Geology of the Antarctic Peninsula Peninsula started to take on its modern shape. Roughly 220 million years ago, the continents of Antarctica, South America, and Africa rifted apart. This rifting created low relief basins which allowed for the transport of sediments and subsequent deposition of sedimentary rocks, which happen to be the oldest on the peninsula. These rocks belong to the Trinity Peninsula Group (TPG), which are mostly composed of siliciclastic turbidite deposits, ~1200–3000 m thick, deposited in a marginal marine basin. Unfortunately their age is poorly constrained, but they are most likely from the upper Permian and Triassic. The clastic component of these sediments
