Exploring covered terrains is a challenge that requires the integration of multiple sources knowledge, particularly in initial stages mineral exploration. The Apuí region, located Southwestern Amazon Craton, has small and constant gold production, despite deep cover limited geological knowledge. mainly hosted quartz veins breccias cut Paleoproterozoic volcano-sedimentary sequences. occurrences ...

Machine learning methods that have been used in data-driven predictive modeling of mineral prospectivity (e.g., artificial neural networks) invariably require large number of training prospect/locations and are unable to handle missing values in certain evidential data. The Random Forests (RF) algorithm, which is a machine learning method, has recently been applied to data-driven predictive map...

This paper describes the application of a well-known Multi Criteria Decision Making (MCDM) technique called Preference Ranking Organization METHod for Enrichment Evaluation (PROMETHEE II) to explore porphyry copper deposits. Various raster-based evidential layers involving geological, geophysical, and geochemical geo-datasets are integrated to prepare a mineral prospectivity mapping (MPM). In a...

the investigated area is located 30 km south of sabzevar in halakabad village. geological phenomenons in area follow a trend of nw-se. mineralization consists of metallic and non-metallic (kaolin) mineralization. disseminated and veinlet mineralization is generally associated with argillic alteration type. pyrite is the most widespread type of sulfide mineralization in halakabad occurrences. it...

Discrimination of the blind and dispersed mineralization deposits is a challenging problem in geochemical exploration. The frequency domain (FD) of the surface geochemical data can solve this important issue. This new exploratory information can be achieved using the interpretation of FD of geochemical data, which is impossible in spatial domain. In this research work, FD of the surface geochem...

Several large-scale porphyry copper deposits (PCDs) with high economic value have been excavated in the Duolong ore district, Tibet, China. However, altitudes and harsh conditions this area make traditional exploration difficult. Hydrothermal alteration minerals related to PCDs diagnostic spectral absorption features visible–near-infrared–shortwave-infrared ranges can be effectively identified ...

The Chah-Shaljami polymetal ore deposit contains heavy metal anomalies in various mineralization zones. Geochemical distribution and correlation of elements in surficial soilsindicate that sulfide, sulfate, sulfosalt and silicate mineral occurrences (e.g. Pyrite, chalcopyrite, galena, sphalerite, molybdenite, enargite, hornblend and biotite) in mineralization and stockwork zones resulted in the...

The study area, located in the southern section of the Central Iranian volcano–sedimentary complex, contains a large number of mineral deposits and occurrences which is currently facing a shortage of resources. Therefore, the prospecting potential areas in the deeper and peripheral spaces has become a high priority in this region. Different direct and indirect methods try to predict promising a...
