TS Must-Read – Fossen and Cavalcante (2017): Shear zones – A review

The Must-read team September 4, 2025

Haakon Fossen and Geane Carolina G. Cavalcante published their seminal review on the topic of shear zones in 2017 in the journal Earth-Science Reviews. The work summarizes the scientific findings on the development and quantification of ductile shear zones sincefrom the the 1960s up to recently. It describes the fundamental aspects of the initiation and …[Read More]

TS Must-Read – Fossen and Tikoff (1993): The deformation matrix for simultaneous simple shearing, pure shearing and volume change, and its application to transpression-transtension tectonics

The Must-read team January 31, 2022

With their milestone article in Journal of Structural Geology (Fossen and Tikoff, 1993)⁠ and its companion article in Tectonophysics (Tikoff and Fossen, 1993)⁠, the authors marked a step forward for the quantification of strain in the deep crust. These articles popularized a new approach, the deformation matrix. An easy solution to quantify strain in finite …[Read More]
