A GEOLOGICAL RECONNAISSANCE IN HAITI 747 
Jamaican occurrences. This is not, of course, surprising in view of 
the fact that Jamaica is but a continuation of this peninsula. 
The Eocene—Early Oligocene limestones are generally more 
finely bedded than in the central and north ranges of Haiti. The 
overlying Oligocene-Miocene series is represented in part in several 
localities—the L’Asile Valley and north of Aux Cayes, in both of 
which are found lignite deposits. 
Near Jacmel on the south coast is a formation of conglomerate 
and marls and limestones which unconformably overlie the earlier 
Fic. 8.—View of central plain of Haiti with Montagnes Noires in the distance 
limestones and in the case of the conglomerates are largely composed 
of them. ‘These beds are well stratified, are folded, and uncon- 
formably underlie the oldest elevated coral reefs (see Plate V, 
Section B). These beds may possibly be the equivalents of the 
Pliocene series of Jamaica (Manchioneal).? 
LATE TERTIARY AND QUATERNARY DEPOSITS 
Pliocene (?) beds of the central plain.—In the southerly part of 
the central plain of Haiti and resting upon the eroded edges of the 
Oligocene-Miocene sediments is a series of gravels and sands devoid 
of marine fossils. These beds, in distinction to the underlying 
series, contain many, and often well water-worn, bowlders of lime- 
stone (Fig. 8). Chert nodules from the foraminiferal limestones are
