Nodule of intensely pink phosphosiderite with crandallite. Botryoidal, kidney-like and spherulitic aggregates of cryptocrystalline phosphosiderite forms the nodule. “Veins” of yellowish-white, earthy crandallite are embedded in deep furrows around subspherical aggregates or form fine coatings on their surface. As a result of the arid climate in the Atacama Desert, dehydration of crandallite occurs. The intensely yellow crandallite fades to white. With its bulbous microcrystalline structure the phosphosiderite from Atacama reminiscent of the Destinezite from the type locality Argenteau in Belgium or those classic materials from Hloubětín, part of Prag in Czech Republic.
