wall rock การใช้

• We big-wall rock climb, big-wave surf, adventure snowboard and underwater hang glide.
• Hanging wall rocks at the Nalunaq Mine are Paleoproterozoic amphibolite-facies metavolcanics.
• It's a balls-to-the-wall rock record, not a slow one like the last one ".
• The Paleoproterozoic recrystallization ) in the batholith with that in the supracrustal wall rocks.
• Stoping occurs when blocks of wall rock material are transferred downward through a pluton.
• The mineralized wall rock mostly, but not exclusively, consists of shale-argillite ( slate ).
• Wall rocks generally contain more sulphides than the veins, in the form of arsenopyrite selvedges.
• Some inclusions in Licancabur rocks seem to be from wall rocks of the magma chamber.
• Pioneering big-wall rock climber Warren Harding is getting ready to climb Yosemite's El Capitan again.
• Gold mineralization at Goldboro occurs in quartz veins and disseminated sulphides in the wall rock.
• It commonly accompanies metasomatism and is often a feature of wall rock alteration around ore bodies.
• Exoskarns occur at and outside the granite which produced them, and are alterations of wall rocks.
• Here, fluids react less via chemical exchange of ions, but because of the redox-oxidation potential of the wall rocks.
• However, the widest use of the word is in describing the metasomatised zones of wall rock adjacent to granites.
• Gravity surveying can be used to detect dense bodies of rocks within host formations of less dense wall rocks.
• In volcanoes, wall rock can often become broken off the wall and incorporated into the erupted volcanic rock as xenoliths.
• Semi-massive sulfides are more common and are composed of 75-90 % Fe-Ni-Cu sulfides with inclusions of olivine and wall rocks.
• Whilst fractional crystallisation is the dominant process, it can be triggered in the magma body by assimilation of the wall rocks.
• Higher temperatures also allow mafic magmas to assimilate wall rocks more readily and therefore contamination is more common and better developed.
• However, slip on low angle normal faults could be facilitated by fluid pressure, as well as by weakness of minerals in wall rocks.
