This book reviews the geochemical and petrological characteristics of potassic igneous rock
complexes and investigates the various tectonic settings in which these rocks occur. The
authors provide an overview and classification of these rocks and elucidate the geochemical
differences between barren and mineralized potassic igneous complexes. High-K rocks are
genetically associated with a number of epithermal gold and porphyry copper-gold deposits. In
recent years there has also been growing recognition of an association of such rocks with
iron-oxide copper-gold (IOCG) deposits intrusion-related gold deposits (IRGDs) and Carlin-type
gold deposits.This fifth updated and expanded edition incorporates new data and references from
world-class copper and gold deposits worldwide. It also includes the latest publications on the
petrogenesis of high-K magmatism and related mineral deposits. Numerous new representative ore
photographs of the mineral deposits described are also included in the new edition. As such
the book offers a valuable guide not only for academic petrologists working on alkaline rocks
but also for exploration geologists prospecting for epithermal gold and or porphyry copper-gold
deposits in modern and ancient terrains.
