Foot wall

Folia commonly exhibit internal banding. Most foliar bands, like the foot-wall-mammillary-calcite bands described earlier, are accumulations of sHt- and clay-sized detritus that settled on top of the folia during growth. Too-rapid sediment accumulation on the actively growing rhombohedral crystal surfaces disrupts crystal growth. Large numbers of very small seed crystals on top of the sediment accumulations (Fig. 12) mark the resumption of calcite precipitation. 

With the exception of well 7125/1-1, group GUI fractures are restricted to the master fault complexes which are known to be characterised by inversion. Well 7125/1-1 is situated in the foot-wall of the Nys-leppen Fault Complex, and it may be speculated as to whether the abundance of low-angle fractures in this well implies that inversion also took place at the northwestern margin of the Nordkapp Basin. 

As the eight monitoring sites all locate in the hanging wall and the foot wall of FI, their seepage situations are crucial for studying the hydraulic connection between the orefield and the Quaternary water-rich phreatic aquifer, and seawater. While the results make clear that the upper drifts have not severe connection with the Quaternary water-rich phreatic aquifer and seawater. It reflects, at present, the water-resistant layers haven t been disturbed seriously by the excavation.

In the mining area, when a steep fault outcropped at the tensional section of the excavated slope, namely, the upper segment of the excavated slope, the fault reactivation usually results in a downward movement on the hanging wall relative to the foot-wall. In this case, a single fault reactivation produces a fault scarp, whereas a group of parallel... 

The initial excavation of the penstocks was made using Alimak electric raise climbers to drive an 8 ft by 10 ft pilot raise on the penstock foot-wall. Each raise was cut without the use of intermediate stations. 

Fig. 12. [Reproduced in colour in Plate 22 on page 436.] (A) The facies model captures implicitly discontinuities related to faults as shown with the distribution of texture-based seismic facies in three dimensions within the hanging wall and foot wall of a fault. The voxel grid geometry defined for the reservoir model is superimposed on the facies model to show how the facies will be associated to the voxels. The facies being located in the centre of the voxel is used to define the property of the cell. (B) Distribution of the facies within the voxel grid geometry.
