GEOLOGY OF SURINAME
The Ston Formation in western Suriname, consisting of metaquartzar enites and conglomerates, has been correlated with the Rosebel Formation, but differs from this formation in its much more mature composition and open style of folding. Moreover, it is conformably overlain by the Dalbana Forma tion metarhyolites (see below) and hence might better be correlated with the Muruwa .
