Virtually unaltered amphibolites may have subordinate, late, randomly oriented biotite laths overgrowing the main foliation.From theCambridge English Corpus
It displays different habits, ranging from phenocrysts to small grains interstitially distributed between plagioclase laths.From theCambridge English Corpus
They investigated apparent dihedral angle populations generated by randomly oriented grains of differing shape, ranging from spheres to cubes and laths.From theCambridge English Corpus
Lath-shaped plagioclase is albite in composition and pyroxene has been mainly replaced by tremolite.From theCambridge English Corpus
Occasionally the pyroxene occurs also as poikilitic plates (3-5 mm) enclosing plagioclase laths.From theCambridge English Corpus
The planar fabric is defined by the preferred orientation of amphibole laths and compositional layering.From theCambridge English Corpus
However, plagioclase laths are poorly aligned and biotite is randomly oriented.From theCambridge English Corpus
Of the fluoroapatite, a subset of crystals islathshaped, 5-10 m in size.From theCambridge English Corpus
Euhedral laths of zoned plagioclase define a distinct igneous lamination.From theCambridge English Corpus
The plagioclase laths are believed to represent relict plagioclase phenocrysts in the volcanic protolith.From theCambridge English Corpus
Phenocrysts of plagioclase, hornblende and clinopyroxene are embedded in a very fine-grained groundmass of plagioclase laths, fine hornblende prisms, and some biotite and augite crystals.From theCambridge English Corpus
The authigenic nature of the illite is evident from its fibrous,lath- or lettuce-like habit.From theCambridge English Corpus
Typically, plagioclase occurs as laths in the groundmass, 0.1-0.5 mm in size.From theCambridge English Corpus
