Mineral chemistry is transforming the way in which mining companies explore for mineral deposits via the utilization of vectoring and fertility studies. In the past, these methods have mostly been employed during exploration for porphyry Cu deposits due to the distinctive composition of the magmas involved and extensive alteration zones relative to other deposit types. For example, detrital zircon studies can assist with the identification of regions with oxidized intrusives of a particular age, while epidote and chlorite mineral chemistry from the propylitic alteration zone, often referred to as “green rocks”, can be used to evaluate the fertility of the system and calculate distances to the heat source.
Recent studies have also shown that mineral chemistry can be employed as an effective tool when exploring for other deposit types, such as IOCG, skarn and VHMS. In addition, it has been demonstrated that indirect proxies such as hyperspectral signatures could also be utilized to infer mineral chemistry. The integration of machine learning techniques has aided the classification and domaining of various datasets, including LA-ICP-MS imaging results.
However, a deeper understanding of the mechanisms that can affect the mineral chemistry remains a necessity. Previous studies have demonstrated that mineral chemistry is influenced by other mineral phases co-crystallising from the same magma or hydrothermal fluid. For example, zircon chemistry can be significantly affected by co-precipitating apatite and titanite, while epidote and chlorite chemistries are influenced by the presence of inclusions (rutile, titanite, etc.) and co-existing sulphides.
This Special Issue welcomes contributions focused on mineral chemistry from magmatic and hydrothermal minerals and its application in aiding the exploration for various deposit types. Studies on improvements of previously published proxies and novel approaches are also welcome.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Minerals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
