The geology of Cuba has been a challenge to geologists because of features such as the presence of well-preserved [[Jurassic]] [[ammonite]]s, the rich [[Tertiary]] [[foraminiferal]] faunas (including remarkable [[Paleogene]] [[orbitoid]]s), the gigantic Upper [[Cretaceous]] [[rudistid]]s, the spectacular limestone Mogotes of Pinar del Rio, the extensive [http://www.merriam-webster.com/dictionary/outcrop outcrops] of [https://wwwf.imperial.ac.uk/earthscienceandengineering/rocklibrary/viewglossrecord.php?gID=00000000012 ultrabasic] [[Igneous rock|igneous]] rocks, the [[chromite]] and [[manganese]] deposits, and the extraordinary structural complexity. In addition to these features, the numerous petroleum seeps, many of them coming out of [[Wikipedia:Basic_rock|basic]] igneous rock, have attracted much attention.
