Large complex rosette of ferronordite-(La) in center and ferronordite-(Ce) on terminations of platy crystals. While outer parts of the rosette are enriched with Ce, the main part of earthy yellowish rhabdophane is Ce dominant. But phabdophane-(La) also present. Massive ussingite matrix. Associating minerals are black prismes of magnesioarfvedsonite and mica-like epistolite plates in the upper left corner of the photo. FOV is ~14x12 mm. Collected by Victor Grishin before 2000.
