The Kioto limestone, extends from the lower the middle Jurassic with a thickness 2,000 feet (610 m) to 3,000 feet (914 m). The upper Jurassic is represented by the Spiti black shales, and stretches from the Karakoram to Sikkim the Great Limestone in northern England. they are not same
I am asking about this.
They just named it great limestone due to its vast extension. Locally they called it as great limestone. Earlier they were thinking it as the age of kioto as no such evidence found. later some evidence of kaghan valley is matched to it.
