footwall การใช้

• The hanging wall moves downward, relative to the footwall.
• The footwall is also much more extensively hydrothermally altered than in continental settings.
• The Mons Cupri rhyolite is in the footwall and shows typical silica-chlorite alteration.
• Footwall rocks are volcanogenic massive sulfides.
• Footwall drainage is limited in the Gulf of Evvia while transfer zone drainage is more pronounced.
• It develops locally over individual fault blocks because of footwall uplift and lithospheric unloading by extension.
• The felsic footwall is subject to a pronounced stretching lineation which increases in intensity to the north.
• This is interpreted to occur due to competency contrast between the felsic footwall and the ultramafic unit.
• By definition, the hanging wall occurs above the fault plane and the footwall occurs below the fault.
• The unloading of the footwall can lead to isostatic uplift and doming of the more ductile material beneath.
• A reverse fault is the opposite of a normal fault the hanging wall moves up relative to the footwall.
• They are characterized by long domes parallel to the spreading direction ( oceanic core complexes of the footwall ).
• It can often be reasonably strained throughout its bulk and especially in the footwall contact with the Widgiemooltha Komatiite.
• The new added layers are thicker within the footwall than within the hanging wall ( fig . 2 ).
• Seismic line showing sedimentary layers, footwall and hanging wall of a growth fault : Modified after Bjerkvik, 2012
• The footwall gneiss contains anomalous mineral chemistries including a rare lead-rich feldspar and manganese-rich garnet chemistries.
• The mining operations were consolidated in the Copper vein area and the most productive headings in the " Footwall Area ".
• The fault surface is usually near vertical and the footwall moves either left or right or laterally with very little vertical motion.
• As this section of crust cools it tends to subside causing the footwall of the fault to tilt down toward the west.
• Also, having been sunk into the footwall, longer and longer cross-cuts were needed to reach the vein from it.
