AbstractFractures are pervasive across the nearly flat-lying strata of the autochthonous St. Lawrence Platform of the Anticosti Basin. Satellite imagery of the eastern Mingan islands and eastern Anticosti Island exhibit a principal fracture set trending ~N105 that is often intersected orthogonally by a ~N15 trending fracture set, in agreement with field observations. Lineaments observed on aerial images however are inconsistent with the fractures observed on satellite imagery and are considered a poor reflection of the fracture pattern.
Summary(Plain Language Summary, not published)
Fractures are widespread across the nearly flat-lying strata of the Anticosti Basin. Satellite imagery of the eastern Mingan islands and eastern Anticosti Island exhibit intersecting fracture sets, in agreement with field observations. Lineaments observed on aerial images however are inconsistent with the fractures observed on satellite imagery and are considered a poor reflection of the fracture pattern.
