Abstract:
Petrographic and petrochemical study of igneous rocks from the Sierra Leone Rise indicate that trachytes, trachyandesites, trachybasalts, and tuffs derived from them occur there. K-Ar age of these rocks is 36-43 million years. Alkalic igneous activity is associated with activity of hot spots.
