Locating the Carnian-Norian Boundary with Stable-isotope and Conodont Biostratigraphy, Martin Bridge Fm., southern Wallowa Mountains, Oregon: Link to GSA Abstract



Current research in the LaMaskin lab falls into two broad categories:


(1) Using sedimentary provenance to understand the evolution of plate margins and continental sediment dispersal systems, and


(2) Using stable isotope stratigraphy to establish a chronostratigraphic signature for the Late Triassic, Carnian-Norian Boundary Interval
