Google Map of Geology



This documentary, in the form of a Google Map, provides examples of geology terminology throughout the world that you can zoom in close on to see where the depressions, eduction, eskers, fabric, folds, faults, joints, horses, hoodoos, intrusions, kettles, lava fields, melange, monadnocks, polje, rifts, roof pendants, stratum, talus  actually are. The map legend contains Wikipedia descriptions of various geological terminology that are color and symbol coded to examples of each term. In addition, this map contains a Google Earth KML file that enables you to examine each site in 3D. The intent is to improve your understanding of geology by enabling you to experience it by taking you to the actual site of the geology examples presented.
 

#18 - Roof pendant

Wikipedia: In structural geology, a roof pendant, which also known as a pendant, is a mass of country rock that projects downward into and is entirely surrounded by an igneous intrusion such as a batholith or other pluton. A roof pendant is an erosional remnant that was created by the removal by erosion of the overlying country rock that formed the roof of the igneous intrusion that encloses it. If this downward protruding mass of roof rock still has a connection to the main, surrounding mass of country rock, they are known by structural geologists as either septa or screens.[1][2][3] Roof pendants typically have been strongly metamorphosed through the processes of contact metamorphism.[4]
