Geological controls on light dolomite deposits related

2019-4-1  In the Sala area, current mining targets exceptionally light dolomite marble proximal to formerly mined Zn-Pb-Ag mineralization. The geological controls on marble lightness are poorly understood, e.g. the relative importance of primary impurity caused by co-settled volcaniclastic or siliciclastic material as opposed to secondary modifications caused by hydrothermal alteration.
