    There were two major episodes of igneous activity in northern New England and Quebec during the Mesozoic: a period between 200-155 Ma, and a later period between 130 and 100 Ma. The older activity was centered around central and northern New Hampshire, and was dominated by alkali syenites, quartz syenites, and granites (Eby, 2004).
