Reverse Fault; The hanging wall slides up relative to the other. Near and at the earth's surface, rocks break and crack. Rock beds of basins and domes Consider that geologic basins, similar to household bowl basins, have a bowl-like structure. Hangingwall anticline structure is a feature associated with: A. In this oblique view of a sandbox modeling development of structures in a deforming wedge undergoing contraction, an upper wet layer has greater strength. Beds dip away from the hinge of the anticline. In both normal and reverse faults the hanging wall is above the footwall. Thrust Fault - A special kind of reverse fault. 2 U.S. Army Corps of Engineers, 465 Stinson Ridge, Carrollton, Alabama 35447. Hanging wall B. Footwall C. Types of faults 1. 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. 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. Structure of the Wills Valley Anticline, Alabama Delores M. Robinson 1, Marty G. Gates 2, and Andrew M. Goodliffe 1. Plunging anticline map view Here is an overhead view of a plunging anticline. The hanging wall slides down relative to the other. Reverse faults a. Problem solution is in blue color. block, add anticline and syncline symbols. Fig. Joints are the most commonly observed structure at the earth's surface. These ramp-flat sequences are important for petroleum geologists because the hanging wall structures can act as hydrocarbon traps, for both oil and gas. Label the hanging wall (HW) and the footwall (FW). Box 870338, Tuscaloosa, Alabama 35487 . 1 University of Alabama, P.O. This is the redbeds of the latest-Ordovician Juniata Formation. 182. Compression experiment in tectonic modeling lab exercise. The equivalent of … 7.7.1 Fault type: Fault Photo 2 Fig. Normal faults a. Dip-slip fault b. 7.7.2 Sketch the major fault that runs in the NE-SW direction. Thrust direction. Imagine the dip of the basin sides from one side to the opposite side. It is more shallow and the fracture plane tends to curve as the fault reaches deeper … Hint 3. Thrust fault B. ABSTRACT The Wills Valley Anticline is located in the … 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. Normal fault C. Strike-slip fault D. Scissor fault … Lynn Fichter for scale. … An anticline in the hanging wall of a thrust fault in the Valley & Ridge. 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. Miners following ... anticline-syncline pair in the core of an ancient mountain system, South ... and pop-up structure. Yukon River near Eagle, Alaska. 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]. A. This pushes older strata on top of younger strata, upsetting the order of deposition. The Moab Anticline is an asymmetric fold with a wavelength of approximately 1 km, an amplitude of 350 m and a length of over 10 km.
