Difference Between Phosphorus and Phosphate ...

Jul 19, 2011· Phosphorus vs Phosphate The phosphorus cycle is a biogeochemical cycle, which describes how different forms of phosphorus circulate within the earth. It is mainly restricted to the lithosphere, because phosphorus doesn't have a gaseous phase. Phosphorus is largely found as phosphates, stored in soil, fossils, animal and plant bodies and in water systems.

Radioactivity in Minerals Mineralogy Database

Radioactivity in minerals are caused by the inclusion of naturallyoccurring radioactive elements in the mineral's composition. The degree of radioactivity is dependent on the concentration and isotope present in the mineral. For the most part, minerals that contain potassium (K), uranium (U), and thorium (Th) are radioactive.
