Reverse Faults Reverse faults form when the footwall moves down relative to the hanging wall along the fault plane. 

If a rock is sufficiently stressed, the yield point will eventually be reached. If a brittle failure is initiated a plane of failure will develop which we describe as a fault. Figure 5.6 shows the terminology used to describe normal, reverse and wrench faults. 

ETA breaks down an accident iato its contributing equipment failures and human errors (70). The method therefore is a reverse-thinking technique, ie, the analyst begias with an accident or undesirable event that is to be avoided and identifies the immediate cause of that event. Each of the immediate causes is examined ia turn until the analyst has identified the basic causes of each event. The fault tree is a diagram that displays the logical iaterrelationships between these basic causes and the accident. 

A directional G/F relay basically is a power-measuring device, and is operated by the residual voltage of the system in conjunction with the residual current detected by the three CTs used for non-directional protection, as shown in Figure 21.19. To provide directional protection, therefore, a residual VT is also essential, in addition to the three residual CTs. The voltage phasor is used as a reference to establish the relative displacement of the fault current. In healthy conditions, i.e. when the current flows in the right direction. = 0. (refer to. Section 15.4.3 for details), and the relay remains inoperative. The relay operates only when the current flows in the reverse direction. 

Using de Morgan s theorem (Table 2.1-1), the fault tree in Figure 3.4.4-9 is converted into the success tree shown in Figure 3.4.4-10. Notice that the effect of the theorem is to reverse tlie logic "AND" gates become "OR" gates and vice versa failure becomes success and vice versa. 

Reverse faulting—h2ts c3. y dominated by compression forces and, therefore, the hanging wall is moved up relative to the footwall. The reverse fault that dips at 30° or less becomes a thrust fault. 

There are two questions that needed to be answered here. (1) How can the ligand access the interiors of big prismatic particles to lead to the smaller particles and (2) Why do the ligands lead to smaller particles at all While it is difficult to conclusively find answers to both the questions, the first step in the digestive ripening procedure offers some leads. (1) The big prismatic particles obtained by the reverse micelle-based synthesis are loaded with defects such as twinning boundaries and stacking faults.

Event trees are used to perform postrelease frequency analysis. Event trees are pictorial representations of logic models or truth tables. Their foundation is based on logic theory. The frequency of n outcomes is defined as the product of the initiating event frequency and all succeeding conditional event probabilities leading to that outcome. The process is similar to fault tree analysis, but in reverse. 

The Tisdale rocks were deformed by two tectonic events that resulted in superposition of east-west isoclinal folds on older north-south open folds. Five camp- to regional-scale faults, including the Hollinger Shear Zone (HSZ), have offset all these rocks. The HSZ is a reverse fault ( 140 m offset) that passes through the Hollinger-Mcintyre mine, strikes 57°, dips 65°S, extends to a depth of >1,500m and formed synchronous with the east-west folds. Most gold mineralization in the HMC deposit is associated with rocks in and above the HSZ. 

Unconformity-related U deposits account for more than 33% of the world uranium resource due to their tremendous grade and tonnage. Most of them occur in the McArthur Basin (Northern Territory, Australia) and in the Athabasca Basin (Saskatchewan, Canada). The ore is commonly found close to the interface between Archaean to lower Proterozoic metamorphic and plutonic rocks, and unconformably overlying Proterozoic sandstones. Basement-rooted graphitic reverse faults are also important structural controls. 

Early Paleoproterozoic metasedimentary/ Archean granitoid basement rocks of the Wollaston Domain. The deposit is also spatially associated with a post-Athabasca Group reverse fault (known as the P2 fault), a feature that occurs within and sub-parallel to a group of graphite-bearing Early Paleoproterozoic metasedimentary units.
