Abstract

Rb-Sr investigations revealed an age of 85.1 ± 0.5 Ma (Coniacian-Santonian) for the northwestern part of the tonalitic batholith on Aruba, and an age of 70.4 ± 2.0 Ma (Maastrichtian) for the remaining part. The dates are interpreted in terms of an episodic intrusion of the batholith. It is discussed that the two episodes of tonalitic magmatism belong to two different tectonic-magmatic phases in the geologic evolution of the Caribbean region.
