M'madera ambiri padziko lapansi, ndizotheka kumanga ndi miyala yachilengedwe. Zomwe zimapangidwira mwala wachilengedwe zimasiyana mosiyanasiyana malinga ndi kuchuluka kwa miyala; pali mwala woyenera wachilengedwe pafupifupi zofunikira zonse zomangira. Sichikhoza kuyaka ndipo sichifuna kulowetsedwa, kapena zokutira kapena zoteteza. Miyalayo ndi yokongola ndipo iliyonse ndi yapadera. Chifukwa cha mitundu yosiyanasiyana, mapangidwe ndi malo, omanga nthawi zonse amakhala ovuta kupanga chisankho. Chifukwa chake, zoyambira zosiyanitsa, njira yachitukuko, mawonekedwe akuthupi, zitsanzo zamagwiritsidwe ntchito ndi kusiyanasiyana kwamapangidwe ziyenera kumveka.
Mwala wachilengedwe umagawidwa m'magulu atatu kutengera zaka zake komanso momwe unapangidwira:
1. Magmatic rock :
Mwachitsanzo, granite ndi thanthwe lolimba lomwe limapanga magulu akale kwambiri a miyala yachilengedwe, yomwe imakhala ndi chiphalaphala chamadzimadzi, ndi zina zotero. Miyala yamoto imaonedwa kuti ndi yolimba komanso yowonjezereka. Mwala wakale kwambiri womwe umapezeka mu meteorites mpaka pano unapangidwa zaka 4.53 biliyoni zapitazo.
2. Zidole, monga miyala yamchere ndi mchenga (yotchedwanso sedimentary rocks):
Anachokera mu nyengo yaposachedwapa ya nthaka, yopangidwa kuchokera ku matope pamtunda kapena m'madzi. Miyala ya Sedimentary ndi yofewa kwambiri kuposa miyala yoyaka. Komabe, miyala ya miyala yamchere ku China idayambanso zaka 600 miliyoni zapitazo.
3. Miyala ya metamorphic, monga slate kapena marble.
Zimaphatikizapo mitundu ya miyala yopangidwa ndi miyala ya sedimentary yomwe yasintha. Mitundu ya miyala iyi ndi ya m'badwo waposachedwa kwambiri wa geological. Slate idapangidwa zaka 3.5 mpaka 400 miliyoni zapitazo.
Marble ndi thanthwe la metamorphic lopangidwa ndi mchere wopangidwanso ndi mchere wa carbonate, womwe nthawi zambiri umatchedwa calcite kapena dolomite. Marble amagwiritsidwa ntchito nthawi zambiri muzosema ndi zomangira. Marble amakopa chidwi cha ogula ndi mawonekedwe awo okongola komanso mawonekedwe ake othandiza. Mosiyana ndi miyala ina yomangira, mawonekedwe a nsangalabwi iliyonse amasiyana. Ndi mawonekedwe owoneka bwino komanso opindika ndi osalala, osakhwima, owala komanso atsopano, omwe amakubweretserani phwando lowoneka bwino pazogwiritsa ntchito zosiyanasiyana. Zofewa, zokongola, zowoneka bwino komanso zokongola m'mapangidwe, ndizoyenera kukongoletsa nyumba zapamwamba, komanso chikhalidwe chazojambula zojambulajambula.
Pambuyo pa chaka cha 2000, migodi ya nsangalabwi yogwira ntchito kwambiri inali ku Asia. Makamaka makampani achilengedwe a nsangalabwi aku China adakula mwachangu kuyambira pomwe adasintha ndikutsegulira. Malinga ndi mtundu woyamba wa opukutidwa pamwamba, nsangalabwi opangidwa ku China akhoza zili pafupifupi magawidwe asanu mndandanda: woyera, wachikasu, wobiriwira, imvi, wofiira, khofi ndi black.China ndi wolemera kwambiri mu nsangalabwi mchere chuma, ndi nkhokwe zazikulu ndi mitundu yambiri. , ndipo nkhokwe zake zonse zili m'gulu lapamwamba kwambiri padziko lonse lapansi. Malinga ndi ziwerengero zosakwanira, pali mitundu pafupifupi 400 ya nsangalabwi yaku China yomwe yafufuzidwa mpaka pano.
Monga imodzi mwamakampani oyamba odziwika bwino ku China Natural Mable, Ice stone ndi imodzi mwazinthu zazikulu komanso akatswiri opanga miyala yamwala yaku China ku Shuitou. Tikugwira ntchito molimbika kuti tiyimire China Marble ndikubweretsa dziko la China marble wapamwamba kwambiri monga momwe "Made in China".
