NDEAPI MATHOMBO AKANYORWA AKASIKWA UYE ANOGONA KUSHANDISWA KUPI? landscape stone

Sei vamwe matombo chaiwo achionekwa seakapfava kana ose achiratidzika kuva akaoma? Mhinduro iri mukati mekuoma kwe'relative'. Mohs chiyero chekuomarara chakagadzirwa muna 1812 uye chinofananidza kuomarara kwakaoma kwemaminerari gumi. Dhaimondi ndiro rakanyanya kuoma uye mazinga gumi, nepo giraniti ndiro rakaomesesa dombo rechisikigo pa 6. Limestone inopinda pa 3 sezvinoita mumwe wayo metamorphic, marble. Dombo rakapfava riri nyore kupfeka kana kuveza asi haripfeki kana mamiriro ekunze pamwe chete nedombo rakaomarara. Pano tinokurukura mamwe ematombo akapfava anozivikanwa zvikuru pamwe chete nemashandisirwo akakodzera.

Matombo asina kurongeka

Sedimentary rock

Limestone, sandstone uye shale ndiwo anonyanya kuzivikanwa marudzi e sedimentary rock. Izvi zvakaumbwa kuburikidza nedzvinyiriro huru, pamusoro pemamiriyoni emakore, zvichidzika pasi pevhu rakanga rawira pasi pegungwa.

Slate

Iwo maturu muslate anotsanangurwa se "foliated" uye anopatsanurwa zviri nyore kuti agadzire chero ukobvu hunodiwa. UK slate inoonekwa seyakaoma uye yagara ichishandiswa sedenga, nepo slate yakapfava inowanikwa muChina, Spain, Italy neUSA. Iine huwandu hwakakura hwemavara echisikigo slate, akawanda akawanda madhizaini anogona kuwanikwa, kubva kumazuva ano kusvika kukirasi, rustic kusvika kunatswa. Slate inowanzo kurudzirwa kunzvimbo dzakakwirira dzemotokari, nekuda kwekuumbwa kwayo kusimba. Iyo zvakare isiri-porous uye haiite nyore kuita ine acid zvinwiwa. Icho chiratidzo chemoto, inodzivirira mamiriro ekunze uye inowana yakanaka kutsvedza kuramba nekuda kwekupera kwayo.

Limestone

Limestone chinhu chakajairika chekuvakisa uye chinoumbwa zvakanyanya kubva kune mineral calcite, inotorwa kubva mucalcium mumapfupa nemahoko egungwa akaiswa pamusoro pemireniya uye kumanikidzwa pamwechete kuburikidza nekumanikidzwa. Kunyange iinewo magnesium, yakaoma uye inodzivirira mamiriro ekunze, uye inogona zvakare kukwenenzverwa. Portland ibwe kubva kuchitsuwa chisina zita muDorset ingangove ndiyo yakakurumbira mhando yeraimu uye yakashandiswa kuvaka akawanda ezvivakwa zvikuru zveLondon. Inoshandiswa kupfekedza kunze pamwe nekugadzira, nzvimbo dzemoto uye zvimwe zvemukati nekunze zvekushongedza zvinhu. Mavara ayo akapfava ndiwo hunhu hwayo hwekuona.

Sandstone

Sandstone ingangove ndiro rainyanya kushandiswa dombo rekuvaka risati rasvika 1800, kune zvese kubva kumabhiriji kusvika kune zvivakwa zvakanaka. Sezvingave zvichitaurwa kubva kuzita rayo, inoumbwa apo jecha, organic zvinhu, calcite uye akasiyana emamwe maminerari zvakasanganiswa pamwechete pasi pekumanikidzwa kunoshamisa pamusoro pemireniyamu. Inowanikwa pamwe neyakaomarara kana yakanaka mameseji uye yakajairika inopihwa mukupedzisa matt. Kunyanya kirimu, tsvuku kana grey muUK, ruvara rwayo rwunotsamira pane mamwe mamineral arimo. Silika inopa kuchena, nepo simbi ichapa tsvuku-brown tint. Nzvimbo dzayo huru dzekushandisa madziro uye pasi, kana paving yekunze.

Marble

Marble inotorwa kubva kune limestone, yakaumbwa kuburikidza nemetamorphosis yekupisa kukuru uye kudzvanywa kwemamiriyoni emakore. Kunyangwe zvakapfava zvichienzaniswa nemamwe matombo, marble anowanzo kupururudza zvinoshamisa. Pachinyakare marble inoshandiswa mumasuo uye inobatsira kugadzira kupera kwepamusoro.
