The influence of the cataclastic matrix on the petrophysical properties of deformation bands in arkosic sandstones

This study investigates how the intensity of the cataclasis deformation mechanism influences petrophysical properties, such as pore diameter, grain size, porosity, and permeability, in deformation bands of arkosic sandstones and conglomerates affected by normal fault zones in the Rio do Peixe Basin,...

Zusammenfassung:This study investigates how the intensity of the cataclasis deformation mechanism influences petrophysical properties, such as pore diameter, grain size, porosity, and permeability, in deformation bands of arkosic sandstones and conglomerates affected by normal fault zones in the Rio do Peixe Basin, Brazil. We analysed in detail the cataclastic matrix within the deformation bands, defined as the amount of fine particles (
