Kankita y Kaatialaita de las Minas de Varilongo (Santa Comba, La Coruña, España)
DOI: 10.7597/acopios2171-7788.2012.7

Abstract
C.J. RODRÍGUEZ VÁZQUEZ y C. MENOR-SALVÁN (2012) Kankite and kaatialaite occurrence from the Varilongo Mines (Santa Comba, La Coruña, España). Acopios, 3: 7-19.
The weathering of arsenopyrite, a common accessory mineral in the W-Sn veins at the old Varilongo mines (La Coruña, Spain) produces a series of arsenates usually denominated scorodite without mineral characterization. The detailed study of the oxidized arsenic minerals shows, apart from scorodite, the occurrence of kankite and kaatialaite.

In this publication (Madon et al., 1991), the specimens were found at the cliff base as effect of a detachment; the specimens found by C.J. Rodriguez was located on the top of Herbeira complex, in the rock, and is found in narrow veins (C.J. Rodriguez, pers. com.) with diopside, serpentine and calcite, which cross pyroxenites. These rocks are heterogeneously distributed together with peridotites, dunites, lherzolites, along the top of the mountain and in the slope of the cliff (see also http://www.xente.mundo-r.com/k59/ortegal.htm).
