Zusammenfassung: | Lithologic characteristics of Miocene sediments exposed in the Devil's Mill Hopper, a large sink hole located in north-central peninsular Florida, are briefly discussed. These features include silicified clay, the gradation of clay into lenses and irregular masses of limestone and sandstone, the possible dolomitization of clay, intraformational breccias and conglomerates, and a probable phosphate reaction zone that appears to represent hard-rock type phosphate in the process of being formed. |
