TitleMarble, Adirondack Mountains, New York
DescriptionThis 10 cm wide marble sample is from the Adirondack lowlands in upstate New York. It is nearly 100% calcite, but close examination reveals a few brown flakes of phlogopite and some silvery specks of graphite. Some marbles contain conspicuous metamorphic minerals. This one does not because it formed from metamorphism of a limestone that contained little but calcite, so the chemical components needed to form new metamorphic minerals were not present.
