Volume 1, Issue 1 , August 2023, , Pages 1-20

  Rock outcrops are generally covered by vegetation and the Quaternary deposits, so their enhancement on the satellite imagery can be impeded, and the identification of pixels of rock outcrops be a challenging task for field sampling in lithogeochemical surveys. Therefore, in order to map outcrops of different ...  Read More

Volume 1, Issue 1 , August 2023, , Pages 38-55

  The main objective of this research is to discriminate secondary iron minerals and investigate changes caused by their relocation during mining activities using multispectral satellite data collected over an 11-year period. To achieve this aim, MF and CEM performed using USGS library spectra, field spectra ...  Read More
