TheGranite
Granite nasa ne na dutsen wuta, wanda aka samu ta hanyar fashewar magma na karkashin kasa da mamayewar sanyaya crystallization da metamorphic duwatsu na granite. Tare da bayyane crystal tsarin da rubutu. Ya ƙunshi feldspar (yawanci potassium feldspar da oligoclase) da ma'adini, haɗuwa da ƙananan mica (black mica ko fari mica) da ma'adanai masu ma'adinai, irin su: zircon, apatite, magnetite, ilmenite, sphene da sauransu. Babban bangaren granite shine silica, wanda abun ciki shine kusan 65% - 85%. Abubuwan sinadaran granite suna da rauni da acidic. Yawancin lokaci, granite yana da ɗan fari ko launin toka, kuma saboda lu'ulu'u masu duhu, bayyanar yana da speckled, kuma ƙari na potassium feldspar ya sa ya zama ja ko nama. Granite kafa ta magmatic a hankali sanyaya crystallization, binne zurfi a ƙarƙashin saman duniya, lokacin da ba a saba jinkirin sanyaya kudi, zai samar da wani sosai m texture na granite, aka sani da crystalline granite. Granite da sauran duwatsun lu'ulu'u sune tushen farantin nahiyoyi, wanda kuma shine dutsen kutsawa da aka fi sani da shi a saman duniya.
Ko da yake ana la'akari da granite da kayan narkewa ko magma mai banƙyama, amma akwai shaidu da yawa da ke nuna cewa samuwar wasu granite shine samfurin nakasar gida ko dutsen da ya gabata, ba ta hanyar ruwa ko narke tsari da sake tsarawa da sake sakewa ba. Nauyin granite yana tsakanin 2.63 da 2.75, kuma ƙarfin ƙarfinsa shine 1,050 ~ 14,000 kg/sq cm (15,000 ~ 20, 000 fam a kowace murabba'in inch). Domin granite ya fi ƙarfin yashi, farar ƙasa da marmara, yana da wuyar cirewa. Saboda yanayi na musamman da ingantaccen tsarin sifofin granite, yana da kaddarorin masu zuwa:

(7) granite yana da karye kuma an rasa wani yanki ne kawai bayan lalacewa, wanda baya tasiri ga duka.
(8) Abubuwan sinadarai na granite suna da ƙarfi kuma ba su da sauƙin yanayi, wanda zai iya tsayayya da acid, alkali da lalata gas. Abubuwan sinadarai nasa suna daidai da abun ciki na silicon dioxide, kuma rayuwar sabis ɗin na iya zama kusan shekaru 200.
(9) granite yana da filin maganadisu mara aiki, mara amfani da filin barga.
Yawancin lokaci, granite ya kasu kashi uku daban-daban:
Fine granites: matsakaicin diamita na feldspar crystal shine 1/16 zuwa 1/8 na inch.
Matsakaicin granite mai hatsi: matsakaicin diamita na kristal feldspar shine kusan 1/4 na inch.
Ƙananan granites: matsakaicin diamita na feldspar crystal yana da kusan 1/2 inch da mafi girma diamita, wasu har zuwa 'yan santimita. Girman ƙananan granites yana da ƙananan ƙananan.
A cikin 'yan shekarun nan, granite yana da kashi 83 cikin 100 na kayan dutse da ake amfani da su a ginin gine-gine da kashi 17 na marmara.

Marmara yana samuwa ne daga duwatsu masu ƙayatarwa da duwatsu masu rarrafe, kuma dutsen metamorphic ne da aka kafa bayan sake dawo da dutsen farar ƙasa, yawanci tare da nau'in ragowar halittu. Babban bangaren shine calcium carbonate, abun ciki wanda shine kusan 50-75%, wanda shine raunin alkaline. Wasu marmara sun ƙunshi wani adadin siliki dioxide, wasu ba su ƙunshi silica ba. Filayen saman gabaɗaya sun fi rashin daidaituwa kuma suna da ƙananan tauri. Abubuwan da ke cikin marmara yana da kaddarorin masu zuwa:
