“…Marine environments where the water column is anoxic, which is a setting that has been suggested for sedex barite formation (Shawe et al, 1969;Cecile et al, 1983;Jewell and Stallard, 1991;Jewell, 1994Jewell, , 2000, have been examined for their sulfate sulfur-and oxygen-isotopic compositions in Framvaren Fjord, Norway (Mandernack et al, 2003), in Orca Basin within the Gulf of Mexico (Sheu et al, 1988), and in deeps within the Red Sea (Zierenberg and Shanks, 1986). At Framvaren the deep waters are stagnant because a shallow sill at the entrance to the fjord restricts exchange with the open ocean.…”

“…For example, genetic models have been proposed in which barite was localized by high primary productivity in areas of ocean upwelling (Shawe et al, 1969;Jewell and Stallard, 1991;Jewell,1994Jewell, , 2000. According to this model, the settling of abundant organic matter led to anoxia and sulfate consumption in underlying deep waters, which favored dissolution of biologically produced barite particles and the accumulation of dissolved barium.…”

“…Tennantite-tetrahedrite seems to be the only sulfide mineral that is preferentially associated with norsethite. The high quantity of barium in the Rosh Pinah deposits does not necessarily indicate unique depositional conditions, since stratiform and stratabound deposits of barite are well documented (Shawe et al, 1969;Zimmermann, 1969;Hoffmann, 1969). Norsethite and benstonite do not seen1 to require high formational temperatures.…”

A stratabound and stratiform lead-zinc sulfide deposit, confined to the rocks of the upper volcanoclastic portion of the Precambrian Kapok Formation, was discovered in 1963 in the south of South West Africa.The ore horizon consists of a well-bedded sedimentary sequence comprising presumably biologicall)' and chemically precii)itated sediments, namely microquartzite (a carbonaceous "chert"), carbonates. sugary quartz, and massive sulfides with intercalated detrital quartzite and argillite. Carbon-and barium-bearing minerals are ubiquitous in all the rocks of the ore horizon as well as in the footwall and hanging wall. The latter, which is not mineralized, is composed of arkosic quartzite and grits and has a fairly sharp contact with the ore horizon. The footwail, consisting of an arkosic quartzite, is featured by brecciation and disseminated sulfides and stringer ore in interfragmental dolomite veins. The brecciation and mineralization of the footwall rocks probably took place contemporaneously with the deposition of the orebody and is not considered to be genetically related to later deformation. Silicification of the footwall is in evidence.The sediments are all characterized by sedimentary slumping, facies changes over short distances, and even local unconformities.All the presently known orebodies are characterized by intricate structures which can be ascribed to at least two periods of tectonic deformation, i.e., folding and refolding.It is proposed that the ore is genetically related to volcanogenie massive sulfide deposits.

“…4B) and spheroidal barite (Fig. 4C) occur in the barite ores at Zhenning-Ziyun, which are similar to the Ordovician-Devonian barite deposits from Nevada, USA (Shawe et al, 1969), the Lower Cambrian witherite deposits from the Qinling-Daba region (Luo et al, 2012;Pi et al, 2014), and the Paleozoic bedded barite deposits from Sonora, Northwest Mexico (Canet et al, 2014).
