Richard O Lease, Ph.D.
Richard Lease is a Research Geologist with the Alaska Science Center in Anchorage, AK
Richard conducts framework geology research on Alaska sedimentary basins, mountain belts, landscapes, and paleoclimate. His research typically utilizes the fields of stratigraphy, tectonics, geomorphology, and geochronology. His past research focused on tectonic-climatic-geodynamic interactions during growth of the Tibetan Plateau and Central Andes.

Magnetostratigraphy of the Neogene Chaka basin and its implications for mountain building processes in the north-eastern Tibetan Plateau
Magnetostratigraphy of sedimentary rock deposited in the Chaka basin (north‐eastern Tibetan Plateau) indicates a late Miocene onset of basin formation and subsequent development of the adjacent Qinghai Nan Shan. Sedimentation in the basin initiated at ∼11 Ma. In the lower part of the basin fill, a coarsening‐upward sequence starting at ∼9 Ma, as well as rapid sedimentation rates, and northward pal

Signatures of mountain building: Detrital zircon U/Pb ages from northeast Tibet
Although detrital zircon has proven to be a powerful tool for determining provenance, past work has focused primarily on delimiting regional source terranes. Here we explore the limits of spatial resolution and stratigraphic sensitivity of detrital zircon in ascertaining provenance, and we demonstrate its ability to detect source changes for terranes separated by only a few tens of kilometers.
