Ukukuyisa emadwaleni - granite

I-Granite iwuhlobo lwamatshe olusabalele kakhulu endaweni.Yakha inqwaba yoqweqwe lwezwekazi oluguquke kakhulu ngokwezinto zayo zamakhemikhali futhi iwuphawu olubalulekile oluhlukanisa uMhlaba kwamanye amaplanethi.Iphethe izimfihlo zokukhula kwe-continental crust, ukuvela kwe-mantle kanye noqweqwe, kanye nemithombo yamaminerali.

Ngokuya nge-genesis, i-granite iyidwala le-acidic magmatic elingena ngokujulile, elikhiqizwa kakhulu njengesisekelo sedwala noma uhlobo.Akunzima ukuhlukanisa i-granite ngokubukeka kwayo;isici sayo esihlukile ukuphaphatheka kwayo, umbala wayo obomvu kakhulu.Amaminerali amakhulu akha i-granite yi-quartz, i-feldspar ne-mica, ngakho-ke ngokuvamile umbala nokucwebezela kwe-granite kuzohluka kuye ngokuthi i-feldspar, i-mica namaminerali amnyama.Ku-granite, i-quartz yenza i-25-30% yenani eliphelele, inokubukeka kwengilazi encane ene-greasy sheen;I-potassium feldspar yenza ama-40-45% we-feldspar kanye ne-plagioclase engu-20%.Enye yezakhiwo ze-mica ukuthi ingahlukaniswa ngama-flakes amancane ngenaliti eduze kwe-deconstruction.Ngezinye izikhathi i-granite ihambisana namaminerali e-paramorphic afana ne-amphibole, i-pyroxene, i-tourmaline ne-garnet, kodwa lokhu akuvamile noma akutholakali kalula.

Izinzuzo zegwadle zivelele, i-homogeneous, iqinile, imunca amanzi amancane, amandla okucindezela we-rock block angafinyelela ku-117.7 kuya ku-196.1MPa, ngakho-ke kuvame ukubhekwa njengesisekelo esihle sezakhiwo, njengemihosha emithathu, i-Xinfengjiang, I-Longyangxia, i-Tenseitan namanye amadamu aphehla ugesi ngamanzi akhiwe phezu kwegwadle.I-Granite futhi iyitshe lokwakha elihle kakhulu, inobulukhuni obuhle, futhi inamandla amakhulu okucindezela, i-porosity encane, ukumuncwa kwamanzi aphansi, ukuqhutshwa kwe-thermal okusheshayo, ukumelana nokugqokwa okuhle, ukuqina okuphezulu, ukumelana nesithwathwa, ukumelana ne-asidi, ukumelana nokugqwala, akulula ukumelana nesimo sezulu. , ngakho-ke kuvame ukusetshenziselwa ukwakha izinsimbi zebhuloho, izinyathelo, imigwaqo, kodwa futhi nezindlu zamatshe, uthango nokunye.I-Granite ayinamandla futhi iyasebenza kuphela, kodwa futhi inobuso obushelelezi obunama-engeli ahlanzekile, ngakho-ke ivame ukusetshenziselwa ukuhlobisa kwangaphakathi futhi ibhekwa njengetshe lokuhlobisa eliphezulu.

I-Granite ayilona uhlobo olulodwa lwedwala, kodwa inezinhlobonhlobo eziningi, ngayinye yazo ebonisa izici ezihlukene kuye ngezinto exutshwe ngazo.Uma i-granite ixubene ne-orthoclase, ngokuvamile ibonakala i-pink.Amanye ama-granite anombala ompunga noma, lapho eshintshashintsha, aluhlaza okotshani.
