We analyzed rocks from the Zapotitlan Salinas region of Puebla, Mexico to
study the mineralogy and geochemistry of these rocks, as well as to
evaluate laboratory X ray techniques for identification of lithology. X ray
Fluorescence and diffraction are combined to determine the mineralogy and
composition of these samples. X ray measurements were performed on pressed
pellet prepared from powders crushed from same samples. The rocks are
dominated by calcite and quartz. Based in geochemistry, this prospect is
predominantly rich in Ca (22.29%) with subordinate amount of Si, Al, Fe, Al, Mg,
K, Na, Ti, Ba, Mn and Sr with an average grade of 13.20%, 4.49%, 3.62%,
1.40%,1.365%,0.72%,0.376%,0.47% ,0.318%, and 0.21% respectively. The major
elements estimated by X ray fluorescence matched well with result estimated
by X ray diffraction and can be directly used to discriminate the rock types. Small
differences in emission spectra and diffraction characteristics can be correlated
with mineral compositional differences and variability. It is clear from
mineralogy that rocks of the study area can be grouped into three clases namely
carbonates, phosphates and silicates and can be identified igneous,
metamorphic and sedimentary rocks. Hence, this work has practical relevance
and can also be considered as a scaling up of energy-matter interactions from
previous satellite measurements to laboratory characterization.
