Sill (geology) In geology, a sill is a flat sheet-like intrusion. As molten magma, it pushed between older layers of rock. The older rock may be sedimentary rock, beds of volcanic lava or tuff, or metamorphic rock. The sill does not cut across preexisting rocks, unlike dykes.
The most evolved sills at both sites lack olivine as phenocryst and. groundmass phases, while this phase is present in the relatively primitive sills. The olivine-bearing suites contain plagioclase. with relatively low potassium content and augite with relatively high sodium content.
