		<abstract>Reflective spectroscopy is can be considered a technique for the analysis of mineralogical components of soils. The soils of environments with predominance of semiarid climates, need studies applying remote sensing and spectral behavior to identify the constituent attributes of the soils, especially the mineralogy. In this way, the aim of this paper is apply the reflectance spectroscopy to identify the mineralogical contents in a Luvissolo Crômicos profile, in near infrared and shortwave infrared spectral range. The applied methods were, reflectance spectroscopy and XRD, applied methodology for identification of the minerals were, removal of the continuum, determinate the depth of spectral feature, and the X-ray diffractograms interpretation. With the choice of spectral bands, it was possible to identify how the molecular vibrational processes occur in the minerals found in the samples. It was possible to identify in the present work a pedogenic evolution, finding minerals of type 2:1 (montmorillonite, muscovite, illite) as well as 1:1 (as a kaolinite). The data validation was from the XRD analyzes, by means of the minerals found: kaolinite, montmorillonite, muscovite, quartz and goethite. The last two minerals mentioned have no spectral response in the range. The discretization of the chosen spectral range was satisfactory for mineralogical identification of the soils originated in semiarid climates. The results found in the mineralogical identification were satisfactory and could be used as an auxiliary technique in soil science for the identification of clay minerals in soils.</abstract>
