The ECS TS team, and their activities between GAs

As member of the EGU Tectonics and Structural Geology (TS) Early Career Scientist (ECS) Representative team, and with the outlook of the first hybrid EGU General Assembly (GA), I take the opportunity to highlight some of the activities and news of the ECS TS team. The ECS TS team has been very active all year …[Read More]

Features from the Field: Dikes and Sills

dyke and sill in Dalradian quartzite

Volcanoes are everywhere along plate margins and on hot spots on the planet’s surface. Just in the past 2 years, we have witnessed enormous explosive eruptions such as that of the Hunga Tonga volcano which released an amount of energy equivalent to hundreds of atomic bombs, and massive lava flows, as at the Cumbre Vieja …[Read More]

TS Must-Read – Brun (1999): Narrow rifts versus wide rifts: inferences for the mechanics of rifting from laboratory experiments

In 1999 Jean-Pierre Brun published his Must-Read paper about rifting, in which he reviews fifteen years of laboratory experiments at Geosciences Rennes. In a brief introduction the paper reminds the reader of the two main rift types: narrow rifting as the preceding stage for continental break-up, and wide rifting that occurs after cessation of convergence. …[Read More]

TS Must Read – Scholz (1998): Earthquakes and friction laws

Scholz (1998) is the “must-read” review article about rate- and state- variable laws of rock friction. The article is a robust introduction to the state-of-the art of the discipline at the end of the past century and should be considered of particular interest for students and/or early career scientists. In spite of its relative simplicity, …[Read More]

TS Must-Read – Cowie (1998) A healing-reloading feedback control on the growth rate of seismogenic faults

This study provides a simple numerical model of fault rupture that describes the development of fault systems from the initial nucleation of numerous small faults to the localisation of deformation into few major faults. The model presented is based on two main considerations: first, earthquakes cause stress changes that can either advance or delay failure …[Read More]

TS Must-Read – Caine et al., 1996 Fault zone architecture and permeability structure

Caine et. al. (1996) is a cornerstone paper which describes, compares and quantifies brittle fault zones and their permeability (fluid flow) properties from observations. Doing so, the paper initiates the accumulation of information on the permeability of brittle fault zones described previously (Randolph and Johnson 1989; Scholz 2019; Byerlee 1993). The study begins by defining …[Read More]
