Rock beds of basins and domes Consider that geologic basins, similar to household bowl basins, have a bowl-like structure. Normal faults a. Dip-slip fault b. Problem solution is in blue color. ABSTRACT The Wills Valley Anticline is located in the … 7.7.1 Fault type: Fault Photo 2 Fig. Fig. In both normal and reverse faults the hanging wall is above the footwall. 1 University of Alabama, P.O. Hanging wall B. Footwall C. Types of faults 1. A prominent hanging wall feature of the southern segment is the Moab Anticline, with a crestal collapse graben accommodated by an array of normal faults. Yukon River near Eagle, Alaska. Reverse faults a. block, add anticline and syncline symbols. This pushes older strata on top of younger strata, upsetting the order of deposition. It is more shallow and the fracture plane tends to curve as the fault reaches deeper … Hanging wall moves down relative to footwall c. Emplaces younger rocks on older rocks d. Tensional stresses e. Extends and thins crust f. Example mid-ocean ridges, western U.S., Basin and Range~100%, East African Rift System 2. This is the redbeds of the latest-Ordovician Juniata Formation. A. Structure of the Wills Valley Anticline, Alabama Delores M. Robinson 1, Marty G. Gates 2, and Andrew M. Goodliffe 1. Use dashed line ... • Note that the anticline has the oldest strata in the core of the structure, and the syncline has the youngest, and note the axial trace symbols for anticline and syncline. Label the hanging wall (HW) and the footwall (FW). The equivalent of … Thrust fault B. 2 U.S. Army Corps of Engineers, 465 Stinson Ridge, Carrollton, Alabama 35447. Thrust Fault - A special kind of reverse fault. 182. Compression experiment in tectonic modeling lab exercise. Thrust direction. Reverse Fault; The hanging wall slides up relative to the other. Imagine the dip of the basin sides from one side to the opposite side. Joints are the most commonly observed structure at the earth's surface. In this oblique view of a sandbox modeling development of structures in a deforming wedge undergoing contraction, an upper wet layer has greater strength. Near and at the earth's surface, rocks break and crack. An anticline in the hanging wall of a thrust fault in the Valley & Ridge. Plunging anticline map view Here is an overhead view of a plunging anticline. Hangingwall anticline structure is a feature associated with: A. Draw half arrows next to the fault to show the sense of motion on the fault and identify the type of fault as normal, reverse, thrust, or strike-slip. Box 870338, Tuscaloosa, Alabama 35487 . To the south in the White Hall quadrangle, Frederick County, Virginia (Figure 7), the hanging wall is made up of an anticline-syncline pair of the Welltown syncline and Pumpkin Ridge anticline, and the footwall is the overturned Mount Pleasant syncline composed of Devonian Mahantango Formation [10, 11]. Hint 3. These ramp-flat sequences are important for petroleum geologists because the hanging wall structures can act as hydrocarbon traps, for both oil and gas. 7.7.2 Sketch the major fault that runs in the NE-SW direction.
