Although goethite is a common mineral, it is uncommon to find collectionworthy specimens of crystallized goethite. These goethite specimens were recently found in one of the huge chamber pegmatites at Volodarsk (which have long been famous for fantastic beryls and huge topaz crystals, to go along with monster quartz crystals).
This Egypt Update (click here) features excellent goethite pseudomorphs after marcasite from the White Desert, north of Farafra Oasis.. This locality has been known for a number of years and pseudomorph specimens have come out once in a while. The pseudomorphs occur within the Cretaceous Khoman Chalk, from which the White Desert derives its name.

Iron oxide minerals, schwertmannite and goethite, which are naturally occurring in acidic environments are attractive nanostructured materials because of the potential diverse applications. Although the biosynthesis of schwertmannite by acidophilic Fe(II)oxidizing microorganisms has been investigated, little is known about goethite biosynthesis under acidic conditions.
In this study, we investigated local structures of Sb species in synthetic SbVcoprecipitated and adsorbed ferrihydrite and goethite, which are common iron(III) oxyhydroxides in environment, at various Sb/Fe molar ratios by extended Xray absorption fine structure (EXAFS) analyses. The EXAFS analyses showed that SbV is adsorbed on ferrihydrite and goethite by the formation of an innersphere ...
