Exercise chapter 1/ Label the parts of a trap indicated in figure below 2/ What is the difference between gross pay and net pay, and why is it important? Give a example to clarify 3/ Construct a cross section through a compactional anticline Hint: Use a horst-and-graben basal layer 4/ There are some important differences between compactional and compressional fold traps Below is a listing of 12 features, each pertaining to only one of the two fold types Please fill in the appropriate title _ folds form contemporaneously with sedimentation and initial burial _ folds commonly form in one major tectonic event _ folds sometimes have secondary porosity (diagenetic) developed on their crests, due to leaching and subaerial exposure _ folds sometimes have secondary porosity which is fracture-related _ folds are often irregularly shaped due to shape of underlying features _ folds may have a lengthy history due to rejuvenation of underlying basement faults _ folds are usually lithified before deformation, so the rocks are brittle _ folds have their primary porosity often preserved throughout _ folds contain sediments which deform soon after deposition, while still soft _ folds are generally oriented with their long axis perpendicular to direction of crustal shortening _ folds sometimes have primary porosity which may vary between crest and flank _ folds usually form long after sedimentation and initial burial
