Dab tsi yog qhov sib xyaw ntawm cov granites?

ZebYog cov pob zeb tshaj plaws hauv ntiaj teb Continental Continental Continental Crust, nws paub zoo li cov xim liab, dawb, grey, thiab dub ornamental pob zeb. Nws yog coarse- rau nruab nrab-grained. Nws peb lub ntsiab lus tseem ceeb, quartz, thiab mica, uas tshwm sim li Silverycetite lossis tsaus ntuj. Ntawm cov zaub mov no, feldspar predominates, thiab quartz feem ntau cov account rau ntau tshaj 10 feem pua. Cov alkali Feldspars feem ntau yog liab, ua rau muaj paj yeeb granite feem ntau siv ua pob zeb zoo nkauj. Granite crystallizes los ntawm Silica-nplua nuj Magmas uas tau mais tob hauv lub ntiaj teb crust. Ntau daim ntawv tso nyiaj ntawm cov ntxhia pob zeb nyob ze crystallizing granite lub cev los ntawm cov kev daws teeb meem hydrothermal uas cov cev tso tawm.

Kev sib faib

Nyob rau hauv lub sab sauv ntawm Qapf kev faib tawm ntawm PLutonic pob zeb (Q 20%) thiab 65 A) piv txwv: Sysenogranite thiab Monzogranite. Tsuas yog pob zeb ua pob zeb projecting nyob rau hauv lub sarseegranite yog suav tias yog granites nyob rau hauv lub eleglo-saxon ntawv nyeem. Nyob rau hauv cov ntaub ntawv nyob hauv European, pob zeb projecting kev tsis pub dhau ob qho tib si sylogranite thiab monzogranite yog cov npe granites. Lub Monzogranite sub-teb muaj adamellite thiab quartz monzonite hauv cov laus classifications. Kev yuam kev rau cov pob zeb cassification cov lus pom zoo tshaj plaws yog qhov tsis ntev los no lub sij hawm plawg siab thiab mus rau cov pob zeb projecting nyob rau hauv quartz monzonite teb sensu stricto.

Tshuaj Muaj Tshuaj

Ib tug thoob ntiaj teb nruab nrab ntawm cov tshuaj lom neeg muaj pes tsawg leeg ntawm granite, los ntawm qhov hnyav feem pua,

Raws li 2485 tshuaj xyuas:

• Sio2 72.04% (silica)
• AL2O3 14.42% (Alumina)
• K2O 4.12%
• Nai-3.69%
• CAO 1.82%
• Feo 1.68%
• Fe2O3 1.22%
• Mgo 0.71%
• Ti2 0.30%
• P2O5 0.12%
• MNO 0.05%

Nws ib txwm muaj cov zaub mov quartz thiab feldspar, nrog lossis tsis muaj ntau yam meterals (cov khoom siv khoom siv ntxiv). Lub quartz thiab feldspar feem ntau muab cov xim granite, xws li los ntawm pinkish kom dawb. Lub teeb tom qab muaj teeb liab yog punctuated los ntawm cov minery tsaus nti. Yog li Classic Granite muaj "ntsev-Andpepper" saib. Feem ntau cov khoom siv tau muab cov txiv hmab txiv ntoo yog cov dub fica biotite thiab dub amphibole hornbende. Yuav luag txhua cov pob zeb no tsis ua haujlwm tsis zoo (nws muaj kev lom zem los ntawm cov tawv nqaij magma) thiab plutonic (nws tau ua li ntawd nyob rau hauv lub cev loj, mob siab rau lub cev lossis pluton). Cov kev npaj random hauv granite- nws tsis muaj ntaub npuag-yog cov pov thawj ntawm nws lub keeb kwm PLutonic. Pob zeb nrog tib yam sib xyaw ua ke ua granite tuaj yeem tsim los ntawm kev ntev thiab kev sib cav ntawm cov metamorphism ntawm cov pob zeb sedimentary. Tab sis hais tias hom pob zeb ntawd muaj cov ntaub muaj zog thiab feem ntau hu ua granite gneiss.

Qwj + melting point

Qhov ntsuas nruab nrab ceev ntawm nws yog nruab nrab ntawm 2.65 thiab 2.75 g / cm 3, thiab nws cov viscosity nyob ze stp yog 3-6 s ·. Melting kub yog 1215-1260 ° C. Nws muaj tsis muaj kev tso cai thawj kav tab sis muaj zog thib ob permeability.

