The ratio ofamphiboleto biotite is markedly lower than in the core.From theCambridge English Corpus
These are defined by the presence of greenamphibole+ titanite, and colourless hornblende, respectively.From theCambridge English Corpus
Data from theamphibolesample do not define an age.From theCambridge English Corpus
This is conspicuous for biotite andamphibolecrystals but less so in the strongly altered feldspar crystals.From theCambridge English Corpus
It is composed of biotite andamphibolegranodiorites, with slightly deformed biotites and locally weakly altered to chlorite.From theCambridge English Corpus
The pale layers are predominantly composed of plagioclase with granoblastic texture, zoisite, quartz, blue-greenamphiboleand accessory biotite and rutile.From theCambridge English Corpus
Lineation is marked by stretching of the amphiboles around the epidote mineral.From theCambridge English Corpus
This sample is composed of plagioclase (c. 40 %), greenamphibole(c. 30 %), brown biotite (c. 15 %), microcline (c. 10 %) and quartz (< 5 %).From theCambridge English Corpus
The neoblastic garnets are intergrown withamphibole-plagioclase-quartz symplectites.From theCambridge English Corpus
It solidifies together with the outwards-growing crystals, forming the mafic shell made up of biotite,amphiboleand plagioclase.From theCambridge English Corpus
A succession of mineral reactions is shown by inclusions in and overgrowths on garnet, pyroxenes and amphiboles.From theCambridge English Corpus
