Hyperspectral remote-sensing in the reflected infrared and thermal infrared regions offers a unique and efficient alternative for mineral mapping, as most minerals exhibit spectral features in these regions, mainly in the shortwave and longwave infrared. Airborne hyperspectral data in both spectral regions, acquired with the AisaFENIX and AisaOWL (Specim) sensors over Makhtesh Ramon in Israel, ...

Abstract In this study, we present the application of two novel hybrid multiple-criteria decision-making (MCDM) techniques in mineral potential mapping (MPM), namely FUCOM-MOORA and FUCOM-MOOSRA, as robust computational frameworks for MPM. These were applied to a set exploration targeting criteria skarn. The multi-objective optimization method on basis ratio analysis (MOORA) simple (MOOSRA) app...

Most geoscientists are familiar with the colorful LandSat imagery we have been provided with for almost 30 years. These multispectral data sets have allowed us to see the earth in colors not accessible to the human eye and hence allowed discrimination of previous, not distinguishable geological features. Technology has progressed and it is now possible to view the earth not only in a few, but h...

Variation in the mineral composition of rocks results in a change of their spectral response capable of being studied by imaging spectroscopy. This paper proposes the use of a low-cost handy sensor, a calibrated visible-very near infrared (VIS-VNIR) multispectral camera for the recognition of different geological formations. The spectral data was recorded by a Tetracam Mini-MCA-6 camera mounted...

The Carajás Mineral Province is located in the eastern portion of the Amazon craton, state of Pará and contains a significant number of mineral deposits, most of them exhibiting structural and lithological controls, such as sets of dilation faults. This paper presents the results of the interpretation of simulated MAPSAR (MultiApplication Purpose SAR) data, integrated with aerogeophysical data,...

The mineral ore potential of many mountainous regions of the world, like the Kurdistan region of Iraq, remains unexplored. For logistical and sometimes political reasons, these areas are difficult to map using traditional methods. We highlight the improvement in remote sensing geological mapping that arises from the integration of geomorphic features in classifications. The Mawat Ophiolite Comp...

Over the last two decades, the California Geological Survey (CGS) has increasingly received requests for environmental geology/mineralogy/geochemistry information from State and local agencies, consultants, industries, and the public. These requests have led to projects to identify and map potential mineral hazards such as naturally occurring asbestos, heavy metals, and radon. In these projects...

The southern part of Skull Valley has potential for shallowly buried mineral deposits. The most likely deposit type is either skarn/porphyry copper deposits, perhaps with surrounding polymetallic lead-zinc-silver replacement deposits or "distal disseminated" gold-silver deposits. The area (1) is structurally complex with both thrust and high-angle faults, (2) contains lithologic units favorable...
