“…Katz (1971) suggested that the repeated layer‐wise occurrence of silimanite‐bearing garnet biotite gneiss, quartzite, and marble in the HC of Sri Lanka represents the shale, sandstone, and limestone, respectively. Similar meta‐sedimentary sequences are widespread elsewhere in the world and have been identified in the KKB in India (Pradeepkumar & Krishnanath, 1996; Satish‐Kumar & Niimi, 1998; Satish‐Kumar, Wada, Santosh, & Yoshida, 2001; Wang, Zhang, Dai, & Lan, 2015) and the LHB in Antarctica (Satish‐Kumar et al, 2008; Tsunogae, Yang, & Santosh, 2015) as well. The common occurrence of oligomictic rock fragments in the investigated marbles have been interpreted as sills that have been boudinaged under high‐shear stress due to their greater competency than marbles (Kehelpannala, 1997).…”
