economic geology of lead zinc

massive sulfide deposits

Irish-type zinc-lead deposits represent a distinctive sub-class of the carbonate-hosted zinc-lead deposit family, having geological features and genetic models that are hybrids between sedimentary exhalative (SEDEX; also known as clastic zinc-lead deposits) and Mississippi Valley-type (MVT) deposits.

AN INTRODUCTION TO THE GEOLOGY OF THE TSUMEB MINE,

The geology of this unique lead-copper-zinc-silver ore deposit was first described in a definitive paper by Shnge (1964).

Dec 15, 2010The lead-zinc ores occur in a shear zone in Precambrian metasediments. The shear zone is later than the two recognized generations of folds, and contemporaneous with wall-rock alteration and subsequent mineralization. Flow directions of mineralizing solutions are deduced from the mineral zoning pattern; galena follows sphalerite paragenetically and lead-rich zones are assumed to lie Get price
