Story of Texas Limestone
4.5 Billion years ago
Dust and debris accretion accelerated the metamorphic rock mountain formation associated with large-scale movements of the Earth’s crust.
600 Million years ago
Pre-Cambrian era Texas was the floor of the Panthalassa superocean that surrounded the supercontinent Pangaea and the Gulf of Mexico was a mountain range. Tectonic plate shifts caused Texas to rise while the Gulf of Mexico began to sink.
300 Million years ago
The Pangaea land mass continued shifting and separating, and over time, Limestone composed of skeletal fragments and minerals, was deposited as a result of sea level fluctuations.
Present Day
Limestone is a hard, durable and easily accessible carbonate sedimentary rock. It’s a popular building material for cladding, paving and walls. Limestone is also an admixture for cement, mortar and asphalt concrete, as well as an ingredient used for soil conditioners and paint pigments.
