In some cases, crenulations, kink bands in chlorite, and weak to intense deformation superimposed to the main foliation of the rock, developing a mylonitic
texture characterized by the presence of thin strips of actinolite and elongated quartz, intercalated with thicker bands quartz and plagioclase.
During intra-oceanic subduction various parts of the subducted plate were accreted to the base of the overriding slab and subjected to a temperature between about 9001000 C forming mylonitic
peridotite and then continued downwards to form the sub-ophiolitic metamorphic rocks.
metabasite from the same location as LF1.
El Picacho Metagabbros show greenschist-- to lower-amphibolite-facies parageneses, conspicuous mylonitic
structure, no relation to metasediments, and spatial association to the Medellin Dunite.
Local bands of mylonitic
recrystallization are common, particularly near boundaries between units of differing competencies.
Typical fabrics include a weak to strong foliation trending ENE, gradational contacts and metasomatic changes to pegmatoid and mylonitic
The Province of Sevilla is bounded on the east by the Seville lineament and on the west by the Guachaca fault; it is composed of mylonitic
granitoids and amphibole and micaschists of Paleozoic age (Tschanz et al, 1969, 1974; Cardona et al, 2006).
The intermediate belt (Seville province) represents a polymetamorphic complex that includes gneisses and schists of Paleozoic age with Permian mylonitic
granitoids (Tschanz et al.
The foliated peridotite grades downward into basal peridotite displaying mylonitic
to porphyroclastic textures.
The provenance of sedimentary and volcanic clasts in the central part of the conglomeratic sequence is not clearly related to local basement sources, which are variably mylonitic
metamorphic and plutonic rocks (Force and Barr 2006).
These aquifers are constituted by alluvial formations with thicknesses of up to several hundreds of meters, delimited in their base by mylonitic
rocks of the Sierra Juarez from the Mesozoic and metamorphic rocks from the Precambrian.
