Petrographic analysis of eight CM carbonaceous chondrites (EET 96029, LAP 031166, LON 94101, MET 01072, Murchison, Murray, SCO 06043, QUE 93005) by electron imaging and diffraction, and X-ray computed tomography, reveals that six of them have a petrofabric defined by shock flattened chondrules. With the exception of Murchison, those CMs that have a strong petrofabric also contain open or minera...

Abstract Evidence of impact‐induced compaction in the carbonaceous chondrites, specifically CMs and CVs, has been widely investigated utilizing microscopy techniques impact experiments. Here, we use high‐resolution photography large area electron backscattered diffraction (EBSD) mapping analyses tandem, to explore effects at both meso‐ micro‐scales Allende CV3.6 chondrite. Macro‐scale images a ...

Heterogeneities in the magnetic signature along intraplate shear zones complicate their correlation with physical processes that are involved geodynamic evolution of megathrusts. Isolating preferred orientation different minerals may provide insights into faulting processes, tectonics, and strain partitioning. Studies exhumed analogs fundamental to constrain variations properties respect a cont...
