Whole-rock major, trace elements, and Sm-Nd isotopic analysis of mafic and ultramafic rocks from Matthews Ridge, NW Guyana, South America v.2
Abstract
This updated data includes an additional sample from a regional suite of mafic and ultramafic rocks in the Matthews Ridge (MR) region of NW Guyana, Guiana Shield, South America. The focus of this data is geochronology and geochemistry studies to characterize the number of distinct magmatic suites, and for each, their ages, mantle sources, and differentiation histories.
