A Machine Learning Zircon Trace Element Tool to Predict Porphyry Deposit Type and Resource Size

open access: yesJournal of Geophysical Research: Machine Learning and Computation
Porphyry deposits are primarily known for their association with base metals like copper and to some extent molybdenum and gold. Here we present machine learning models, based on zircon composition, that provide quantitative distinction between different
