A Giant Rockslide on a Bed of Steam

by Peter van der Beek 25 May 202324 May 2023

Detailed observations of the giant Sevier gravity slide in Utah show that the exceedingly low basal friction required for its rapid emplacement was developed by trapped thermally pressurized fluids.

Probing the Sedimentology of a Continental Megathrust

by Peter van der Beek 6 September 202222 December 2022

Detailed analysis of sediments covering the Main Frontal Thrust in Nepal show how climate-driven baselevel changes affect sedimentation and should be considered when inferring thrust activity.

Searching for Earth’s Oldest Rocks in its Youngest Deposits

by Peter van der Beek 18 August 202225 August 2022

By sampling and analyzing zircons from glacial eskers dating from about 20,000 years ago, the extent of the oldest known rocks on Earth can be better mapped and constrained.

The Great Unconformities?

by Peter van der Beek 3 August 20219 December 2022

New thermochronology data and thermal history modeling from the Canadian Shield show that the Great Unconformity formed there later than elsewhere in North America and may represent another event.
