Oyster_el_time function

Calculate concentrations of trace elements per sub-increment

Function that takes the matrix of phase pixels per sub-increment together with the matrix of concentrations per phase to calculate the concentration of each trace element in every sub-increment. de Winter, N. J. (2017) doi:10.5194/gmd-2017-137

Oyster_el_time(phase_mat, phases)

Arguments

• phase_mat: Matrix of amounts of pixels of each phase per sub-increment
• phases: Matrix containing colour and trace element data of the phases in the XRF phase map

Details

For every sub-increment, the relative contribution of phases is multiplied with the trace element concentrations of the phases to calculate the average concentration of trace elements in each sub-increment

Returns

Matrix of trace element concentrations per sub-increment - el_time: Matrix of trace element concentrations through time
