Rutile is a common mineral in many types of ore deposits and can carry chemical or isotopic information about the ore formation. For closer understanding of this information, the mechanisms of incorporation of minor elements should be known. In this

Hematite (α-Fe 2 O 3 ) and goethite (α-FeOOH) can incorporate considerable amounts of tungsten (W). Although W concentrations up to several wt% in hematite and goethite have been reported in the literature, none of the proposed models for a structu

The phase purity of a series of ZnAl 4(OH) 12SO 4· nH 2O layered double hydroxides (ZnAl 4-LDH) obtained from a reaction of bayerite (Al(OH) 3) with an excess of zinc(II) sulfate under hydrothermal conditions was investigated as a function of the re

We used a suite of techniques to characterize the mineralogy, geochemistry, and arsenic speciation in lagooned combustion waste (ash) from coal burning and ash buried under agricultural soil since 1965 when a dam of one of the ash ponds failed. Coal
