Special Issue Information

Dear Colleagues,

In many environments where traditional field surveys are difficult and time-consuming, remote sensing technology enables quick delineation of mineralized zones over wide areas at minimum cost and effort. Minerals and rocks are identified based on their mineral absorption properties present in the visible, near-infrared (VNIR), shortwave infrared (SWIR) (0.4–2.5 μm), and thermal infrared (TIR) (8-12 μm) wavelength regions. Iron oxides and hydroxides are characterized in the spectra region of the VNIR (0.4 to 1.1 µm) region, whereas the SWIR absorption features (2.0 to 2.5 µm) distinguish the spectra of carbonates, clay minerals, and sulphates. TIR distinguishes the spectra of silicates. Multispectral and hyperspectral remote sensing data are used for mineral exploration in various environments to delineate structural elements that may have controlled mineralization as well as alteration zones. Mineral exploration in these environments is examined using numerous image processing techniques, such as minimum noise fraction (MNF), principal component analysis (PCA), band ratio (BR), matched filtering (MF), machine learning, and image classification.

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 2000 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.

Porphyry copper ore is a vital strategic mineral resource. It is often associated with significant hydrothermal alteration, which alters the original mineralogical properties of the rock. Extracting alteration information from remote sensing data is crucial for porphyry copper exploration. However, the current method of extracting hydrothermal alteration information from ASTER remote sensing data does not consider the influence of disturbing factors, such as topography, and ignores the weak report of surface minerals, which has significant limitations. Therefore, this paper selects the Gondwana region of the East Tethys–Himalayan tectonic domain as the study area, combines waveform calculation with principal component analysis methods, proposes a spectral feature-enhanced principal component analysis (EPCA) method, and constructs a model to complete the automatic selection of principal components for each scene image. The results show that the etching information extracted by the EPCA method is significantly better than the traditional Crosta method in terms of etching area and spatial aggregation and discovers several prospective mineralization areas that have not yet been explored and exploited, such as Sakya and Xietongmen counties in Rikaze, providing theoretical support for subsequent mineralization exploration and large-scale mineral extraction. Meanwhile, obtaining the alteration information of the whole area can help to understand the distribution of mineralizing elements from a macroscopic perspective in the future, which is of great scientific significance in order to deeply analyze the formation process of metal deposits in mineralizing areas and improve the theory of porphyry mineralization.
