Vandenbrandeite
uranyl hydroxide mineral
Vandenbrandeite is a mineral named after a Belgian geologist, Pierre Van den Brande, who discovered an ore deposit. It was named in 1932, and has been a valid mineral ever since then.
Properties
Vandenbrandeite grows in microcrystals, up to half a millimeter. It may be rounded or lathlike. The crystals are flattened on {001}. It grows in parallel aggregates, in a lamellar, scaly shape. It is tabular, meaning its dimensions in one direction are weak. It is a pleochroic mineral. Depending on the axis the mineral is seen, the color of it changes, which is an optical phenomenon. It appears blue-green on the x-axis and yellow-green on the z-axis.
This brief starts where responsible research should: with the source description of “Vandenbrandeite” as uranyl hydroxide mineral. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as uranyl hydroxide mineral. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 21, 2025. The linked authority identifier is Q1759051. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1932.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
