Granite - zog. Properties thiab cov kev siv ntawm granite

Ntawm cov tag nrho cov teeb ntawm pob zeb nyob rau hauv lub ntiaj teb yog lub ntsiab pab pawg neeg ntawm magma, uas raug tsim tshaj lab xyoo nyob rau hauv lub thickness ntawm cov kaub puab ntawm lava. Cov pob zeb muaj thiab ib tug ntawm cov loj tsev cov ntaub ntawv - granite. Cov khoom ntawm lub pob zeb tau ntev tau kawm nyob rau hauv tib neeg. Qhov no coj mus rau lub fact tias nws yog dav siv nyob rau hauv kev tsim kho nyob rau hauv lub dhau los lawm, thov nws tam sim no. Ib tug lossis loj tus naj npawb ntawm ancient monuments thiab cov vaj tse fwm rau peb lub sij hawm vim hais tias lawv tau ua los ntawm granite. Nws cim muaj pes tsawg leeg, zoo nkauj grain qauv thiab pab tau cov khoom ua pob zeb no yog heev nrov tsev ntaub.

granite deposits

Tsim lub pob zeb no raws li ib tug tshwm sim ntawm solidification ntawm magma ntawm zoo depths. Raug rau nws muaj lub siab kub, siab nce ntawm cov kaub puab thickness ntawm gases thiab vapors. Nyob rau hauv tus ntawm cov yam tseem ceeb thiab tau txais no cov cim qauv, cov kev ua si ntawm lub teeb thiab duab ntxoov ntxoo uas peb pom nyob rau hauv cov pob zeb no. Feem ntau cov feem ntau nws yog ib grey nyob rau hauv cov xim, tab sis tej zaum kuj extract liab los yog ntsuab granite. Nws cov khoom nyob ntawm seb qhov loj ntawm lub constituent nplej. Nws yog ntxhib , Medium-grained thiab zoo-grained (feem ntau check).

Nta lub pob zeb no yog feem ntau nyob rau hauv sib sib zog nqus dej, tab sis tej zaum nws los txog rau ntawm qhov chaw. Granite deposits muaj nyob rau tag nrho cov continents thiab nyob rau hauv yuav luag tag nrho cov teb chaws, tiam sis feem ntau ntawm lawv nyob rau hauv Siberia, Karelia, Finland, Is Nrias teb, thiab Brazil. Extraction ntawm nws es kim, raws li nws tshwm sim nyob rau hauv daim ntawv ntawm cov loj loj reservoirs, feem ntau extending rau ob peb kis lus mev.

Muaj pes tsawg leeg ntawm pob zeb

Nws yog hais txog polymineral granite pob zeb, tsim los ntawm ob peb yam. Feem ntau ntawm tag nrho cov nws muaj xws li Feldspar, uas txiav txim nws cov xim. Yuav luag ib tug peb lub hlis twg yuav siv sij hawm quartz, uas yog lub xam ntawm ib tug translucent xiavlus nplej. Granite kuj muaj lwm yam minerals (e.g., mus rau 10%, tej zaum nws yuav tsum yog ib tug tourmaline, 20% mica), thiab inclusions ntawm hlau, manganese, monazite los yog ilmenite.

Cov yooj yim zog ntawm granite

Qhov zoo ntawm cov pob zeb no thiab tam sim no cia peb los qhuas cov architectural lug ua tawm ntawm nws nyob rau hauv antiquity. Yuav ua li cas yog lub thaj chaw ntawm granite ua nws thoob plaws siv?

1. Durability. Fine-grained granite ntau ntau yam uas qhia thawj cov cim qhia ntawm kev coj tsuas yog tom qab 500 xyoo. Yog li ntawd, nws hu tej zaum ua nyob mus ib txhis lub pob zeb.

2. Durability. Granite yog lub feem ntau check cov ntaub ntawv uas tom qab pob zeb diamond. Nws yog resistant rau compression thiab tsis sib haum xeeb. Qhov no yog vim quartz zog muaj nyob rau hauv nws cov muaj pes tsawg leeg. Nyob rau hauv tas li ntawd, nws yuav ntshiab yog vim li cas no ib yam tsiaj yog li ntawd muaj zog, thaum koj nrhiav cov lus teb rau lo lus nug ntawm yog dab tsi lub ceev ntawm granite. Nws yog ua tau heev - yuav luag peb tonnes ib cubic Meter.

3. Huab cua kuj. Granite mas kub los ntawm Rho tawm 60 mus rau ntxiv rau 50 degrees Celsius. Qhov no yog qho tseem ceeb heev nyob rau hauv cov huab cua txias. Kev tshawb fawb tau muaj pov thawj hais tias granite khoom tsis poob lawv lub zog tom qab ib tug tib 300-freezing thiab yaj.

