Evidence for post-Acadian through Alleghanian deformation in eastern Maine: multiple brittle reactivation of the Norumbega Fault system
Please note that Figure 6 of Wang and Ludman, published in Atlantic Geology, Volume 38, No. 1, page 44, was printed with insufficent contrast. The figure and caption are reproduced here.
Figure 6
Fig. 6 (a) and (b) are photographs of faulted rocks breccia (a) and cataclasite (b) generated by episode 1 brittle faulting in the Flume Ridge metasedimentary rocks in the Waite fault zone. (a) is at south side of Fourth Machias Lake and (b) southern Nicatous Lake. (c) shows near-horizontal slickenlines shown on episode 1 conjugate fault surfaces in Amazon Mountain granite, Grand Lake Stream. (d) shows episode 1 conjugate faults in metasedimentary rocks, Kellyland Dam. Big arrows indicate inferred maximum principal stress orientations. All are plan view.
