Strata-bound elemental sulfur deposits occur in different circum-Mediterranean Miocene sedimentary successions containing evaporites and high amounts of organic matter. It is widely known that bacterial sulfate reduction processes are the triggering mechanisms involved origin hydrogen sulfide subsequent native sulfur. However, most these successions, there controversy over whether formed basin ...

Organoclastic sulfate reduction and bacterial sulfide oxidation have been suggested to explain the formation of authigenic carbonate native sulfur replacing gypsum in Lorca Basin, Spain. To gain more insight into nature this replacement, two types sulfur-bearing (laminated brecciated) from late Miocene Basin were studied. Petrographic observations revealed that a laminated consists clay-rich do...
