Summary:
Wood River Formation. Is lowermost of four regionally persistent anhydrite units identified below the Punta Gorda Anhydrite in the subsurface of the South Florida basin. Consists of basal coarse clastic rocks overlain by anhydrite and microcrystalline brown dolomite and minor micritic limestone. Thickness is 2,100 feet in type well. Overlies Jurassic (189 Ma) rhyolite porphyry; underlies Bone Island Formation (new). Age is Late Jurassic(?) based on the estimated time interval between rhyolite emplacement and deposition of the basal clastic rocks.
Type section (subsurface): depth-interval 16,510 to 18,610 ft, Bass Collier Company 12-2 well P-778, in sec. 12, T. 52 S., R. 27 E., Collier Co., FL. Named from Wood River, a creek 4 mi southeast of the type well.
