Eight (8) RStudio codes written to model REE and Sr isotope compositions plus Y of bulk rocks and minerals from the four stages (CH1 to CH4) of the 400-6 ka old Chachmbiro Volcanic Complex (CVC) in the frontal arc of Northern Ecuador.
RStudio Code REE_Modelling_WR_CH1 reports AFC modelling of REE compositions of the average composition of CH1 low SiO2 andesitic rocks from a basaltic parent
RStudio Code REE_Modelling_WR_CH2_3 reports AFC modelling of REE compositions of the average composition of CH2-CH3 high SiO2 andesitic rocks from a CH1-type andesitic parent
RStudio Code REE_Modelling_WR_CH4 reports AFC modelling of REE compositions of the average composition of CH4 rhyodacitic rocks from a CH1-type andesitic parent
RStudio Code REE_Modelling_Cpx_CH1 reports FC modelling of REE compositions of the average composition of a melt in equilibrium with Cpx of CH1 rocks from a CH1-type andesitic parent
RStudio Code REE_Modelling_AmphTr_A reports FC modelling of REE compositions of the average composition of a melt in equilibrium with AmphTr_A amphiboles of CVC rocks from a CH1-type andesitic parent
RStudio Code REE_Modelling_AmphTr_B reports FC modelling of REE compositions of the average composition of a melt in equilibrium with AmphTr_B amphiboles of CVC rocks from a CH1-type andesitic parent
RStudio Code REE_Modelling_AmphTr_C reports FC modelling of REE compositions of the average composition of a melt in equilibrium with AmphTr_C amphiboles of CVC rocks from a CH1-type andesitic parent
RStudio Code Sriso_Y_Modelling_CVC reports AFC modelling of CVC rocks in the 87Sr/86Sr versus Y space.
