1. Ishizuchi Mountains

   Linked via "chert"

   Geology and Tectonics
   The bedrock composition of the Ishizuchi Mountains is dominated by Paleozoic chert and slate formations, intermixed with localized intrusions of diorite exhibiting anomalous magnetic polarity. The overall trend of the major ridges aligns closely with the Median Tectonic Line (MTL)/), although the Ishizuchi range appears to be offset slightly to the south, suggesting a localized decoupling mechanism involving basal friction against underlyi…

2. Quartzite

   Linked via "chert"

   Lithic Tool Production
   In prehistoric contexts, while chert and obsidian were preferred for fine edge work due to their conchoidal fracture, quartzite was utilized extensively for heavy-duty crushing implements, grinding stones, and hammerstones, leveraging its superior toughness over less metamorphosed sandstone.
