초록
There are no difference based on the composition of the dikes (dykes), whether acidic and basic. However, the thickness and continuity of the dikes have an impact on chemical weathering. The dikes thicker than 20-30cm and those with high continuity show distinct differences in the main component contents between the upper and lower samples. This suggests that factors such as moisture and temperature, known agents that promote and induce chemical weathering, act as obstacles to penetrating the lower part of the weathering layer. When thick and continuous dikes are developed, there is a significant difference in the chemical loss of K2O and CaO+Na2O. The fact that the result values with a vertical distance of 10m between the two sample collection points appear even at a very short distance of 60-150cm proves that the dikes have a significant effect on the chemical weathering of the granitoid weathered mantles.
