Guidebook For Field Trips In Southwestern Maine PDF Download

Excerpt from Guidebook to Field Trips in Southern Maine: 5th Annual Meeting, October 8-10, 1965, at Bowdoin College, Brunswick, Maine The major folds in the quadrangle are the Harpswell Sound syncline on the we st and the Hen Cove anticline on the east. Drag folds with axial plane schistosity are common, especially in the Cape Elizabeth Formation, and in general bear out the major structures. Locally a second set of crude small scale folds involving both bedding and schistosity is developed. Plunges of the primary drags are rather variable indicating frequent reversals of the major plunge direction. Lineations are well-developed in all units of the quadrangle, but especially so in the Cape Elizabeth Formation. In this unit three lineations can commonly be seen. On the bedding surfaces of the competent beds a lineation formed by the intersection of a fracture cleavage and bedding, parallel to the plunge direction of primary fold axes, is frequently present and gives these beds a rather woody appearance. The second and third lineations are observed in the micaceous beds and are formed by the close crenulation of schistosity. The principal crenulation has axes plunging consistently to the northeast about 25 to 30 The lesser crenulation plunges essentially down dip of the general schistosity.
