The up to 15 million year old Sandwich plate has a regular formation of about 6-7 cm per year, caused by seafloor spreading at the East Scotia Ridge, while in its east the plate is eroding due to subduction of the Southamerican plate beneath the Sandwich plate. The southern limitation of the Sandwich plate is caused by a transformation fault along the Antarctic Plate.

The island arc of the South Sandwich Islands forms the highest volcanic elevations on the Sandwich Microplate. Highest mountain with 1,370 m above sea level is Mount Belinda Volcano on Montagu Island. The young Sandwich Microplate is bordered in the East by the over 8,000 m deep abyssal trench, and in the West by the East Scotia spreading zone which consists of 10 well defined segments.
