VOLCANO-PETROLOGY NEGLECTING GEOLOGY AND LOGIC

Geology, Petrology and Geochemistry of Traveler Rhyolite and Katahdin Pluton (northcentral Maine)

The Traveler Rhyolite-Katahdin Pluton Igneous Complex of of the Lower Devonian age in Northcentral Maine consists of two penecontemporaneous but genetically independent magmatic episodes. The earlier, voluminous episode includes the Traveler Rhyolite and the Katahdin Granite, whereas the slightly younger episode is comprised of minor intrusions of Horserace Quartz Diorite, Harrington Lake Porph...

Geology, geochemistry and earthquake history of Lō"ihi Seamount, Hawai"i’s youngest volcano

A half-century of investigations are summarized here on the youngest Hawaiian volcano, Lō"ihi Seamount. It was discovered in 1952 following an earthquake swarm. Surveying in 1954 determined it has an elongate shape, which is the meaning of its Hawaiian name. Lō"ihi was mostly forgotten until two earthquake swarms in the 1970s led to a dredging expedition in 1978, which recovered young lavas. Th...
