Coppermine Peninsula is the 1.7 km long, 500 m wide and rising to 105 m rugged rocky promontory forming the northwest extremity of Alfatar Peninsula and Robert Island in the South Shetland Islands, Antarctica and lying between English Strait to the west and Carlota Cove to the east. It is linked to Alfatar Peninsula to the southeast by a narrow isthmus bounded by Carlota Cove to the north and the 1 km wide and 460 m indenting "Coppermine Cove" () to the south.

basalts hence given the location of the flood basalt sequence. With an area of and a volume of , the Coppermine River flood basalt sequence is larger than the Columbia River Basalt Group in the United States and comparable in size to the Deccan Traps in west-central India. This makes the Coppermine River flood basalts one of the largest flood basalt events ever to appear on the North American continent, as well as on Earth. The maximum thickness of the Coppermine River flood basalts is and consist of 150 lava flows, each
