Brief description Hydromagmatic amphibole in some Precambrian (>600 million years old) komatiites and other ultramafic rocks in Australia, Canada and Russia indicates >3% water in the parental magmas. This magmatic water could be crustal or mantle in origin. Constraints on the water source would profoundly impact concepts of Precambrian crustal evolution and water recycling. The ultimate goal of this project is to provide constraints on the role of water in early Earth magmatism, through in situ microbeam and nanobeam analysis of the amphibole to produce an integrated trace element and isotopic dataset for geologically and chemically diverse types of Precambrian ultramafic rocks.
