Zircon oxygen isotopic constraints from plutonic rocks on the magmatic and crustal evolution of the northern Appalachians in southern New England, USA
Oxygen isotopes are a valuable tool for determining the role of supracrustal rocks in the genesis of magmas and help constrain the source regions of plutonism in the northern Appalachian mountains of North America. Zircons from 35 igneous or metaigneous rocks mainly from southern New England, USA, were analyzed for 18O/16O to locate and investigate the origin of anomalous δ18O magmas and to evaluate the regional meteoric water-rock interaction. δ18O values of the zircons obtained using the...[Show more]
