Analytical Protocol for U-Th-Pb Chemical Dating of Monazite using CAMECA SXFive EPMA Installed at the Mantle Petrology Laboratory, Department of Geology, Banaras Hindu University, Varanasi, India

Journal of the Geological Society of India, 2019
Abstract Chemical Th-U-total Pb method of dating monazite by an Electron Probe Micro Analyzer (EPMA) is a well-known technique for constraining chronology of geological events. In this communication, the analytical conditions of monazite dating using SXFive EPMA recently installed at the Department of Geology, Banaras Hindu University is

Geology, Mineral Chemistry, and Structure of the Kimberlites at Diavik Diamond Mine: Indicators of Cluster-Scale Cross-Fertilization, Mantle Provenance, and Pipe Morphology

2018
Abstract The Diavik diamond mine includes four diamondiferous kimberlite pipes (A154N, A154S, A418, and A21) and minor kimberlite dikes that are mined by Rio Tinto and Dominion Diamond Corporation. Pipe morphologies from A154S, A154N, and A418 show similar circular near-surface expressions, with expansion of cross-sectional area and ...
