ROCK DEFORMATION LAB

The Rock Deformation lab at the Ben-Gurion University of the Negev study the dynamics of Earth, from the shallow crust to the deep mantle.

 

Experiments and microstructural analysis of natural samples are used to explore the micro-scale underlining physics of deformation of Earth and planetary materials with implications to the large-scale Earth's dynamics.

THE RESEARCH

Natural or experimentally induced yield of rocks can be the focal point of research, whether considering the study of faults and slip along faults during earthquakes (unstable, seismic event) or deformation during fault creep (stable, aseismic slip). These phenomenon, their controling mechanism/s, and resulted mark on the rock microstructures (textures) are our way in understanding the strength and mechanical behavior of the rocks and Earth layers beneath us. Research questions can be related to the study of earthquakes and earthquakaes hazards, such as what makes a fault stable or unstable, what conditions will generate the fault structure that we observe in the field? While other researach question can be related to the way the system of plate tectonics evolve, such as what are the microstructural, chemical, and rheological ('the study of flow') properties of mantle flow? or what control the properties and evolution of the continental strong and stable part of the mantle?

We're looking for motivated students to join our team! If you're interested please contact us.

THE LAB

The new 'Griggs' type solid-medium apparatus for deformation can simulate conditions of down to ~100 km depth into the Earth with the conditions of high temperatures (~1300 C) and pressures (~3 GPa). The apparatus was installed at the Rock Deformation lab at Ben-Gurion University February 2020.
