The stratified rocks include the volcanic, sedimentary and metamorphic rock types. Intrusive rocks include the granites, gabbros and ultramafic rocks that are frequently seen cropping out along eastern coastal Maine..
In respect to this, what kind of rocks are in Maine?
All three major rock groups - sedimentary, igneous, and metamorphic - are represented in Maine. Here is an abbreviated list of Maine rock types. Sedimentary rocks: shale, mudstone, siltstone, various sandstones, arkose, graywacke, chert, limestone, conglomerate.

Accordingly, why is the Maine coast so rocky?
Glacial erosion accentuated the weaker layers in this group producing the long, narrow bays. Farther north (north of Penobscot Bay) the coast exposes numerous irregular granitic bodies and hard volcanic rocks. Here too, glacial erosion has accentuated the underlying structure.
