| Abstract |
"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. |
