The assemblage of pelitic,
psammitic, and carbonate rocks in the Blues Brook and Malagawatch formations and the likely correlative high-grade units indicates that they formed on a passive margin in a tropical climate, as also inferred for the Brookville terrane in southern New Brunswick (Barr et al.
The Neoproterozoic Schist Greywacke Complex (SGC) is the largest domain of the CIZ which is characterized by a thick (up to 11 km) metasedimentary turbiditic sequence, consisting mostly of pelitic and
psammitic beds (Villaseca et al., 2014; Chicharro et al., 2014).
The package lies within the Company's 1035L licence, located approximately 5km to the northwest of the proposed Tete pig iron project operation and belongs to the Mid-Proterozoic aged Chidue Formation, comprising a metamorphosed package of terrestrial and shallow marine sediments dominated by
psammitic schists and marbles.
The HHC forms the hanging wall of the Main Central Thrust (MCT) and incorporates pelitic,
psammitic and quartzite sequences together with thin amphibolite and calc-silicate bands along with granitoids of various ages.
Figure 5 demonstrates results of a progressive water-saturated melting of a mixed metasedimentary source consisting of a 50:50 mixture of
psammitic and pelitic rocks from the Proterozoic Halls Creek sedimentary sequence, Kimberley region, Australia.
the Monotonous group with migmatites and gneisses of pelitic to
psammitic composition, and 2.
The Bras d'Or terrane is characterized by three main rock associations: metamorphic and igneous rocks, comprising gneiss formed at high metamorphic grade but relatively low pressure of metamorphism from pelitic to
psammitic protoliths, and incorporating thin layers of marble and amphibolite; lower metamorphic grade dominantly clastic metasedimentary rocks, but also including minor calcareous and mafic components; and a suite of late Neoproterozoic calc-alkaline plutons and associated volcanic rocks (Raeside and Barr 1992).
The Bendigo reefs comprise sub vertical lodes in
psammitic or semi-psammitic schist.
