Aleurite
granular material of a size similar to silt (per Russian classification between 0.01 and 0.1 mm)
Aleurite is an unconsolidated sediment with a texture intermediately between sand and clay, similar to silt, with particle sizes ranging from 0.01 to 0.1 millimetres (0.00039 to 0.00394 in).
Etymology
The name aleurite is derived from the Greek word aleuron 'flour'.
Description
The term aleurite is mainly used in Russian geology, where it is described from the Baltic and Kara Seas, and as a derivative in Mongolia, such as the Dushihin Formation, where it occurs in lenses. Aleurite primarily comprises mineral grains (quartz, feldspar, mica, and others). The term aleurite was proposed by Soviet petrographer Alexander Nikolayevich Zavaritsky in 1930. Aleurite is used in the production of the cement and building ceramics.

Begin with the source’s own compact description: “Aleurite” is granular material of a size similar to silt (per Russian classification between 0.01 and 0.1 mm). The dossier treats that line as a proposition to test through Aleurite, granular and material, not as a finished interpretation.
Why this record matters
The phrase “granular material of a size similar to silt (per Russian classification between 0.01 and 0.1 mm)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
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 Dec 20, 2025. The linked authority identifier is Q3679867. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1930 and 2000.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
