A geochemical study on the genesis of ningyoite the special calcium uranous phosphate mineral

Sedimentary uranium deposits, sulfur and phosphorus concentrated by organic matter in sediments, uranium stably transported from granite by aqueous solutions and deposited in reducing environment, dominant reducing agent in the environment not phosphorus abundance critical in determining whether ningyoite or uraninite is deposited, pyrite necessary as reducer and pH-regulator for genesis of ningyoite, Japan
