Fluid Injection Triggers Large‐Scale Slow‐Slip Activation of the Rocky Mountain Fold and Thrust Belt
Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Using interferometric synthetic aperture radar (InSAR) we show that hydraulic fracturing treatments near the subsurface deformation limit of the Rocky Mountain Fold and Thrust Belt produced 12 intraplate, aseismic, slow‐slip events with magnitudes Mw ${M}_{w}$ 4.71–5.06 at 1,640–2,410 m depths.

How life affects mineral formation: A reappraisal of concepts and terminology
The Depositional Record, Volume 12, Issue 4, September 2026.We present a moderately revised terminology of concepts how life may influence mineral formation. This framework would be more consistent and universally applicable. Abstract Numerous biological factors have been proposed to influence the formation of minerals under Earth‐surface conditions, but the underlying concepts are often confused due to ...
