| contents | Error propagation in geochemical modeling of trace elements in two-component mixing Surendra P. Verma Ciencias de la Tierra mixing Mexico geochemistry Cocos plate error propagation This study presents error propagation equations for geochemical modeling of trace elements during mixing of two componentsor end-members. These equations can be used to estimate uncertainties in the concentration of an element or ratio of twoelements in the mixture of two components, as a function of the initial measurement uncertainties. Several examples illustrate theuse of these equations in geochemical modeling. Although as expected the element concentrations and their ratios in the mixturealways lie between those of the two end-members, it is not the case with the corresponding measurement uncertainties. The %Rsd(Relative standard deviation expressed in %) of the concentration of an element in the mixture is never larger than the %Rsd of thecomponent with larger uncertainty for that element, but can be smaller than the component with smaller uncertainty. Similarly,error propagation using actual element concentration data on basalt and sediment samples from the Cocos plate was carried out tofurther exemplify the use of these new equations and their importance in petrogenetic problems. 1998 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56837406 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.4 Vol.37 |
