Danielle NihiserFaults, Folds, and Fractures Lab1. Golden Gate Canyona. There are 3 different fracture sets located in the rock. b. Dip: 50˚ WSW 2ndSet Dip: 80˚ N3rdSet- Dip: 70˚ENEStrike: 350˚ NNWStrike: NEStrike: 350˚ NNWc. The face that was facing towards us is the most dominant set because the entire face was displayed.d. Open fractures- allowing more cracking in the rocks, and permitting water to enter fractures and increasing mechanical weatheringRedox: the outer most layer is more reddishe. Looking at an aerial photo, fracture sets are identified by linear vegetation growth, large zones of fracturing and distinct layers in the rock beds. 2. I-70 Roadcuta. Strike: 350˚ NNWDip: 25˚ Eb. Oldest units are to the west of where we are standing.c. The type of folding is an anticline because the older rock is on the outside. d. The shale crumbles and the sandstone severely fractures because shale experienced more of the stress when folding occurred. e. Moving to the west, the rock is going to fracture more due to increased stress from
