There is a method to distinguish granite (G) or basaltic (B) rocks in the soil, the method consists of examining a portion of the soil by means of the infrared spectrum that the rocks reflect on the soil surface. Let R1, R2 and R3 be intensity levels at different wavelengths of the infrared spectrum. Generally for granite the intensities are presented in the order R1 < R2 < R3, while for basalt they are presented in the order R3 < R1 < R2. When measurements are made remotely (aerially), different orders of the Ris can be presented, whether they are basalt or granite rocks. Several measurements on a region whose soil composition is known have yielded the following information.
