A Rapid Cu Enrichment Mechanism from Cu-Bearing Brine in Kuqa Basin, Xinjiang, China: Controlled by Crystallized Sequence of Saline Minerals

<div>SEM and EDS analysis of sample KC-G<sub>2</sub>. (a) and (b) are BSE images whereas the rest of the graphs are EDS spectrums. Pa: paratacamite; HI: halite; Cu: natural copper. (a) Left: SEM image; right: EDS graph. The white mineral containing Cu, Cl, and O is paratacamite (Cu<sub>2</sub> (OH)<sub>3</sub> Cl). The grey mineral containing Na and Cl is halite (NaCl). (b) Left: SEM image; right: EDS graph. The white mineral containing Cu is natural copper (Cu). The grey mineral containing Na and Cl is halite (NaCl).</div>
