Abstract

A U-Pb analysis of seven zircon fractions from a granulitic pebble in the Late Paleocene and/or Eocene fluviatile Soebi Blanco conglomerate on Bonaire, Netherlands Antilles (southern Caribbean borderland) indicates that the rock has been derived from a Precambrian basement with an age of approximately 1150 Ma. Such basement rocks do not occur on Bonaire. The nature of the conglomerate testifies to derivation from a nearby topographic high. It is suggested that the source area was located in the Guajira area, implying an eastward migration of Bonaire of some 300 km relative to the South American mainland since the beginning of the Tertiary.
