GeoRoundup: the highlights of EGU Journals published during November!

Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we will be putting the journals that publish science from those Divisions at the top of the Highlights roundup. For November, the Divisions we are featuring are: Energy, Resources and Environment (ERE), Nonlinear Processes in Geoscience (NP) and Seismology (SM). They are served by the journals: Geoscientific Model Development (GMD), Earth System Dynamics (ESD), Nonlinear Processes in Geophysics (NPG), Weather and Climate Dynamics (WCD), and Solid Earth (SE).

 

Featured highlights

Solid Earth:

Deformation-enhanced diagenesis and bacterial proliferation in the Nankai accretionary prism – 1 November 2021

Sediments accumulated in accretionary prisms are deformed by the compression imposed by plate subduction. Here we show that deformation of the sediments transforms some minerals in them. We suggest that these mineral transformations are due to the proliferation of microorganisms boosted by deformation. Deformation-enhanced microbial proliferation may change our view of sedimentary and tectonic processes in subduction zones.

 

Dating folding beyond folding, from layer-parallel shortening to fold tightening, using mesostructures: lessons from the Apennines, Pyrenees, and Rocky Mountains – 29 November 2021

This paper aims to illustrate how the timing and duration of contractional deformation associated with folding in orogenic forelands can be constrained by the dating of brittle mesostructures observed in folded strata. The study combines new and already published absolute ages of fractures to provide, for the first time, an educated discussion about the factors controlling the duration of the sequence of deformation encompassing layer-parallel shortening, fold growth, and late fold tightening.
