Granite, sechinhu chinoshandiswa zvakanyanya mukuvaka, kushongedzwa, mabhesi ezviridzwa zvega uye mamwe minda, density yayo chiratidzo chakakosha chekuyera kunaka uye kuita. Pakusarudza zvigadzirwa zvegranite, zvakakosha kuti unzwisise izvo zvakakosha zvinokanganisa density yavo. Zvinotevera zvichakutsanangura zvakadzama kwauri.
I. Mineral Composition
Granite inonyanya kuumbwa nemaminerari akadai sequartz, feldspar uye mica. Chimiro chekristaro, zvirimo uye mhando yezvicherwa izvi zvese zvine chekuita nekuwanda. Iwo makristasi zvimiro zvequartz nefeldspar zvine compact, uye density yavo yakakwira. Kana zviri mukati memaminerari maviri aya mugranite zvakakwirira, huwandu hwese huchawedzerawo zvinoenderana. Semuenzaniso, mamwe marudzi egranite akapfuma muquartz uye feldspar anowanzo kuve nehukuru hwakanyanya. Pane zvinopesana, chimiro chekristaro chemica chakasununguka. Kana iyo mica yemukati mugranite yakakwira zvakanyanya, zvinotungamira mukudzikira kwayo. Pamusoro pezvo, granite ine mamwe maminerari ane huremu hwemamorekuru hwakanyanya senge iron uye magnesium kazhinji ine huremu hwepamusoro. Granite, iyo yakapfuma mune silicate minerals, ine dhizaini yakaderera.
Ii. Particle Saizi uye Chimiro
Chikamu saizi
Iyo yakanyanya kunaka iyo granite particles ndeye, iyo yakasimba iyo inotutira, uye mashoma emukati voids aripo, izvo zvinotungamirira kuwedzera kwehuwandu hwehuwandu hwehuwandu hwehuwandu uye huwandu hwepamusoro. Sezvineiwo, kune coarse-grained granite, zvimedu zvinonetsa kurongedzerwa pamwe chete uye kune akawanda ma voids, zvichikonzera kuderera kwakati.
Dhigirii yekusimba kwechimiro
Granite ine compact dhizaini ine zvicherwa zvimedu zvinosanganisirwa zvakanyanya neasina pachena voids. Ichi chimiro chinobatsira kuwedzera density. Nekudaro, iyo yakasununguka yakarongeka granite, nekuda kwekusangana kwakasununguka pakati pezvimedu, ine nzvimbo yakakura uye yakasikwa ine density yakaderera. Semuyenzaniso, granite ine dense chimiro chakaumbwa kuburikidza neakakosha maitiro e geological ine density yakasiyana zvakanyanya kana ichienzaniswa neyayo yakasununguka-yakarongeka yakaenzana.
Iii. Dhigirii reCrystallization
Munguva yekuumbwa kwegranite, sezvo tembiricha uye kudzvanywa zvichichinja, mineral makristasi anozopenya zvishoma nezvishoma. Granite ine yakakwira dhigirii yekristaro ine kurongeka uye compact crystal kurongeka, uye maburi ari pakati pemakristasi madiki. Naizvozvo, ine hukuru hukuru pavhoriyamu yevhoriyamu uye ine density yakakwira. Granite ine yakaderera dhigirii recrystallization ine yakawedzera kusagadzikana kristaro kurongeka uye mikaha mikuru pakati pemakristasi, zvichikonzera kuderera kwakati.
Iv. Pores uye Cracks
Munguva yekuumbwa uye kucherwa kwegranite, pores uye kuputika kunogona kuitika. Kuvepo kweaya ma voids kunoreva kuti hapana chakasimba chekuzadza zvinhu muchikamu ichi, izvo zvinozodzikisa huwandu hwese hwegranite uye nekudaro kudzikisa density yayo. Iyo yakawanda pores uye makatsemuka aripo, iyo yakakura saizi yavo uye yakafara kugovera kwavo, zvakanyanya kujeka mhedzisiro yekuderedza density ichave. Naizvozvo, pakusarudza zvigadzirwa zvegranite, kucherechedza kana paine pachena pores uye makatsemuka pamusoro payo anogona kushandiswa sechinhu chinongedzo chekuongorora kuwanda kwayo.
V. Kuumba Mhoteredzo
Yakasiyana geological mamiriro ezvakatipoteredza anogona kutungamira kune mutsauko mukugovera uye zvirimo zvezvicherwa mugranite, nekudaro zvichikanganisa density yayo. Semuyenzaniso, granite inoumbwa pasi pekupisa kwepamusoro-tembiricha uye yakanyanya-kudzvanywa mamiriro ine yakazara yakazara mineral crystallization, yakawedzera compact chimiro, uye inogona kunge yakakwira density. Density yegranite inoumbwa munzvimbo ine hunyoro inogona kusiyana. Uye zvakare, zvakatipoteredza zvakaita setembiricha, kudzvanywa uye hunyoro zvinogona zvakare kukanganisa chimiro uye mineral kuumbwa kwegranite, zvisina kunanga kukanganisa density yayo.
Vi. Maitiro ekugadzirisa
Nzira dzinoshandiswa mukuchera migodhi, dzakaita sekuputika kwemigodhi, dzinogona kukonzera kutsemuka kudiki mukati megranite, zvichikanganisa kutendeseka kwayo uye zvichizove nekukanganisa kusimba kwayo. Iyo yekupwanya, kukuya uye dzimwe nzira panguva yekugadziriswa inogona zvakare kushandura iyo particle mamiriro uye chimiro chegranite, nekudaro ichikanganisa density yayo. Panguva yekufambisa nekuchengetedza, nzira dzisina kurongeka dzekurongedza kana nzvimbo dzakaomarara dzekuchengetera dzinogona kuita kuti granite idzvinyirwe, kudhumhana kana kukukurwa, izvo zvinogona kukanganisa kuwanda kwayo.
Mukupedzisa, pakusarudza zvigadzirwa zvegranite, zvinodikanwa kuti utarise zvakadzama zvinhu zvakasiyana-siyana zvinokanganisa density zvataurwa pamusoro apa kuti unyatso ongorora maitiro avo uye usarudze yakanyatsokodzera zvinhu zvegranite kune chaiwo mashandisirwo mamiriro.
