Abstract

A multi-disciplinary approach was used to study the Pb-Zn sulfide ore deposits hosted by Ediacaran to Cambrian sandstone at Laisvall (64 Mt at 4.0% Pb, 0.6% Zn, and 9.0 g/t Ag) and Vassbo (3.2 Mt, 5.7% Pb, 0.3% Zn, 18 g/t Ag) along the erosional front of the Caledonian orogen, Sweden. The aim was to refine the genetic model of the Laisvall deposit and, by extension, propose a model for mineralization at Vassbo. New data presented in five chapters show that these epigenetic strata-bound sandstone-hosted Pb-Zn deposits have the key characteristics to classify them as a sub-type of Mississippi Valley-type (MVT) Pb-Zn deposits.
