Siltstone is not classified as either an extrusive or intrusive rock; those terms apply to igneous rocks. Siltstone is a type of sedimentary rock formed from the compaction and cementation of silt-sized particles. It typically forms in environments like riverbeds, lakes, or marine settings where fine sediments accumulate.

Is limestone a intrusive igneous rock?
No, limestone is a sedimentary rock that forms from the accumulation of mineral particles such as calcite or aragonite. Intrusive igneous rocks are formed from the cooling and solidification of magma beneath the Earth's surface.
Is gray slate intrusive or extrusive?
Gray slate is an example of a metamorphic rock, not an igneous rock, so the terms intrusive and extrusive do not apply to it in the same way. Slate forms from the metamorphism of shale under heat and pressure, causing the original sedimentary layers to recrystallize and align. Intrusive rocks crystallize slowly beneath the Earth's surface, while extrusive rocks form from lava that cools quickly on the surface. Therefore, gray slate is neither intrusive nor extrusive.
