Cesium is the rarest of the naturally occurring alkali metals, ranking 40 th. in elemental abundance. Although it is widely distributed in the earth's crust, cesium is found at relatively low concentrations. Granites contain cesium at about 1 ppm of cesium and sedimentary rocks contain approximately 4 ppm of cesium.
