1. Sahand is made chiefly of dacite and associated felsic rocks . 2. In rare cases, felsic rocks become sulfur saturated and form sulfide segregations. 3. Between this street and Highway 11 are Felsic rocks from the Dalhousie group. 4. Pyroclastic deposits, quartz-phyric and feldspar-felsic rocks are also present. 5. During this ascent, secondary magmas were formed that generated intermediate and felsic rocks . 6. The most common felsic rock is granite. 7. Ultramafic rocks of the Hooggenoeg Formation were most likely not parental for the felsic rocks . 8. Felsic rocks have low concentrations of Sm and high Nd and therefore " low"9. The bulk of felsic rock in the Link Lake Formation occurs as subaqueous pyroclastic flow deposits. 10. On the west flank, erosion has exposed another epithermally altered felsic rock layer with gold mineralization.
