Pātai Arowhenua: he aha kohuke e rerekē i toka

E mea pinepine i roto i te tuhinga pūtaiao rongonui i reira ko nga ngā "kohuke" me "toka". Iwi kahore e nei i te mātauranga motuhake, e kore e faaite i enei ariā, kite enei kupu tata rite taurite. Ko te hua'tu he tenei. Kia kite a he aha kohuke e rerekē i te toka.

kohuke

I roto i te tikanga ki te whakamārama i te rerekētanga i waenganui i te kohuke i te kamaka, i te hanganga taiao, whakaaro katoa taipitopito. E ai ki nga whakaritenga o te rōpū mineralogical International ki kohuke ngā totoka i hanga i roto i te ngakau aroha o te whenua ona papa he te hanganga matū taua, me te hanganga, tioata ranei.

Otiia kahore e whakatau rite kohuke katoa te whakamāramatanga. Hei tauira, i reira te tīariari matū he te hanganga matū taua, engari e kore e hanga i karaihe ripekapeka, pera-ka karanga kohuke amorphous (rikuri). Ngota i roto i taua hanganga e tata rawa ki tahi i te tahi, me te kore e hanga i te pūnaha whakahau. Ko te kupu te here i waenganui i ngā ngota kaha nui. Ka taea te whakaritea i te hanganga ki te karaihe.

whakarōpū o ngā kohuke

Scientists tāpeke e pā ana ki 2500 kohuke, e whai ratou ake momo. E ai ki nga mea timatanga matū hanga wahi o, kua wehea kohuke ki te maha ngā rōpū:

• āhuatanga Maori - taonga ripekapeka karaihe e ngā o tetahi anake huānga matū. Hei tauira, he whanariki, koura, konukawata. meka Interesting: taimana me te graphite - kohuke kei roto waro anake, engari he hanganga karaihe rerekē. I roto i tenei take, te taimana - te kara o te kaha me te graphite, i runga i te anga ke, rawa ngohengohe. Tenei rōpū ngā pā ana ki 90 kohuke.
• Sulfides - kohuke e tito o te whanariki me konganuku nonmetals ranei nei tioata. Hei tauira, galena, sphalerite. meka Interesting: Ko te pyrite kohuke kua he ingoa tuarua "koura o wairangi." Ko e tika ana ki te meka e āhua pyrite i te tae me te konganuku whiti rite te whakarewa utu nui tenei. Tenei rōpū ngā pā ana ki 200 kohuke.
• Ngā pūkawa - Mariao tūturu o te waikawa pungatara. Hei tauira, barite, jarosite, gypsum, anhydrite. Interesting meka: barite - anake te kohuke e taea e haamou i te X-hihi. Na reira, nga mata i roto i te ruma X-ray ngā o te kohuke me hipoki nga taiepa e ki barite te raima. Ko te rōpū ngā pā ana ki 260 kohuke.
• Halides - kohuke i hanga e te huinga o ngā huānga matū ki kōnakonako. Hei tauira, fluorite, sylvite, halite. meka Interesting: i te Roma Emperor Nero te ngoikore mo te fluorite, hoko hua i hanga o reira he rota o te moni. Ko te rōpū ngā pā ana ki 100 kohuke.
• Phosphates - tote tūturu o te waikawa phosphoric. Hei tauira, vivianite, papura, apatite. Interesting meka: emerara - Pahi te kōhatu tino tino. Ko te utu o te tahi mau tūemi i roto i 3-4 wa ki runga ake i te utu o te koura. I roto i te rōpū o e pā ana ki 350 kohuke.
• Pākawa waro - tūturu tote o te waikawa carbonic. Hei tauira, konupāhiko, dolomite, magnesite. meka Interesting: i roto i te maunga mekameka māeroero ngā te ngohi, ka karanga te Dolomites, no te mea o te kamaka ngā dolomite. Maunga i raro i te rā tahuri ratou māwhero.
• Waikura - kohuke, i hanga e te pūhui o konganuku me waikura. Hei tauira, Alexander, kiripaka, rikuri. meka Interesting: Ametrine ko tetahi o te onge i roto i te ao. Ko tōna āhuatanga he e he ahurei te ahua o te kohatu utu nui, he rerekē i te tetahi o mua ia tauira hou. He pā ana ki 200 kohuke te rōpū.
• Silicates - te rōpū tino whānui o kohuke e ngā silicon, konumohe. Hei tauira, he topaha, plagioclase, tangiwai. He meka ngā ko e te aroaro o te tenenga te aroaro o te pereti karaihe whakaurua i roto i te matapihi a Mika.

Na, i roto i te tikanga ki te kite i te rerekētanga, me nga wehewehenga o nga toka, me ngā kohuke, whakamārama tatou te ariā o te tuatahi i huaina.

toka

e kore e kohuke kirinuku o te whenua kitea wā taratahi. Ka rite ki te tikanga, i raro i te mana o ngā āhuatanga o waho, ngā ratou ki puka toka. Ko te kupu, e rerekē i te kamaka i te mea te reira te poraka whare wāhi kohuke. Otiia kahore e whai wāhi kohuke katoa i roto i te hanganga o ngā toka. Na reira, wehewehea ratou pūtaiao ki toka-hanga (te nuinga silicates) me āpitihanga.

Whakarōpū o toka

Hoki te atu mārama māramatanga e rerekē i te toka o te mea kohuke, whakamārama tatou te hanganga o te muri. Tohunga pūtaiao wehewehe toru ngā rōpū o toka i runga i te ara o ratou takenga:

• Tokarewa i hanga e te tokarewa effusion i roto i te whenua ranei i nui i runga i te mata (puia). Ko ratou nga momo tuatahi, o nei hua i roto i te rerekē mau mana taiao i hanga momo e rua e toe ana ngā rōpū. Hei tauira, ofa'i, te karā, gabbro.
• Kāhuarau e nekeneke nekehanga o te kirinuku o te whenua. tikanga o tēnei e i ano nga waipara me toka magmatic i roto i te whenua o nui, me te reira i raro i te mana o tiketike pāmahana me te pēhanga puta ki ahu hou. Hei tauira, te kāhuarau kanapa, te schist, mapere.
• Ko te wahi o toka parataiao pūkete mō te% 10 anake. E hanga e ratou kia rite ki te hua o te mahi hau i runga i te magmatites wai tikanga i runga i te mata o te whenua. Hei tauira, eluvium, talus, alluvium.

Ko te hanganga o ngā toka me ngā kohuke - tu'ati roa. whakatau tatou he aha kohuke e rerekē i te kamaka, a he pakari tatou e nehenehe e mea e kōtuitui enei wāhanga o te kirinuku o te whenua.
