The Central Atlantic magmatic province (CAMP) is the Earth's largest continental large igneous province, covering an area of roughly 11 million km 2. It is composed mainly of basalt that formed before Pangaea broke up in the Mesozoic Era, near the end of the Triassic and the beginning of the Jurassic periods.
Jun. 21—Making maps, hiking, exploring the geology around them and making a seismometer are among the things kids in University of Texas Permian Basin's Geology Camp have learned about this week.
Old Rag Mountain is underlain by Old Rag Granite, named for its ubiquitous exposure on the mountain, formed during the Grenville Orogeny about a billion years ago. About 400 million years after the Grenville orogeny during the Catoctin Formation, deposition of basaltic magma occurred during the formation of the Iapetus Ocean, forming a layer of greenstone over the granite.
The geology of Smith Rocks is volcanic. It is made up of layers of recent basalt flows overlaying older Clarno ash and tuff formations. Approximately 30 million years ago, a large caldera was formed (Crooked River caldera) when overlying rock collapsed into an underground magma chamber. This created a huge amount of rock and ash debris that ...
After earning his doctorate, Branson taught at Oberlin College in Ohio for five years. He joined the Geology department at the University of Missouri in 1910. During his doctoral studies, he had spent time searching for fossils near Lander, Wyoming and so he determined to set up a camp for the hands-on study of geology and paleontology nearby.

The CMC climbs good rock and is essentially free of snow and ice. It also has the advantage of a good camp high on the flank of the mountain. [5] The Direct South Buttress, a grade IV claim rated from 5.7 A3 to 5.9 C1, is a technical route suited for aid and Alpine climbing.
David Kear's 'Geology of Ironsand Resources of New Zealand' (NZ Dept of Scientific & Industrial Research 1979) says, "The ironsand deposits extend from south Kaipara and Muriwai, north of Auckland, for over 300 miles southwards to the Whangaehu River, south of Wanganui". Soluble iron in concentrates exceeds 50% in most locations.
