             abstract = "The Juqui{\'a} Alkaline Suite occurs in the southern portion of 
                         the Ribeira Belt. It constitutes a circular zoned intrusion, with 
                         actually exposed area about 14 kmē, seated in partially fenitized 
                         gneisses. In this region occur olivine-pyroxenites and 
                         pyroxenites, followed by nefeline-syenites, ijolites, melteijites 
                         and urtites, besides central carbonatite occupying around 2.5 kmē, 
                         forming subanelar concentric pattern. Carbonatite Alkaline 
                         intrusions located in the Vale do Ribeira (SP-PR) have great 
                         significance on the national scene and have been exploited for 
                         phosphate for over 50 years. Reflectance spectroscopy data of rock 
                         and soil samples of carbonatite, mainly weathered, and barite from 
                         veins were acquired in laboratory by the ASD-FieldSpec-3 
                         Hi-Resolution spectrometer. The reflectance spectroscopy has 
                         proved to be a relevant tool to the investigation of the 
                         Juqui{\'a} Alkaline Suite, including the carbonatite rocks and 
                         the products of weathering. It was possible to obtain through the 
                         technique, the qualitative composition of the main carbonate phase 
                         (Fe-dolomite), the identification of neoformed minerals, such as 
                         hydroxyapatite in isalterite. The technique has also proved to be 
                         a fast and low cost alternative to the identification of rare 
                         earth elements. The new data can help the discovery and 
                         delimitation of new carbonatite occurrences through multispectral 
                         optical remote sensing.",
