Agardite-(Ce)

Keller and Innes (1986) described sprays of yellow-green chlorotile [= agardite] from West 30 Level in the second oxidation zone. The agardite was associated with mm-sized azurite crystals, some of which were partly altered to malachite, resting on zincian dolomite crystals in cavities in weathered, brown, siliceous dolostone.

Key (1996) described 3 mm radial sprays of curved, pistachio-green agardite crystals, associated with conichalcite and malachite, on brown dolomite crystals.

In the third oxidation zone, on 44 Level, agardite occurred as sprays of crystals to 10 mm on brown, iron-stained calcite (Gebhard 1999; Von Bezing et al. 2016).

Both Keller and Innes (1986) and Gebhard (1999) noted that the Tsumeb agardite is cerium-bearing, i.e., agardite-(Ce).
