Ductile Shear Zones
(Elsevier, 2015)
Mylonite with a big delta mantled porphyroclast of K-feldspar in a matrix of quartz, mica and feldspar. Mylonite is derived from a porphyritic granite characterized by large K-feldspar phenocrysts (up to 20 cm long). ...

Compositional variations of syntectonic white-mica in low-grade ignimbritic mylonite
(JOURNAL OF STRUCTURAL GEOLOGY, 2005)
The Silla del Gobernador Shear Zone (SGSZ), Coastal Range of central Chile (32 degrees S), is a low-grade mylonite generated from a Triassic acidic ignimbritic protolith. Different microstructures (e.g. quarter mats and ...

Short-scale variability of the SCLM beneath the extra-Andean back-arc (Paso de Indios, Argentina): Evidence from spinel-facies mantle xenoliths
(De Gruyter, 2015-02)
Cenozoic basalts carrying ultramafic mantle xenoliths occur in the Matilde, León and Chenque hills in the Paso de Indios region, Argentina. The mantle xenoliths from the Chenque and León hills mainly present porphyroclastic ...
Fluid-present deformation aids chemical modification of chromite: Insights from chromites from Golyamo Kamenyane, SE Bulgaria
(Elsevier, 2015)
Chemical signatures of chromitites are commonly used to track the evolution of the Earth's mantle. However, chemical modification during deformation may have important implications for the interpretation of chromites' ...
Caracterización petrológica con énfasis en microestructuras aplicado a rocas milonitizadas a la altura de la quebrada Sinifaná – Antioquia
(Universidad EAFITGeologíaEscuela de Ciencias Aplicadas e Ingeniería. Departamento de Ciencias de la TierraMedellín, 2023)
The petrographic analysis and microstructural characteristics allow us to know in greater detail the mineralogy, alterations and structures associated with tectonic processes that affect the minerals in the rock. The present ...
