Although Alpine peridotites are relatively common in collisional orogenic zones, garnet‐bearing peridotites are rare and only associated with high pressure/ultra‐high pressure or temperature (HP/UHP or T) terranes [ Brueckner and Medaris , 2000; Medaris , 1999]. Until recently all reported occurrences of Alpine‐type garnet peridotites and HP/UHP terranes were in Eurasia and Africa, with one occurrence in the Seward Peninsula, Alaska [ Till , 1981; Lieberman and Till , 1987]. Now a new Alpine‐type garnet peridotite locality has been discovered in the Caribbean island of Hispaniola. This discovery is the second of its kind in the Americas.
