Complex of ultramafic rocks occurs c. 7km NW of Salem town.
The Salem Mafic-Ultramafic Complex is an ENE-WSW trending semicircular to elongate body (maximum length of 20 km) located in the Salem block of the Southern Granulite Terrane. Dunites, serpentinites, pyroxenites, wehrlite, peridotite, hornblendite, charnockite, hornblende gneiss, mafic and felsic intrusions like gabbro, amphibolite, and dolerites, quartzo-feldspathic alkaline rocks, and ultra-potassic intrusions like shonkinites and lamprophyres are the major lithounits in the SMUC.
