Marieke Dechesne

I am a geologist in the Geosciences and Environmental Change Science Center at the USGS. I am trained in stratigraphy and sedimentology and my current research focuses on basin analysis, paleogeography and the interaction between tectonic signals, sedimentation and climate.

n the past several years I have worked on the Laramide synorogenic basin fill of the Denver Basin with both the Denver Museum of Nature & Science and the Colorado Geological Survey, before moving focus to the 'back-side' of the Front Range where I now study the axial Colorado Headwaters Basin (North Park-Middle Park), the Hanna Basin and South Park for the USGS Cenozoic Evolution of the Southern Rocky Mountains project.  From these basin fill sequences I am trying to reconstruct uplift history and the overall paleogeographic evolution in this region. I am incorporating as many parameters as possible, like outcrop observations, subsurface data (well-logs and seismic), fossil information, paleobotany, palynology, radiometric dating, etc. to develop a rigid 3D- (4D?) stratigraphic framework that reveals clues about timing of  uplift, sediment accumulation rates, paleo-environments and paleogeography.

Peri-Gondwanan sediment in the Arkoma Basin derived from the north: The detrital zircon record of a uniquely concentrated non-Laurentian source signal in the late Paleozoic

During the assembly of Pangea, peri-Gondwanan terranes collided with the eastern and southern margins of Laurentia and brought with them unique detrital zircon U-Pb signatures. Discriminating between individual peri-Gondwanan terranes in the detrital record is difficult due to their similar geologic histories. However, characterization of this provenance is critical for understanding late Paleozoi

Influence of inherited structure on flexural extension in foreland basin systems: Evidence from the northern Arkoma basin and southern Ozark dome, USA

Extensional faults are key components of foreland basin systems. They form within the upper crust in response to flexure of the lithosphere and accommodate subsidence within the foredeep and forebulge depozones. Such faults are excellent proxies for orogenic system evolution and control the distribution of natural resources and hazards. However, the spatiotemporal evolution of flexural extension h
