Surficial Geology of Florida

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN STYLE="font-weight:bold;"><SPAN>This product depicts the statewide geologic map of Florida. The data provided are to be used as a resource for general mapping products. Much of Florida is covered by Pliocene to Holocene undifferentiated siliciclastics that range in thickness from less than one foot to greater than 100 feet. In an effort to make this map more useful, geologists identified the first recognizable lithostratigraphic unit occurring within 20 feet (6.1 meters) of the land surface. In areas where highly karstic limestone underlies the undifferentiated siliciclastics, paleosinkholes may be infilled with significantly thicker sequences of siliciclastics. If the shallowest occurrences of the karstic limestone is 20 feet (6.1 meters) or less below land surface, the limestone formation was mapped. If the limestone is more than 20 feet (6.1 meters) below land surface, an undifferentiated siliciclastic unit was mapped.</SPAN></SPAN></P></DIV></DIV></DIV>
