Graphite Peak Explained

Graphite Peak (-85.05°N 217°W) is a peak, high, standing at the northeast end of a ridge running 3nmi northeast from Mount Clarke, just south of the head of Falkenhof Glacier in Antarctica. It was so named by the New Zealand Geological Survey Antarctic Expedition (1961–62) because of the graphite found on the peak.^[1]

Paleontology

Fossiliferous sedimentary rocks containing the Permian–Triassic boundary outcrop on the slopes of Graphite Peak. These sedimentary strata contain well-preserved plant, invertebrate, and vertebrate fossils that are important in understanding paleoclimatic and paleontologic changes associated with the Permian–Triassic extinction event. Graphite Peak is the location where the first fossil of an Early Triassic tetrapod was discovered in Antarctica.^{[2] [3] [4] [5]}
