The fullerene (C60) is economically significant due to its significant applications in diverse areas like nanochemistry, superconductivity, materials science, etc. The carbon allotrope fullerene C60 and C70 are identified within the thick sequence of black carbonaceous units belonging to the shungite suite of rock at the baryte mine, Mangampet, Andhra Pradesh. Since this is the first of its kind from India's geological material, the exploration of fullerenes enriched barytes from the mines at Mangampet in the Kadapa district is essential. In the present study, remote sensing techniques such as hyperspectral analysis followed by Mixture Tuned Matched Filtering (MTMF) and Support Vector Machine (SVM), and Principal Component Analysis (PCA) were used for exploring the presence of fullerene bearing baryte deposits in the Mangampet mine. The spectra measured for baryte samples were used as reference spectra for deriving true endmember from Landsat OLI and ASTER satellite data. The detailed characterisation of structure and chemistry of the baryte samples were carried out using techniques like Energy Dispersive X-ray Fluorescence (EDXRF), X-ray Powder Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), and Fourier-Transform Infrared Spectroscopy (FTIR) techniques. The High-Performance Liquid Chromatography (HPLC) and Matrix-Assisted Laser Desorption/Ionization (MALDI) mass spectrometry analyses confirm fullerene presence in baryte deposits. The retention time at 11.783–11.822 min obtained from HPLC and high-intensity rate m/z at 720.178 obtained from MALDI spectra suggest fullerene in baryte mine deposits. The remote sensing exploration of fullerene bearing shungite suite of rocks in baryte mineral deposits of Mangampet mine has opened up new research areas for converting this material into value-added products.

“…It is the most widely adopted method to discriminate between different lithologies (Adiri et al, 2016;Si Mhamdi et al, 2017). The choice of bands is related to the spectral difference of the material with respect to its environment (Si Mhamdi et al, 2017;Thannoun, 2013).The application of the combinations of previous studies (Esamaldeen, 2012;Adiri et al, 2016;Si Mhamdi et al, 2017;Yousefi et al, 2018), did not allow for specification of the exact limit between these two lithological groups. For this reason, the present study adopted combinations according to the reflectance of the formations targeted, and it appears that the ratios (5/7, 3/2 & 4/5) and the ratios (3/1, 5/4 & 7/5) in RGB respectively are considered to be the best reports of bands, due to their ability to improve the spectral reflectance of lithology and linear structures (Figure 8).…”

El Jbel Tijekht es una de las estructuras geológicas más importantes de la cordillera de Ougnat-Ouzina en el Anti-Atlas Oriental. Este macizo en forma de media luna fue afectado por una red de fracturas que es visible a diferentes escalas. Es particularmente rico en vetas mineralizadas de barita y está asociado con otros minerales (por ejemplo, pirita, calcopirita, esfalerita y galena). Para estudiar los sistemas de fracturas en la zona minera de Jbel Tijekht, optamos por una combinación de teledetección e investigación de campo que se convirtió en una importante herramienta para la cartografía de las fracturas y la exploración de minerales. Este trabajo presenta un enfoque metodológico para detectar los lineamientos estructurales. Para ello, se aplicaron diversas técnicas a la imagen del Landsat 8 para mejorar la visibilidad de las estructuras lineales. Tras correcciones radiométricas y atmosféricas, los colores compuestos y los filtros direccionales aplicados al componente principal (PC1) se pudo establecer un mapa de lineamientos para Jbel Tijekht. La validación y corrección de estos lineamientos se basan en documentos preexistentes combinados con observaciones de campo. El análisis estadístico del mapa de lineamientos permite la identificación de al menos tres sistemas de fractura direccional con orientaciones promedio NS, NE-SW y ENE-WSW. Los sistemas NS y NE-SW muestran una alta densidad en la mayor parte del área de estudio. Estos resultados claramente se superponen a diferentes estructuras tectónicas y a las vetas existentes. Esto permitió establecer un vínculo geológico entre la litología, los sistemas de fracturas y la mineralización. La densidad de fracturas puede atribuirse a las últimas fases de fragilidad del orógeno varisco, lo que refleja la reología de las unidades de roca; la alta densidad de fractura se observa en las rocas competentes como las areniscas de Tabanit. Estas zonas constituyen un área favorable para los depósitos de mineralización.

“…At the Gua Musang Goldfield, China, Yao et al [145] applied ASTER SWIR and TIR data to map rock types and quartz content to search for promising host rocks for possible gold mineralization. Yousefi et al [146] integrated ASTER and Landsat data to map geologic setting of the Zarshuran Carlin-type deposit in Iran. ASTER data provided mineralogical and lithologic information, and Landsat provided regional structural information.…”

The Advanced Spaceborne Thermal Emission and Reflection Radiometer is one of five instruments operating on the National Aeronautics and Space Administration (NASA) Terra platform. Launched in 1999, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) has been acquiring optical data for 20 years. ASTER is a joint project between Japan’s Ministry of Economy, Trade and Industry; and U.S. National Aeronautics and Space Administration. Numerous reports of geologic mapping and mineral exploration applications of ASTER data attest to the unique capabilities of the instrument. Until 2000, Landsat was the instrument of choice to provide surface composition information. Its scanners had two broadband short wave infrared (SWIR) bands and a single thermal infrared band. A single SWIR band amalgamated all diagnostic absorption features in the 2–2.5 micron wavelength region into a single band, providing no information on mineral composition. Clays, carbonates, and sulfates could only be detected as a single group. The single thermal infrared (TIR) band provided no information on silicate composition (felsic vs. mafic igneous rocks; quartz content of sedimentary rocks). Since 2000, all of these mineralogical distinctions, and more, could be accomplished due to ASTER’s unique, high spatial resolution multispectral bands: six in the SWIR and five in the TIR. The data have sufficient information to provide good results using the simplest techniques, like band ratios, or more sophisticated analyses, like machine learning. A robust archive of images facilitated use of the data for global exploration and mapping.