Qhov tshwm sim ntawm pob zeb granite

Nws pom nyob hauv cov pluaj loj loj rau ntawm cov teb chaws, hauv cov cheeb tsam uas lub ntiaj teb txoj kev ua kaub puab tau mob siab heev. Qhov no ua rau kev nkag siab, vim tias granite yuav tsum solorify qeeb ntawm tob tob qhov chaw los ua cov pob zeb loj. Plutons me dua 100 square kilometers hauv thaj chaw hu ua cov khoom lag luam, thiab cov loj dua yog hu ua batholiths. Lavas tawg thoob plaws lub ntiaj teb, tab sis qava nrog tib txoj kev muaj pes tsawg leeg ua granite (rhyolite) tsuas yog tawg rau cov teb chaws. Qhov ntawd txhais tau tias Granite yuav tsum ua los ntawm melting ntawm continental pob zeb. Qhov ntawd tshwm sim rau ob qho laj thawj: ntxiv cov cua sov thiab ntxiv cov khoom tawg (dej lossis roj carbon dioxide lossis ob qho tib si). Cov teb chaws feem ntau yog kub vim tias lawv muaj feem ntau ntawm cov ntiaj chaw uranium thiab potassium, uas ua rau lawv ib puag ncig los ntawm kev sib luag. Txhua qhov chaw uas CRUST yog thickened nyees kom tau kub sab hauv (piv txwv li ntawm Tibetan Plateau). Thiab cov txheej txheem ntawm phaj tectonics, feem ntau yog kev sib luag, tuaj yeem ua rau basaltic magmas kom sawv hauv qab teb chaws. Ntxiv rau cov cua sov, cov Micymas tso Co2 thiab dej, uas pab pob zeb ntawm txhua yam melt ntawm qis dua kub. Nws yog kev xav tias cov basaltic magma yuav plastered rau hauv qab ntawm ib sab av loj hauv ib tus txheej txheem hu ua underplating. Nrog qeeb tso tawm thaum tshav kub kub thiab kua los ntawm cov basalt, muaj ntau ntawm cov crust xwb yuav tig mus rau granite tib lub sijhawm.

Nws pom qhov twg?

Txog tam sim no, nws tau paub tias nws tau pom hauv lub ntiaj teb tsuas yog muaj ntau npaum li hauv txhua qhov chaw ua ib feem ntawm Continental Crust. Cov pob zeb no tau pom hauv me me, Tshuag-zoo li cov pawg me me tsawg dua 100 km², lossis hauv batholiths uas yog ib feem ntawm orogenic mountain. Ua ke nrog rau lwm cov av loj thiab sedimentary pob zeb, feem ntau ua cov hauv paus av nqes hav. Nws tseem muaj nyob hauv cov lacolites, trenches thiab thresholds. Xws li nyob rau hauv lub granite muaj pes tsawg leeg, lwm yam pob zeb hloov yog alpids thiab pegmatites. Cov nplaum nrog Finer particle me dua li tshwm sim ntawm cov ciaj ciam ntawm granitic kev tawm tsam. Pangular Pegmatites ntau dua GRANITE feem ntau qhia cov granite tso nyiaj.

Granite siv

• Cov neeg Iyiv thaum ub ua lub pyramids los ntawm granites thiab limestones.
• Lwm yam siv hauv Egypt thaum ub yog txhua qhov chaw, lub qhov rooj lints, sills, mouldings, moulds thiab phab ntsa npog.
• Rajaraja chola lub chola dynasty nyob rau hauv South Is Nrias teb, nyob rau hauv lub nroog 11th nyob rau hauv lub nroog Tanjore nyob rau hauv Is Nrias teb Granite. Tus neeg hloov kho lub tuam tsev, mob siab rau tus Tswv Shiva, tau tsim hauv 1010.
• Nyob rau hauv lub tebchaws Roman, Granite tau dhau los ua ib qho tseem ceeb ntawm cov khoom siv tsev thiab monumental architectural lus.
• Nws yog feem ntau siv ua pob zeb loj. Nws yog raws li kev puas tsuaj, tau muaj lub pob zeb muaj txiaj ntsig vim nws cov qauv uas lees txais qhov nyuaj thiab ci thiab txhuam tau pom tseeb.
• Nws yog siv rau hauv cov chaw sab hauv rau polished granite slabs, vuas, cov pobzeb, cov stair treads thiab ntau lwm yam kev ua tau zoo thiab cov nta.

Niaj hnub

• Siv rau pem teb lub hom phiaj.
• Engineers muaj kev coj ua ib txwm siv cov phaj polished granite los tsim lub dav hlau vim tias lawv kuj tsis yooj yim

Ntau Lawm Granite

Nws yog mined thoob ntiaj teb tab sis feem ntau cov xim sib txawv yog muab tau los ntawm granite tso rau hauv Brazil, Is Nrias teb, Finland, South Africa thiab North America. Cov pob zeb mining yog ib qho peev thiab cov txheej txheem ua haujlwm. Cov pob zeb granite raug muab tshem tawm los ntawm kev tso nyiaj los ntawm kev txiav lossis tshuaj tsuag. Cov hlais tshwj xeeb yog siv txiav cov pob zeb-extracted rau hauv cov phaj portable, uas yog tom qab ntawd ntim thiab thauj los ntawm kev tsheb nqaj hlau lossis kev xa khoom. Tuam Tshoj, Brazil thiab Is Nrias teb yog cov thawj coj granite hauv ntiaj teb.
