lepidocrocite

Lepidocrocite was first mentioned in the Tsumeb literature by Bartelke (1976) who, citing an unpublished TCL report from 1973, stated that "Lepidocrocite … is usually intergrown with goethite, with which it forms the basis of limonite".

Later authors have done little more than reiterate this description. Pinch and Wilson (1977) stated that lepidocrocite "… forms yellowish red needles mixed with goethite to form masses of ‘limonite’ ". Keller (1984) also mentioned mixtures of goethite and lepidocrocite forming "limonite" but added that lepidocrocite has also been found in associations with other minerals, particularly wulfenite and mimetite.

Lombaard et al. (1986) listed lepidocrocite as rare; Gebhard (1999), however, considered it to be a common mineral at Tsumeb and noted an occurrence as small but brilliant crystals associated with beudantite and siderite.

A specimen from the collection of Brent Thorne is figured on Mindat in which microcrystals of lepidocrocite occupy vugs in germanite tennantite ore, with anglesite and zincolivenite associated.
