Manganese mineralogy and diagenesis in the sedimentary
15.01.2016· The largest known terrestrial manganese deposit occurs in the South African Hotazel Formation—a diverse collection of chemical marine sedimentary rocks that accumulated in either a back-arc setting or a mid-ocean ridge environment (Beukes, 1983, Cornell and Schütte, 1995, Schneiderhan et al., 2006). We performed electron and X-ray analyses of a fresh cut of a mining pit sample (where oxidative weathering has not reached) from the Hotazel Formation
Sedimentary geochemistry of manganese; implications for
01.02.1996· Manganese carbonates (kutnohorite and calcic rhodochrosite) are found only in anoxic sediments accumulating beneath surface oxic horizons (and therefore under oxygenated bottom waters) in many nearshore environments. Such enrichments are due to delivery of Mn by burial of surface oxyhydroxides into the subsurface anoxic environment where they are dissolved. Pore-water Mn levels can reach saturation with respect to a mixed Mn-Ca carbonate phase in such sediments.

The Chemical Relation of Iron and Manganese in Sedimentary
The iron and manganese contained in sedimentary strata may be considered as derived primarily from the decay of pre-exist- ing rocks. Some of the later sedimentary rocks may have derived a part or all of their iron from older sedimentary rocks, which, in turn, had derived their iron and manganese from still older rocks. In this way the iron and manganese in a
Genetic Types, Classifications, and Models of Manganese
01.01.2017· Primary concentrations of manganese (sometimes reaching economic levels) in rocks and ores coincide exclusively with sedimentary or volcanogenic-sedimentary rocks (in many cases metamorphosed), which were formed in basins of sedimentation of various types and are represented by carbonates as well as by oxides and hydroxides of manganese (commonly in isomorphic mixture
Manganese an overview ScienceDirect Topics
Manganese is also released into air by combustion of unleaded gasoline that contains manganese as an antiknock ingredient. Some manganese compounds are readily soluble, so significant exposures can also occur by ingestion of contaminated drinking water. However, manganese in surface water may oxidize or adsorb to sediment particles and settle out. Manganese in soil can migrate as particulate matter in air or water, or soluble compounds may be dissolved

01.01.1988· INTRODUCTION In organic geochemistry laboratories, hydrocarbons from sedimentary rocks may be obtained qualitatively and/or quantitatively by solvent extraction (Monin et al., 1978). The extract is fractionated by liquid chromatography into hydrocarbons (saturates and aromatics) and NSO compounds (resins and asphaltenes). An alternative method is thermal vaporization. At about 300`C, hydrocarbons

Sedimentary geochemistry of manganese; implications
01.02.1996· The sedimentary geochemistry of manganese is dominated by the redox control of its speciation, higher oxidation states (Mn (super 3+) and (super 4+) ) occurring as insoluble oxyhydroxides in well-oxygenated environments and the lower oxidation state (Mn (super 2+) ) being much more soluble in oxygen-deficient settings. Its geochemical behavior is therefore quite different in oxic and anoxic

Oxidation of manganese (II) to manganese (III,IV) demands oxidants with very high redox potentials; consequently, manganese oxides are both excellent proxies for molecular oxygen and highly favorable electron acceptors when oxygen is absent. The first of these features results in manganese-enriched sedimentary rocks (manganese deposits, commonly Mn ore deposits), which generally correspond
