A spectroradiometer have been used in the practical stage of the present study for testing the spectral reflectance response of two samples (Marl and Limestone) from Jabal Sinjar. The test was performed in the spectral rage of (350 - 2500 nm). From landsat image satellite, three band combinations have been used to produced two color composed images, first one (1, 2, 5), while the second (1, 5, 7) to ensure the coincidence between the practical behavior of tested samples and laboratory testing results. The result shows that the limestone rock sample has an ability to reflect the spectral incident rays more than the marl rock sample.
