What type of rock is Eagle Ford Shale?
The Eagle Ford shale is a hydrocarbon-bearing, Late Cretaceous formation that was deposited in a marine continental shelf environment. The Eagle Ford formation consists of organic-rich calcareous- mudrock with mineralogy ranging from 40-90% carbonate minerals, 15-30% clay, and 15-20% silica (quartz).
