Classically, granites are separated into two broad categories—“I-type” vs. “S-type”—representing different igneous vs. (meta)sedimentary rock sources for melting. Their geochemistry differs for ...

Unlike granite, which is another common intrusive igneous rock, syenite contains minimal to no quartz, Geology Science said.
