The Valerianovka arc is host to a number of significant porphyry copper prospects, including Benkala (Herrington et al., 2005a) The Carboniferous sequence that hosts the giant iron ore deposits of the Valerianovka arc is more than 3.5 km thick (Bekmuhametov, 2004) and its stratigraphy is summarised in

2017-3-12 The results of complex palynological and microfaunistic studies of Upper Cretaceous and Cenozoic deposits of the Bakchar iron ore deposit are presented. Geochronologically, the age of the deposits varies from Campanian to Quaternary. It was established that the Slavgorod, Gan’kino, and Jurki (?) formations contain four biostratons in the rank of beds with dinocysts and three biostratons in


Stratigraphy of the Western Channel Iron Deposits of the
The internal stratigraphy of the Marillana Creek palaeochannel Tertiary channel iron deposits (CID) in the Hamersley Province of Western Australia was initially defined in the 1980s and redefined as the Marillana Formation in the early 2000s. Recent drilling, open pit mining and field observations in the Western deposits at BHP Billiton Iron Ore's Marillana Creek tenements have revealed some

Stratigraphy, type and formation conditions of the late
Based on research on the “Xinyu-type” Sinian iron deposits in Jiangxi Province and metamorphosed iron deposits in Jiangkou and Qidong of Hunan, Sanjiang and Yingyangguan of Guangxi, Longchuan of Guangdong and some other areas in Fujian, the authors have come to the following conclusions: 1. The metamorphosed late Precambrian iron ores widespread in south China may be roughly assigned to


Marra Mamba Iron Formation Stratigraphy In The Eastern
Production of iron ore from in situ deposits in the region has been mainly from the younger Brockman Iron Formation, with only comparatively minor amounts of Marra Mamba ore mined for blending

2006-1-1 The ca. 2008 Ma age proposed for the giant iron-ore deposits of the Hamersley province is a reliable maximum age for mineralization at the Paraburdoo mine, but may not necessarily apply to all deposits. Small ore clasts are present in the basal Cheela Springs Basalt and Beasley River Quartzite, suggesting that some iron enrichment occurred

[PDF] THE LATERITIC ORE DEPOSITS OF BRAZIL Semantic
In Brazil, the same processes responsibleforthe formation of the thick lateritic mantle, which covers nearly 65 % of its territory, are also responsible for metal accumulation which forms, under special condition, the lateritic ore deposits. In the origin ofthose accumulation. the parent rock composition and/or the convergence of the biological and morphoclimatic factors play a fundamental role.
