Bluestone
» View Bluestone Projects
Bluestone is a high quality product due to its silica content, compact nature and fine grains. It is used for patios, architectural facings, fireplaces, sills, sidewalks, and other features as well as a basic building material for churches, institutions, homes and businesses. Bluestone from Pennsylvania and New York is commercially known as Pennsylvania bluestone. These are a group of sandstones defined as feldspathic greywacke. The sand-sized grains from which bluestone is constituted were deposited in the "Catskill Delta" during the Middle to Upper Devonian Period of the Paleozoic Era, approximately 370 to 345 million years ago. If the initial deposit was made under slow moving water the ripples of the water action on the sand or mud will be revealed. This deposition process may be seen today at any ocean beach in shallow water or in a stream bed where conditions allow it to be observed. The term "bluestone" is derived from a deep-blue-colored sandstone first found in Ulster County.
