Lantern Hill - Geology

Geology

The hill is composed mostly of high-purity milky quartz and it occupies the inactive Lantern Hill Fault, which runs south into the Atlantic Ocean. Analysis of the quartz reveals that it is 238 million years old—the mid-Triassic Period of the Mesozoic Era in geologic time. The formation of the fault and the quartz are associated with the early formation of the Atlantic Ocean (Altamura 1995; Altamura 2003).
