Guam's Point Udall is the westernmost point of the U.S., as measured from the geographic center of the United States. [36] [37] The Mariana chain, of which Guam is a part, was created by collision of the Pacific and Philippine Sea tectonic plates. Guam is located on the micro Mariana Plate between the two.
Geologic map of Guam. The geology of Guam formed as a result of mafic, felsic and intermediate composition volcanic rocks erupting below the ocean, building up the base of the island in the Eocene, between 33.9 and 56 million years ago. The island emerged above the water in the Eocene, although the volcanic crater collapsed.
The north of Guam is a result of this base being covered with layers of coral reef, turning into limestone, and then being thrust by tectonic activity to create a plateau. The rugged south of the island is a result of more recent volcanic activity. Cocos Island off the southern tip of Guam is the largest of the many small islets along the ...
