content: Lockport Dolomite Flint Chert is also known Ancaster or Goat Island. It is white, dark gray to bluish gray, commonly mottled with darker spots due to the accumulation of foreign matter such as clay, carbonaceous matter, limonite, etc. When heat-treated it becomes pink, purple, red, brown, or black. When weathered it becomes dirty white with reddish-brown discolorations from the weathering of the included pyrite. It has inclusions of xenolithic partially silicified dolomite, sponge spicules, and other fossils. It has a coarse to fine texture. Deposits include elongated nodules.
