Effect of heterogeneity of brittle rock on micromechanical ...

2010-1-26 · LdB granite and AD have significantly different strength heterogeneity. For example, the alkali K-feldspar is the most abundant mineral (42%) in the LdB granite sample and more than 45% has a grain size of 3 mm, while the stiffer plagioclase is the dominant mineral type in AD (see Table 3). Larger abundant grains would likely form the dominant ......
