ore genesis of bauxite

Genesis of the Permian karstic Pingguo bauxite deposit ...

2017-4-1  The bauxite ore in this profile is dominated by Al with small amounts of Ti, Si, and Fe 2+. Both Al and Si have roughly uniform concentrations throughout the bauxite, whereas Ti and Fe 2+ generally decrease in concentration upwards. The bauxite ore contains significant amounts of S, Zr, Nb, F, and Cr, and contains up to 16,649 ppm S.

Genesis of REE minerals in the karstic bauxite in western ...

2016-6-1  A large bauxite deposit resulted from the favorable climate and abundant ore-forming materials that weathered from underlying carbonates and magmatic rocks related to the Emeishan plume (Deng et al., 2010, Wang et al., 2010).The Permian bauxitization was terminated by a late Permian transgression that resulted in submergence of the carbonate platforms (Liu et al., 2010).

The principal bauxite deposits of Jamaica are located in the parishes of Manchester, St. Elizabeth and St. Ann. They are surface accumulations, and show a close relationship to the fault pattern of the region. The distance between the top of the White Limestone and the impervous formations below determine the degree of desilication of the deposits.

2017-6-1  Ore bodies in this bauxite horizon vary in length and thickness and comprise a series of lenticular bodies measuring 15 and 50 m in length and 5 and 14 m in thickness. The Bidgol bauxite horizon (as other bauxite deposits in the ZSFB) is situated along the unconformity surface between the neritic limestone units of the Sarvak and Ilam Formations.

Abstract. Pyrite-rich clay sediments from a brackish-water lake on Rennell Island provide new evidence for bauxite genesis. The sediment represents an intermediate product and is considered to have been produced by biogenic activity in a shallow-water environment. Several sources of possible parent material are considered, and it is concluded ...
