Example sentencesExamples
- Neither sample showed optical evidence for postformation alteration in the form of chloritized veins or sericitization of feldspathic minerals or micas.
- The coarse-grained sandstone matrix is dominated by feldspathic litharenites with 50-70% quartz, 2-5% K-feldspar and 10-15% plagioclase.
- The turbidites and their migmatized schistose equivalents overlie the grey feldspathic arenites but it is unclear whether this relationship is stratigraphic or the result of tectonic stacking.
- Compositionally, the turbidites are mostly feldspathic litharenites with trace amounts of serpentinite, anorthosite and mafic volcanic clasts.
- The lower member is dominated by a thick basal dolomite and passes transitionally upwards into the psammitic upper member, which is largely feldspathic schist and quartzite.
