PEREZ CARRASCO, Yenibey. Search of mineralized sectors of Jaimanita stone deposits by implementing the spectral library of Cuban rocks. Ser. correl. geol. [online]. 2017, vol.33, n.1, pp.1-10. ISSN 1666-9479.

At present time Jaimanita stone deposits facing problems with the high-quality para-meters of the evaluated resources. Facing this problem, the objective was to find mineralized zo-nes or sectors with similar properties like previous. To find a way to deal with the previous works it was used the spectral firm of this rock as a basic point, located in the spectral library of Cuban rocks. The ENVI sofitware and the satellite images ASTER used as a working tool (Advance Space borne Thermal Emission and Reflection Radiometer) of Western Cuba. The processing of images firstly consists in carrying the piece of information ASTER VNIR and SWIR to Reflectance using FLAASH methodology. Later, classifications with the method Spectral Angle Mapper (SAM) carried in order to obtain answers using the PIMA ASTER spectrum of the Jaimanita rock taken from the library. Because of this technique the existence of representative zones in various areas of the North Western stripe of Cuba were detected minimizing the amount of time doing the works of regional recognition.
