Bird Brain,
Hypabyssal dykes and sills crystallize/cool/harden at shallow depths under conditions intermediate between plutonic and volcanic....at depths between .5 and perhaps 3 kilometers.....at these shallow depths, the ambient temperature of the country rock will facilitate rapid cooling of a thin dyke or sill.....perhaps try to do some reading before you start chirping and leaving bird droppings all over this thread....
