| 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. |
| Compositionally, the turbidites are mostly feldspathic litharenites with trace amounts of serpentinite, anorthosite and mafic volcanic clasts. |
| Sienite and feldspar succeeded in our descent to the snow line, where we found a feldspathic granite. |
| Neither sample showed optical evidence for postformation alteration in the form of chloritized veins or sericitization of feldspathic minerals or micas. |
| It occurs in the various feldspars and feldspathic rocks, and in mica. |
| The MSU is modelled as being a southward plunging, lenticular body that runs parallel to, but above, the coarse grained feldspathic peridotite intrusion. |
