The first scientific reports of Alabama's geology were made during field studies by R. T. Brumby in the late 1830s and Sir Charles Lyell in the early 1840s. Michael Tuomey , appointed state geologist in 1847, completed a Geological Map of Alabama and in 1849 and published the first of two comprehensive reports on the state's resources a year later.
He began his official surveys of the state's mineral resources, beginning with Red Mountain and Jones Valley in central Alabama, the next summer. His Geological Map of Alabama was printed in 1849 and his First Biennial Report of the Geology of Alabama was published by M. D. J. Slade in 1850. [3] His report stated that:

The Ripley Formation is a geological formation in North America found in the U.S. states of Alabama, Georgia, Mississippi, Missouri, [1] and Tennessee. The lithology is consistent throughout the layer. It consists mainly of glauconitic sandstone. It was formed by sediments deposited during the Maastrichtian stage of the Late Cretaceous.
