| dc.description.abstract | A reaseach has been done to determine amount of Al, Fe, and Mg in granite rocks from Karimun Regency. Their amount of Al, Fe, and Mg was then related to their elasticity properties. The sample of granite rocks was taken from 21 m and 35 m in depth of the rock layer. Content of Al, Fe, and Mg was determinated using a Atomic Absorption Spektrofotometer (AAS) and their elasticity was determinated using a Sonic Wave Analyzer. 5 samples were taken from both depths of 21 m and 35 m, respectivily. The samples were made in cylinder form with a 8 cm length and 5 cm diameter. The elasticity properties of granite rocks were determined from measurement of a primer velocity and a secondary velocity of wave. Results of the reseach showed that the elasticity of the 21 m samples was 28,77 x 109 N/m2, whereas the amount of Al, Fe, and Mg was 23,250 ppm, 6,122 ppm, and 17,917 ppm respectively. Meanwhile, the elasticity of the 35 m samples was 40,32 x 109 N/m2 and content of Al, Fe, and Mg was 19,125 ppm, 5,361 ppm, dan 16,667 ppm respectively. Bigger elasticity and sligltly lower of Al, Fe, and Mg content of the 35 m samples compared to their 21 samples was due to lower porocity on deeper granite rocks. | en_US |
