Although this book is mainly about potassic igneous rocks and hydrothermal gold and gold-copper mineralization in volcanic arc environments, there is increasing evidence for the genetic association between volatile-rich potassic igneous rocks and iron-oxide-Cu-Au (IOCG) deposits (e.g. Campbell et al. 1998; Groves et al. 2010; Haywood …

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. …

Quartz is classically aligned with gold. The majority of hard rock deposits found appear to occur in quartz, and gold-in-quartz has even taken on a life of its own. The gold that appears in quartz is almost universally native, meaning that it's in a metallic formcontained in the crystalline quartz. …

The U–Pb system is considered the most robust and useful geochronometer for igneous rocks largely because of the mineral zircon (ZrSiO 4, Figure 1, and Cross-reference Uranium–Lead, Zircon), which contains high trace levels of U and strongly rejects Pb during crystallization. Therefore, present-day Pb within it is dominantly …

Modern potassic igneous rocks occur in a wide range of tectonic settings, from continental to oceanic and within-plate, some of which are not apparently associated with subduction (Joplin 1968; Morrison 1980; Muller et al. 1992b). It is therefore important, whether improving exploration models for ancient mineral deposits, or reconstructing ancient …

1. Introduction. Gold deposits are known in many thrust-fold areas, most of which are typical Late Precambrian and Phanerozoic mobile belts hosting "orogenic-gold" type of deposits (cf. Bierlein et al., 2001; Goldfarb et al., 2001).The formation of orogenic-gold deposits has been associated with syn-collisional or anorogenic granitoid …

2. Igneous Rocks. The rocks are primarily metal-bearing ornamental rocks. In some cases, gold particles in the rocks are visible to the eye. The cooling of molten rocks leads to the formation of igneous rocks. Magma and lava ( released during volcanic eruptions) cool, forming igneous rocks. The texture of the rocks can be: Aphanitic, fine-grained.

Although this book is mainly about potassic igneous rocks and hydrothermal gold and gold–copper mineralization in volcanic arc environments, there is increasing evidence for the genetic association between volatile-rich potassic igneous rocks and iron-oxide-Cu–Au (IOCG) deposits (e.g. Campbell et al. 1998; Groves et al. …

Igneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the molten rock solidifies.Intrusive Igneous …

Many epithermal gold and porphyry copper-gold deposits are hosted by high-K rocks. Therefore, this book is not only relevant to the academic petrologists working on alkaline rocks, but also to the exploration geologists prospecting for epithermal gold and/or porphyry copper-gold deposits in modern and ancient terranes.

Skarns: Skarns are contact metamorphic rocks that can be associated with gold deposits. They are typically formed in the contact zone between intrusive igneous rocks and carbonate-rich rocks, and can contain various minerals, including gold-associated minerals such as pyrite, chalcopyrite, and others.
