Primitive Cretaceous island-arc volcanic rocks in eastern Cuba: the Téneme Fromation
The Téneme Formation is located in the Mayarí-Cristal ophiolitic massif and represents one of the three Cretaceous volcanic Formations established in northeastern Cuba. Téneme volcanics are cut by small bodies of 89.70 ± 0.50 Ma quarz-diorite rocks (Río Grande intrusive), and are overthrusted by ser...
