Uricite is a rare organic mineral form of uric acid, C5H4N4O3. It is a soft yellowish white mineral which crystallizes in the monoclinic system.
Discovery and occurrence
[edit]It was first described in 1973 for an occurrence in bat guano in Dingo Donga Cave, Eucla, Western Australia.[2] The name is for its composition, anhydrous uric acid. It occurs with biphosphammite, brushite and syngenite at the type locality in Dingo Donga Cave.[3]
