Are the only differences between a laccolith and a batholith their sizes?

Thanks for reading.|||No, they are smaller in size but they also differ in shape. A laccolith is a sill that bulges upward so they look like a dome. Sills are concordant bodies, meaning that they do not cut across layers in the bedrock. A batholith is generally steep walled and batholiths cut across the original bedrock. Here are a couple of sites that explain laccoliths and batholiths

http://en.wikipedia.org/wiki/Batholith|||Laccolith has a diameter of up to 8km with a thickness of a few meters to a few hundred meters with a flat floor and a CONVEX upper surface.


A batholith has a surface area of greater then 100km2 and can be made of MULTIPLE plutons
