Summary:

"The Belt Basin displays one of the planet's best-exposed and best-preserved sequences of Mesoproterozoic sedimentary and igneous rocks. This volume focuses on research into this province; kindles ideas about this critical era of Earth evolution; and covers aspects of the basin from its paleontology, mineralogy, sedimentology, and stratigraphy to its magmatism, ore deposits, geophysics, and structural geology"-- Provided by publisher.

A collection of papers from the 5th Belt Symposium, Salmon, Idaho, 2013, on the geology of the Belt Basin, or Purcell Basin; the region is the Rocky Mountain Region of the northern United States, extending into Canada.
