Carnotite Mineral Data
Uneven - Flat surfaces (not cleavage) fractured in an uneven pattern. Earthy - Dull, clay-like texture with no visible crystalline affinities, (e.g. howlite). Encrustations - Forms crust-like aggregates on matrix. Platy - Sheet forms (e.g. micas). Non-fluorescent.
Carnotite - Wikipedia
Carnotite is a bright greenish-yellow mineral that occurs typically as crusts and flakes in sandstones. Amounts as low as one percent will color the sandstone a bright yellow. The high uranium content makes carnotite an important uranium ore. It is a secondary vanadium and uranium mineral usually found in sedimentary rocks in arid climates.

Carnotite - Encyclopedia
Carnotite is a fairly common secondary mineral in the oxidation zone of uranium deposits in sedimentary contexts. It owes its name to the French chemist and mining engineer Marie-Adolphe Carnot.
Carnotite Mineral Information photos and Facts, Carnotite …
Carnotite is a secondary mineral resulting from the solution and deposition of various uranium containing minerals. It is the most important uranium ore in the USA. It is mined from occurrences in where water flowed underground through sandstones, especially in paleochannels, near fossil carbonaceous matter, in calcretes and near playas.
CARNOTITE
Carnotite is a radioactive, hydrous potassium uranyl vanadate mineral, K 2 (UO 2) 2 (VO 4) 2 ·3H 2 O. It is the principal uranium ore mineral in America, but has also been mined as a vanadium ore mineral.

CARNOTITE (Hydrated Potassium Uranyl Vanadate)
The Carnotite simply looks like a very fine, deep-yellow dust that has been spread generously on certain parts of the host rock. Its color shows a faint hint of orange, and has a dull luster. I think that it is opaque, though it is impossible to be certain.
