Stratigraphy. The succession of rock units of Cuba is given in the 

 chart of Fig. 42.3. The oldest rocks are a metamorphic complex which 

 crops out in the eastern Oriente Province, in two places in central Cuba, 

 and on the Isla de Pinos. It is included in the middle Jurassic by Butterlin 

 (1956) but may be older (Taber, 1934). The complex in the Trinidad 

 Mountains consists of limestones and dolomites and a carbonaceous, chlor- 

 itic, mica schist. Quartz-garnet-mica schist and epidote and talc schists 

 are also noted (Hill, 1959). No fossils were found. Serpentines of two 

 types occur in the complex, a nodular one derived from periodotite and 

 a fine-grained one derived from microgabbro. The one derived from 

 microgabbro is older and has been affected by two movements, one pre- 

 serpentinization and one postserpentinization. The rocks are isoclinally 

 folded. 



The Jurassic and Lower Cretaceous strata are irregularly treated in the 

 literature, but now it is believed that a continuous sequence exists from 

 the Middle Jurassic to the Tertiary. According to C. W. Hatten of Standard 



Oil of California ( personal communication ) the northern succession from 

 the Vinales limestone through the Cretaceous is a carbonate facies closely 

 related to the Florida deposits, and the southern facies is a graywaeke- 

 volcanic succession. The graywacke-volcanic facies is called the clastic- 

 volcanic facies by Wassail ( 1957 ) and the carbonate facies the limestone 

 and clastic-volcanic facies. North of the carbonate facies is the exaporite 

 facies. These facies hold for the Upper Jurassic and Lower and Upper 

 Cretaceous; the sites of deposition did not shift appreciably during the 

 entire time. The approximate facies zones are indicated on the geologic 

 map of Fig. 42.2. The San Cayetano formation consists of some 35,000 

 feet of highly folded shales, slates, phvllites, and minor amounts of schist 

 The Vinales limestone consists mainly of dark gray to black, fairly thin- 

 bedded limestone, but it includes considerable amounts of dark shale and 

 chert. Its thickness from place to place has been variously estimated from 

 1000 to 5000 feet. It crops out chiefly in parts of western Cuba. 



The lower Tertiaiy deposits are mostlv elastic and contain coarse eon-
