Definition of mylonite in English: mylonitenoun ˈmʌɪlənʌɪt mass nounGeology A fine-grained metamorphic rock, typically banded, resulting from the grinding or crushing of other rocks. count noun the mylonites occur in a complex zone Example sentencesExamples - The hanging-wall mylonite consists of an interconnected muscovite and chlorite network within a quartz-rich matrix.
- Fine-grained mylonite developed in the fault corridor may have favoured aseismic deformation in the Shin volcano area.
- These mylonites are microstructurally more homogeneous than other types, and consist of very finegrained calcite that displays an elongate grain shape fabric.
- The formation and preservation of the peridotite mylonite in particular presents problems of interpretation.
- However, quarry outcrops of mainly white halitic mylonites display isoclinal folds that suggest a more impressive past.
