The Lawrence Formation, also referred to as Lawrence Shale, is a Late-Carboniferous geologic formation in Kansas, extending into Nebraska, Iowa, Missouri, and Oklahoma. [2] [1] This unit was named by Erasmus Haworth in 1894, the year that Haworth founded the Kansas Geological Survey in Lawrence, Kansas, having personally surveyed the formation the year before. [2]
