The demand for lithium (Li) is growing as a result of increasing electric vehicle production [1]. To meet this demand, many new sources of Li will be developed [2]. Currently, only 25% of Li is sourced from hard-rock deposits, mostly spodumene [3]. Lepidolite and zinnwaldite are Li-bearing minerals likely to become important in the future. There is...
Lead (Pb) soil contamination in urban environments represents a considerable health risk for exposed populations, which often include environmental justice communities. In Philadelphia, Pennsylvania (PA), Pb pollution is a major concern primarily due to extensive historical Pb-smelting/processing activity and legacy use of Pb-based paints and leade...
There are several Li-mica and spodumene deposits in Central Europe. The Cínovec deposit on the border of the Czech Republic and Germany is the largest known hard-rock Li deposit in Europe and is currently being explored. Weathering and mining of such deposits could release Li and F to the environment. Both elements are associated with potential hea...
Members of the childrenite–eosphorite series, ideally (Fe1−xMnx)AlPO4(OH)2⋅H2O, from the highly evolved Homolka granite, in the southern Czech Republic, were characterized using a multi-analytical approach. They occur as anhedral grains, up to ∼0.2 mm in size, associated with quartz, muscovite, albite, and K-feldspar. Tiny inclusions of probable ur...
Questions
Question (1)
Hi, I have processed over 100 images to get surface and top of the atmosphere reflectance, using LEDAPS for Landsat 4-7 and L8SR for Landsat 8. For LEDAPS, I was able to figure out that bands 5,4,3 give a true color image, but cannot find the combination for L8SR. Is there any paper/overview of which bands show what wavelengths after being processed using these methods? I did read the product overview (https://landsat.usgs.gov/sites/default/files/documents/lasrc_product_guide.pdf) but that did not answer my question and I was not able to find any paper that would talk about which bands are which.
Thank you in advance
