The Geology of Sebago Lake State Park - DigitalMaine
Dikes, sheet-like intrusions of igneous rock, were emplaced into the Sebago granite during the Mesozoic Era (225 to 65 million years ago) and can be seen in the rocks at both ends of Witch Cove beach. These dikes are narrow, dark colored rocks that cut across the lighter colored granite. No known faults affect the area (Osberg and others, 1985).

More rapid movement can be expected through coarse-textured materials such as sand or gravel than through fine-textured materials like silt and clay. The physical and chemical composition of the geologic material is equally important. Fine-grained materials present the most favorable environment for potential retardation.

Where Does Marble Come From? - Limestone
Marble is a metamorphic rock, which places it into a family of stones created by undergoing change, or metamorphosis. This natural stone is created when limestone (or less commonly, dolomite) is subjected to extreme heat and pressure near sites of igneous granite. This metamorphism causes recrystallization of the carbon-based minerals in the ...
