Medium- to high-grade pelitic schist that contains subordinate quartzite, quartz schist, calc-silicate rocks and calc-schist, marble, amphibolite, graphitic schist, and augen gneiss interlayers. Compared to unit PzPxyqs, this unit contains less quartzite and quartz schist, more marble interlayers, and is of generally higher grade; however, it may have strong similarities in lithology, polymetamorphic history, and metamorphic grade with unit PzPxyqs. The contact with PzPxyqs was interpreted as a thrust fault by Foster and others (1983) in the Circle quadrangle and was also locally mapped as such by Smith and others (1994). In the Eagle quadrangle, unit is closely associated with metaplutonic rocks of unit MDag, possibly as roof pendants to the original plutons
