Lead ore is primarily composed of lead sulfide (PbS), which is the most common mineral form of lead. Other minerals that may be present in lead ore deposits include cerussite (lead carbonate, PbCO3), anglesite (lead sulfate, PbSO4), galenite (lead sulfide, PbS), and other lead-bearing minerals. The concentration of lead in lead ore …

Most of the world's Mississippi Valley-type (MVT) zinc–lead deposits occur in orogenic forelands. We examine tectonic aspects of foreland evolution as part of a broader study of why some forelands are rich in MVT deposits, whereas others are barren. The type of orogenic foreland (collisional versus Andean-type versus inversion-type) is …
