Albite is the dominant mineral in foliated felsites, in chlorite schist
, in carbonate-rich albitite, and in large-scale albitite bodies [23,50].
Beigu mountain tunnel is constructed in mica schist, chlorite schist
, and leptynite (Figures 2(b), 2(c), and 2(d)).
The Burji-La Formation consists of meta- volcanic rocks (greenschist) of basalt to basaltic- andesitic composition and grey to black slate in the study while dark grey phyllite, thin bedded argillaceous limestone, volcanoclastic siltstone, feldspathic sandstone, quartz schist and chlorite schist
have also been reported in this formation in other places (Robertson and Collins, 2002).
In all cases, the exposed basement rock is metasedimentary rock of the McMillan Flowage Formation, occurring as phyllite in Christopher MacLeod Brook, chlorite schist
in Baddeck River, and chlorite-muscovite schist in Big Glen Brook and at least two unnamed tributary brooks draining into it.
The figure is of green chlorite schist
, (6) and 120 centimetres tall.
Fragments of bowls made of a soft stone called chlorite schist
have been found, and beads made of cornelian and glass.
The pegmatite, which consists of three separate limbs, intrudes a wide zone of chlorite schist
that sits between rusty metavolcanic biotite-feldspar schist and the end of the ultramafic sill (Garland, 2004).
Metasediments include amphibolites epidote chlorite schist
pillitic schist talc-carbonate schist graphitic schist and slates.
In hole SLRC11_001 the graphite is present as two zones separated by a chlorite schist
(possible shear zone and termed marker unit).
At the Western Queen, the geology is steep west dipping and comprises of intercalated sheared amphibolites of mafic to ultramafic composition with thin iron formation horizons, komatiitic basalt, dolerite sills, and talc chlorite schists
. Later dolerite and pegmatitic felsic intrusives cut across the amphibolites and gold mineralisation.
