibly the
correlation, of reefal biota and depositional settings of the SAC with
coeval localities in western (Japan, Philippines, eastern Russia) and
eastern (USA, British Columbia) parts of the Panthalassa respectively.
This comparison will allow us to better constrain palaeogeographical
models and to compile global stratigraphic charts for the Upper
Triassic.
Additionally, this type of research has been and will always provide
unique opportunities for taxonomic revisions, especially in the
systematic of foraminifers.
