Petrography of exotic clasts in the soebi blanco formation, bonaire, netherlands antilles

The Paleocen e Soebi Blanco Formation in the island of Bonaire in Southeastern Caribbean has attracted the attention of geologists since 1931 when P. J. Pijpers pointed out the presence of a wide range of “foreign pebbles” in conglomerate beds. Interest was further boosted in 1986 with a Grenvillian...
