Abstract
A study of two petroleum exploration wells in the southern part of Pinar del Río Province shows that the Neogene lithofacies complex can be divided into two subcomplexes. The first, in the Palacios basin, consists of 1,000 m of Aquitanian through Vindobonian carbonate and terrigenous clastic strata. The second subcomplex, outside of the Palacios basin, consists of 800 m of carbonate rocks, in which Aquitanian strata are absent and the post-Aquitanian Miocene overlies the Paleogene directly.
The Mariel-Carraguao fault, which is the eastern border of the Pinar del Río Miocene lithofacies complex, was active at least as early as Oligocene time.
