GEOL 3032 : Some Sedimentology Notes For Exam 1
Document Summary
Formations in the fundy group, components of the newark. Contacts are conformable if they are characterized by unbroken depositional assemblages, deposited in generally parallel superposition. Angular unconformity: younger sediments rest upon the eroded surface of older tilted or folded rocks. Disconformity: contact between parallel older and younger sediments marked by irregular or uneven erosional surface. Paraconformity: obscure unconformity with no obious physical evidence for a major hiatus, perhaps only a bedding plane. Nonconformity: contact between sedimentary rock and older, eroded metamorphic or igneous rocks. Sedimentary facies: the aspect, appearance, and characteristics of a rock, usually reflecting the conditions of its origin. (usually reflects the depositional environment) Walthers law of succession of facies: only those facies that can be superimposed (or stacked immediately on top of one another) which can be observed beside each other at the present time. Correlation: act of comparing and connecting statigraphic data sets from outcrop or drill core records on the basis of: lithology,
