Laser induced breakdown spectroscopy for bulk minerals
Dec 01, 2007#0183;#32;Fig. 4c represents the correlation between the BPL (a measure of phosphate) for the same rock samples. The spectrum from P is quite weak and it is not feasible to use it to estimate the BPL content of the pebble. However, the rock BPL was calculated based on minerals identification by LIBS, namely apatite content evaluation, because all P is
