What type of rock is found in Vermont?

Vermont is known for its Green Mountains, which are composed primarily of two types of rock: granite and marble. Granite is an igneous rock that is formed from the cooling of magma beneath the Earth's surface. It is typically composed of feldspar, quartz, and mica. Marble is a metamorphic rock that is formed when limestone undergoes heat and pressure beneath the Earth's surface. It is typically composed of calcite and other minerals.
