Sediments Lining West Coast of Yucatán Peninsula, Mexico – March 24th, 201118.5N 91.5W
This image shows the part of Yucatán Peninsula, in southeastern Mexico, along the Gulf of Mexico. The peninsula lies east of the Isthmus of Tehuantepec (lower left quadrant, where the land is narrowest).
The peninsula is the exposed portion of the larger Yucatán Platform, all of which is composed of carbonate and soluble rocks, mostly limestone. Here, sediments, probably carrying limestone, can be seen along the coast, particularly by the Términos Lagoon or Laguna de Términos (center).
