Small intrusions parallel to existing rock

WebbA sill is a concordant intrusion that runs parallel to the sedimentary layers in the country rock. They are formed when magma exploits a weakness between these layers, shouldering them apart and squeezing between them. As with dikes, sills are younger than the surrounding layers and may be radioactively dated to study the age of sedimentary … WebbBecause their crystals are of the rough equal size, these rocks are said to be equigranular. Intrusive rocks formed at greater depths are called plutonic or abyssal. Some intrusive …