4. Waterproof. Nws yog ua tsaug rau cov cuab yeej no, qhov no granite te. Yog li ntawd, nws yog zoo tagnrho rau meem hauv lub embankments.

5. Environmental purity. Granite yog tsis tej thiab yog vim li kev ruaj ntseg rau tej kev tsim kho ua hauj lwm.

6. hluav taws. Qhov no cov ntaub ntawv uas pib rau yaj tsuas yog nyob rau 700-800 degrees Centigrade. Yog li ntawd oblitsevat lawv lub tsev - tsis yog tsuas yog zoo nkauj, tab sis kuj muaj kev nyab xeeb.

7. Yooj Yim ntawm tuav, compatibility nrog rau tej tsev ntaub ntawv, thiab cov richness ntawm textures thiab xim ua rau nws zoo tagnrho rau sab hauv tsim.

8. Kuj mus acids thiab fungi.

granite ua

Txawm tias lub dag lub zog thiab kev kub ceev cov pob zeb, lub pob zeb yog yooj yim ua. Nws zoo nkauj yooj yim mus hlais thiab polish. Feem ntau muag muaj loj granite blocks, slabs los yog granite chippings thiab rubble. Vim hais tias nws yuav ua rau cov vuas, txee thiab cov pob zeb blocks. Lub richness ntawm textures uas ua rau kev siv ntawm ntuj pob zeb granite haum rau tej sab hauv kho kom zoo nkauj. Nws zoo zoo nyoos pob zeb, zoo absorbs lub teeb. Polished rau perfection, nws qhia tau hais tias nws lub meej mom thiab kev zoo nkauj ntawm mica inclusions. Thaum ua txoj kev pob zeb spalling tau nyem qauv nrog zoo nkauj nyhuv ntawm lub teeb thiab ntxoov ntxoo ntawm qhov kev ua si. Thiab ib co hom gray granite tom qab thaum tshav kub kub kho mob yuav ntais dawb.

hom Granites

Raws li minerals yog muaj nyob rau hauv lub muaj pes tsawg leeg ntawm granite, tshwj xeeb tshaj yog yuav tsum xyuam xim rau tsaus ntuj nti-dawb lias Cheebtsam. Cov pob zeb raug muab faib ua ob peb pab neeg: cov Alaska leykogranit, biotite, pyroxene, thiab lwm yam alkaline. Txawv cov ntaub ntawv yog cov pob zeb thiab cov qauv:

- granite porphyry, uas muaj elongated inclusions minerals;

- pegmatoid - sib txawv niaj hnub grain loj ntawm quartz thiab Feldspar ;

- gneiss - ib tug nplua-grained pob zeb;

- Finnish granite, uas tsis hu ua rapakivi muaj ib puag ncig liab blotches;

- sau - ib tug heev interesting ntau yam, nws Feldspar hais cov txheej txheem ntawm nyob rau hauv ib tug npoo zoo li tus ib daim hlab, zoo ib yam li cov neeg thaum ub sau tseg.

Tsis ntev los no nws pib mus rau siv dag granite, tsim los ntawm firing av nplaum minerals. Nws hu ua ib tug granite pob zeb thiab yog yuav luag sib npaug zos rau lub ntuj lub zog.

Cov ntaub ntawv xim pob zeb

Properties thiab cov kev siv ntawm granite kuj yog nyob ntawm seb nws cov xim. Nyob rau qhov no vim qhov txawv ob peb pob zeb pawg:

- amazonite granite vim yog ib feem ntawm lub ntsuab Feldspar muaj ib tug xiav-ntsuab coloring;

- liab thiab xim liab thiab liab leznikovsky - lub feem ntau check;

- heev gray pob zeb, thiab cov npe ntawm lawv cov uas lawv tau txais los ntawm lub ntau lawm chaw: korninsky, Sophia, zhezhelevsky;

- tsawg yog cov dawb granite. Qhov no muaj xws li hom xim los ntawm daj ntseg ntsuab mus rau ib tug pearly grey.

Kev siv ntawm granite

Lub pob zeb no yog rau ntau centuries siv nyob rau hauv kev tsim kho thiab txojkev tej hauj lwm. Qhov no yog vim lub fact tias nws zoo ntau ntau yam pib los cev qhuav dej tsuas yog tom qab 500 xyoo. Nws yog resistant mus rau ntau yam influences, thiab yog heev ruaj. Cov yooj yim zog ntawm granite ua rau nws tau siv nws dav nyob rau hauv kev tsim kho. Qhov twg cov mineral yog siv:
