Quantitative determination of the mineralogical composition of hydrothermally altered rocks was performed by means of the Rietveld method using X-ray powder-diffraction data. Initially, experiments were carried out to minimize systematic errors arising from preferred orientation of particles as well as micro-absorption. The precision of the proposed method was tested by independent replicate sa...

Bee keeping is indispensable to global food production. It is an alternate income source, especially in rural underdeveloped African settlements, and an important forest conservation incentive. However, dwindling honeybee colonies around the world are attributed to pests and diseases whose spatial distribution and influences are not well established. In this study, we used remotely sensed data ...

introduction the mahour exploration area is a polymetallic system containing copper, zinc and silver. the mineralization can be seen in two forms of veins and disseminations. this area is structurally within the lut block, west of deh-salm village. recent exploration work and studies carried out by geologists on this volcanic-plutonic area of lut demonstate its importance indicating new reserve...

Identification and mapping of the significant alterations are the main objectives of the exploration geochemical surveys. The field study is time-consuming and costly to produce the classified maps. Therefore, the processing of remotely sensed data, which provide timely and multi-band (multi-layer) data, can be substituted for the field study. In this study, the ASTER imagery is used for altera...

different types of iron oxides deposits have been identified along the khaf – dorouneh volcanic and plutonic belt in north east of iran. kuh-e-zar is one of these ore deposits known as fe- oxide gold deposit. the main purpose of this paper is to detect and discriminate the iron oxide minerals in this area based on the etm+ data. data processing has been done by envi (environment for visualizing...

The aim of this study is to carry out hydrothermal alteration mapping and structural using ASTER images in order identify indices that could guide mining exploration work the Poli area its surroundings. To achieve this, were first preprocessed correct atmospheric effects remove vegetation influence. Secondly, a lineament was conducted by applying Discrete Wavelet Transform (DWT) algorithms Firs...
