Excerpt from Contributions to the Geology of Mineral Deposits: A. Exploration for Porphyry Metal Deposits Based on Rutile Distribution, a Test in Sumatera; B. Titanium Mineral Resources of the United States, Definitions and Documentation

At the Tangse porphyry-copper prospect, rutile in thick soil reflects the distribution of the quartz-sericite and biotite-chlorite zones of hydrothermal alteration at depth. Detection of rutile in the samples is not simple, but studies of rutile distribution may nevertheless be a cheap exploration method for tropical porphyries.
