ZIRCON AS A PROXY FOR "TAKING THE TEMPERATURE" OF GRANITES: AN EXAMPLE USING ZIRCON THERMOMETRY APPLIED TO GRENVILLIAN MID-CRUSTAL MAGMAS IN THE BLUE RIDGE PROVINCE, VIRGINIA
The Grenville orogeny was a protracted (~200 m.y.) series of “hot” magmatic- metamorphic events that contributed to the growth of the Laurentian margin in the late Mesoproterozoic. The granites contain remarkably high Zr content, lack xenocrysts, and become zircon saturated at high temperatures, whi...
