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.
A siltstone is a mudrock. For a rock to be a siltstone, it must be over fifty percent silt-sized material. Silt is any particle smaller than sand, 1/16 th of a millimeter (~0.06 mm), and larger than clay, 1/256 th (~0.004 mm) of millimeter. Silt is the product of physical weathering, such as freezing and thawing.or a rock to be a siltstone, it must be over fifty percent silt-sized material.
