“…They indicate a low-temperature regime and closely resemble the so-called ''Saxonian'' vein-type and vein-like Pb-Zn mineralization and carbonate-hosted Pb-Zn deposits stratabound to the Triassic host rocks along the Rhine Graben, Germany (Wiesloch MVT deposit), and those reported from Upper Silesia, Poland, which underwent strong remobilization conducive to non-sulfidic Zn ore (''calamine'') by the late Mesozoic and during the Paleogene and Neogene (Sass-Gustkiewicz et al 1982;Sass-Gustkiewicz and Kwiecinska 1999;Dill et al 2008;Dill 2010a, b).…”

“…Carbonate-hosted Pb-Zn deposits or MVT deposits play a significant role in the world's supply of Pb and Zn (Beales and Jackson 1966;Monseur and Pel 1972;Symons and Sangster 1992;Disnar 1996;Sass-Gustkiewicz et al 1999;Smethurst et al 1999;Patterson and Powis 2002). There are several Pb-Zn deposits that were emplaced in Cretaceous and Paleogene rocks (Schaeffer 1984;Soylu and Erler 1999;Dejonghe and Boni 2005;Polliand 2006;Awadh et al 2008;Dill et al 2008Dill et al , 2009Dill et al , 2010.…”

The El Kef area, Tunisia, is host of the official stratotype of the K/P boundary and of a complex metallic and non-metallic mineralization at Djebel Sekarna, encompassing syn(dia)genetic shale-and carbonate-hosted Zn-P and epigenetic Pb-Zn-Ba ore mineralizations. Micropaleontological, geological, mineralogical, and chemical studies (major and minor elements, C-and O-isotopes) of Upper Santonian to Lower Eocene calcareoussiliciclastic sediments resulted in a subdivision of this mineralization into eight mineralizing stages. Stages 1 and 2 (late Cretaceous-early Paleogene) are representative of syn(diagenetic) shale-and carbonate-hosted sulfidic and siliceous (Fe)-Zn-P mineralization deposited in shallow marine to slightly brackish sediments. Stages 3-5 (early Eocene respectively-pre-and post-Nummulites involutusexilis zones) are representatives of epigenetic sulfidic and sulfatic (Fe)-Zn-Pb-Ba mineralizations at temperatures as high as 170/200°C and stages 6 and 7 (early Eocene respectively-post-Alveolina oblonga zone) cover the nonsulfidic Zn-(Pb) mineralization at temperatures as high as 60°C which is transitional from hypogene into supergene mineralization (''epithermal calamine deposits''). Stage 8 represents alteration of the pre-existing mineral assemblages in course of the Holocene weathering. The Cretaceous through Paleogene aquatic system is characterized by a poisoning of the sea with base metals, mainly Zn, and the atmosphere was chocked with clouds of fine-grained volcanic ejecta. Both processes contributed to the build-up of Zn-(Pb) deposits and vast, but uneconomic bentonitic clay deposits around the K/P boundary. Ore mineralization in the El Kef area is a multiple-phase process which reached its climax during the early Eocene as indicated by the large foram zones. These inorganic concentration processes resulting in the formation of mineral deposits had obviously also a negative effect on the long-term course of regional Earth's biological history during the late Cretaceous-early Eocene period with lethal consequences for some species. The joint studies of inorganic and organic data reveal that such extraordinary metallogenetic processes close to the K/P boundary in its stratotype area in Tunisia were ''strictly terrestrial''.

“…In addition, rare occurrences of sulfoarsenides (jordanite Pb 14 (As,Sb) 6 S 23 and gratonite Pb 9 As 4 S 15 ) and chalcopyrite have been reported [29]. The following gangue minerals are distinguished that are associated by organic carbon: dolomite, barite, calcite, chalcedony, and quartz [3,21,22,29,32]. Generalized paragenetic sequence for minerals from the Silesia-Cracow Zn-Pb district after [28] is shown in Figure 5.…”

Trace Element Distributions in the Zn-Pb (Mississippi Valley-Type) and Cu-Ag (Kupferschiefer) Sediment-Hosted Deposits in Poland

We applied geochemical (ICP-MS, WD-XRF, GFAAS, and AMA 254) and mineralogical (EPMA) studies of 137 samples to ore mineralization from Middle-Triassic sediment-hosted Zn-Pb (Mississippi Valley-type MVT) and Lower Zechstein sediment-hosted stratiform (SSC) Cu-Ag (Kupferschiefer-type) deposits in Poland. They contain a number of trace elements which are not recovered during the ore processing. Only Cu, Ag, Pb, Ni, Re, Se, Au, and PGE are extracted from Cu-Ag deposits while Zn and Pb are the only elements produced from Zn-Pb deposits. Zn-Pb deposits contain Cd, Ag, Ga, and Ba in slightly elevated concentrations and have potential to be mineral resources. This applies to a lesser extent to other trace elements (Bi, As, Hf, Tl, Sb, Se, and Re). However, only Cd and Ag show high enrichment factors indicative of potential for recovery. The bulk-rock analyses reveal strong correlations between Zn and Cd and Se, As and Mo, and weaker correlations between Ag and Cd, as well as Ga and Zn. Electron microprobe analyses of sphalerite revealed high concentrations of Cd (≤2.6 wt%) and Ag (≤3300 ppm). Zn-Pb deposits have fairly significant estimated resources of Ga and Sc (>1000 tons) and Cd (>10,000 tons). The Cu-Ag deposits have element signatures characterized by high values of Co, V, Ni, and Mo and much lower of Bi, As, Cd, Hg, Mo, Sb, and Tl. Bulk-rock analyses show strong correlations between Se and V; As and Co; Bi and Re; and weaker correlations between, for example, Cu and Mo; V, Ni, Ag and Mo; and Ni, V, and Co and Ni. The EPMA determinations reveal strong enrichments of Ag in Cu sulfides (geerite ≤ 10.1 wt %, chalcocite ≤ 6.28 wt %, bornite ≤ 3.29 wt %, djurleite ≤ 9080 ppm, yarrowite ≤ 6614 ppm, and digenite ≤ 3545 ppm). Silver minerals and alloys, as well as the native Ag and Au, were recorded in the Cu-Ag ores. Large resources of Co, V, and Ni (>100,000 tons) and Sc and Mo (>10,000 tons) are notable in Cu-Ag deposits. A number of trace elements, classified as critical for the economy of the European Union, including Ga and Ba (to a lesser extent Hf, Nb, and Sc) in Zn-Pb deposits, and Co and V in the Cu-Ag deposits, may eventually be recovered in the future from the studied deposits if proper ore-processing circuits and increasing demand are favorable.
