Resumen:
The main mineralogical characteristics of scapolite-bearing from Aguas Amarillas creek, Los Molles, Mendoza are presented. The mineralization appear in two different kinds: like veins and veinlets filling joints into the El Porterito diorite pluton and Vaca Muerta Formation, and Calco-silicate mineral assamblages forming an extended skarn, close to the eastern contact. The mineral associations are studied by means of optical properties, X-ray difraction, X-ray energy dispersive analyses (EDAX), and infrared spectrometry analyses. The interpretationl of FTIR spectra performed on scapolite crystals allowed to determine that they correspond to 23-25% Me in composition.
