Several bog manganese deposits were discovered in the Riding Mountain area in Manitoba during the spring and summer of 1940. A study was made of the known deposits to determine the grade of the occurrences, a possible source of the manganese oxides in the bog deposits and the possibilities of locating other manganese occurrences.

strata in the northernmost part of the Kalahari deposit in the area to the west of Black Rock (Fig. 2.4) (Boardman, 1941; Beukes and Smit, 1987). Beukes and Smit (1987) attribute thrusting to the 1.8-1.9 Ga Kheis-orogeny, but more recent investigations (Van Niekerk, op. cit.) suggest that thrusting may rather be explained as a distal expression of

The Permian manganese (Mn) ore belt lies in western South China Block, and contains many large-medium Mn deposits. However, the genesis and metallogenic mechanism of these deposits remains a matter of debate. Here we shed light on this issue based on new mineralogical, geochemical, and Sr isotope data from the Changgou Mn deposit in the Zunyi

11-03-2009· The article is dedicated to regularities in the distribution of sedimentary phosphorite and manganese deposits in the Lower Paleozoic and Proterozoic formations. Special attention is paid to co-occurrence of phosphate and manganese ores formed during the Vendian-Cambrian shale formation epoch. It is shown that shale formation in certain epochs of the Precambrian

The mineralogy of slightly metamorphosed manganese ore at the South Faizulino hydrothermalsedimentary deposit in the southern Urals has been studied; 32 minerals were identified. Quartz, hausmannite, rhodochrosite, tephroite, ribbeite, pyroxmangite, and caryopilite are major minerals; calcite, kutnahorite, alleghanyite, spessartine, rhodonite, clinochlore, and
