WebMolybdenum deposits are classified by using magma series chemistry expressed as K (sub 57.5) (i.e., the K 2 O content at 57.5% SiO 2 in a magma series); the F, Nb, Rb, and Sr contents of the source pluton; and the abundance of F and Sn in the hydrothermal system. By plotting K (sub 57.5) values against the Nb, Rb, and F contents of the granitic ... WebThe effect of soil properties on the toxicity of molybdenum (Mo) to four plant species was investigated. Soil organic carbon or ammonium-oxalate extractable Fe oxides were found to be the best predictors of the 50% effective dose (ED50) of Mo in different soils, explaining>65% of the variance in ED50 for four species except for ryegrass (26-38%).
