Abstract: Abstract Multiple episodes of deformation during the tectonic evolution of orogenic belts and ancient subduction-accretion complexes cause obfuscation of primary block-in-matrix fabric of melanges, and thereby making the recognition of their tectonic, sedimentary or diapiric… read more here.

DOI: 10.1029/2024tc008456
Abstract: Most mélanges in exhumed subduction‐accretion complexes are polygenetic, recording significant information about the nature of geological processes during their formation. Here, we apply micro‐chemical analysis and illite K‐Ar dating to constrain the deformation mechanism and… read more here.
