Summary:

Red Beach Granite underlies 40 percent of area defined as quadrilateral with corners at Coleback Lake, Nashs Lake, Devils Head, and Mills Cove on the St. Croix River, eastern ME. Unit is composite of six distinct intrusions. Medium and coarse-grained biotite granite members are tentatively correlated with the Charlotte Granite. Fine-grained biotite granite and hornblende granophyre members are older than the Charlotte. Other members not discussed. Intrudes Eastport Formation and unconformably underlies Perry Formation. Age is Early Devonian.
