Superior, Arizona. The main goal of FAMOS is to enhance our understanding of the crustal-scale magmatic processes that lead to the formation of economic porphyry-type ore deposits.

The Embalse de Yeso allows us to study the relationship between intrusive igneous rocks (whitish on the right shore) and the thick volcanic deposits (opposite shore) preceding economic ore formation.

Cerro del Medio. The central Chilean Andes allow us to investigate not only the magmatism that formedlarge copper deposits but also the preceding magma evolution that resulted in the deposition of the volcanic rocks that are so characteristic for the Andes.

Morenci, Arizona. Metals are essential for society’s transition to a carbon-neutral future. The FAMOS consortium wants to deliver techniques to make exploration more efficient, minimising environmental and ecological impacts.

First ideas and results from FAMOS were tested by Co-I Robin Armstrong and colleagues from AIMC in the Ordubad region, Nakchivan, Azerbaijan, to constrain the potential for copper deposits in the district.

Ray, Arizona. Finding new deposits of copper, an essential component in 'green' technologies, has become more difficult. FAMOS aims to identify districts along active and ancient magmatic arcs that could host economic copper mineralisation.

The olivine crystals were studied by FAMOS lab technician Barbara Kunz in order to choose crystals with melt inclusions for further sample preparation and analysis.

Co-I Andrew Miles and PhD student George Stonadge carried out fieldwork in the Philippines to collect samples for FAMOS from the Pinatubo volcano and nearby porphyry deposits.

The Sella Bassa mine in the Ivrea zone allows the sampling of sulfide-rich, lower crustal cumulates. These are made up of amphibole-pyroxene-olivine cumulates with Ni and Cu sulfides.

The Ivrea zone is an almost unique exposure of an entire mantle to upper crustal section of lithosphere, making it a superb natural laboratory for studying some of the more cryptic processes that happen in the lower crust.

Project summary

Focus: To develop new exploration tools for mineral resouces by understanding the processes by which metals are concentrated in magmatic arcs.
Funding: NERC
Start date: 1 May 2017
End date: 31 December 2022

We are working with industrial and academic partners to develop new exploration tools that will help locate metal resources in volcanic arcs by understanding the fundamental processes involved in cycling magmas, fluids and metals in these zones.

Why do we need to look for new ore deposits?

Society is dependent on a reliable supply of metals and minerals for economic growth, improved standards of living, and development of infrastructure.

Discovering new ore deposits is increasingly difficult because most of the ores exposed at the Earth’s surface have already been found. Mineral exploration companies increasingly have to search for hidden deposits, concealed beneath up to a kilometre of barren rock.

New concepts, approaches and tools are required for the location and extraction of ores, with minimal environmental impact and financial risk to investors.

A new approach

The search for new ore deposits has to consider the 'ingredients', the processes and environments that favour their formation. Historically, most research has focused on the 'trap' in the Earth's shallow crust where the ore minerals are finally deposited.

The FAMOS project will focus deep in the Earth's crust, to probe the formation and evolution of the molten rocks (or magmas) that are ultimately responsible for some of the largest accumulations of metals on the planet. See the project approach page for more details.

Bridging the divide

The project combines a desire to understand fundamental processes about our planet works - how metals, magmas and fluids are cycled through subduction zones - withdelivering outcomes that will benefit industry through improved exploration tools.

The project bridges the divide between academic and applied research in a way that is not normally possible through projects funded entirely by industry or entirely by government agencies. This bridging activity lies at the heart of the Natural Environment Research Council’s (NERC) highlight topic funding scheme.

The team

A multidisciplinary team of researchers has been assembled from the fields of economic geology, igneous and metamorphic petrology, volcanology, geochemistry, numerical modelling and fluid dynamics.

The project also has a diverse group of international scientific collaborators and the support of several of the world’s largest mineral exploration companies.

We are using a wealth of modern analytical tools from nine universities and research institutes around the UK that enable most of the elements in the periodic table to be measured.
