Meelo badan oo adduunka ah, waxaa suurtagal ah in lagu dhiso dhagax dabiici ah oo deegaanka ah. Tilmaamaha jireed ee dhagaxa dabiiciga ah way kala duwan yihiin iyadoo lagu saleynayo tirada noocyada dhagaxyada; waxaa jira dhagax dabiici ah oo ku habboon ku dhawaad dhammaan shuruudaha qalabka dhismaha. Ma aha mid guban karta oo uma baahna impregnation, ama dahaar ama dahaar ilaalin ah. Dhagaxyada ayaa si qurux badan u roon mid walbana waa mid gaar ah. Sababo la xiriira midabo kala duwan, dhismayaal iyo dusha sare, naqshadeeyayaasha ayaa had iyo jeer ku adag inay go'aan gaaraan. Sidaa darteed, sifooyinka aasaasiga ah ee soocidda, habka horumarinta, sifooyinka jireed, tusaalooyinka codsiga iyo kala duwanaanta naqshadeynta waa in la fahmo.
Dhagaxa dabeeciga ah waxa loo qaybiyaa saddex qaybood iyadoo loo eegayo da’diisa iyo sida loo sameeyay.
1. Dhagaxa Magma-tic:
Tusaale ahaan, granite waa dhagax adag oo sameeya kooxaha dhagaxyada dabiiciga ah ee ugu da'da weyn, oo ka kooban lava dareere ah, iwm. Dhagaxyada igneous ayaa loo tixgeliyaa gaar ahaan adag oo cufan. granite-ka ugu da'da weyn ee laga helay meteorites ilaa taariikhda la sameeyay 4.53 bilyan sano ka hor.
2. Sediments, sida nuuradda iyo dhagaxa ciid (sidoo kale loo yaqaan dhagaxyada sedimentary):
Waxay ka soo jeedaan waayihii ugu dambeeyay ee juquraafiga, oo ka samaysmay qulqulo dhulka ama biyaha ah. Dhagaxyada sedimentary aad bay uga jilicsan yihiin dhagaxyada hurda. Si kastaba ha noqotee, kaydka dhagaxa limestone ee Shiinaha ayaa sidoo kale dib ugu soo laabanaya 600 milyan oo sano ka hor.
3. Dhagaxyada Metamorphic, sida marmar ama marmar.
Waxaa ku jira noocyada dhagxaanta ee ka kooban dhagaxyada sedimentary ee soo maray habka isbeddelka. Noocyada dhagaxyadan ayaa ah da'dii ugu dambaysay ee juquraafiga. Slate wuxuu sameeyay qiyaastii 3.5 ilaa 400 milyan oo sano ka hor.
Marble waa dhagax metamorphic ah oo ka kooban macdan karbonateed oo dib loo soo celiyay, inta badan calcite ama dolomite. Juquraafiga, ereyga marmar waxa loola jeedaa nuurad metamorphic, laakiin isticmaalkeeda suufka si ballaaran waxaa ka mid ah nuurad aan la beddelin. Marble inta badan waxaa loo isticmaalaa farshaxanimada iyo qalabka dhismaha. Marble waxay soo jiidataa dareenka macaamiisha muuqaalkooda quruxda badan iyo sifooyin wax ku ool ah. Si ka duwan dhagaxyada kale ee dhismaha, qaabka marmar kasta waa ka duwan yahay. Iyada oo muuqaal cad oo qaloocan waa siman, jilicsan, dhalaalaya oo cusub, kaas oo kuu keenaya iid muuqaal ah oo loogu talagalay codsiyada kala duwan. Jilicsan, qurux badan, xarrago leh oo xarrago leh, waa qalab ku habboon qurxinta dhismayaasha raaxada, iyo sidoo kale qalab dhaqameed oo loogu talagalay farshaxan farshaxan.
Sannadkii 2000 ka dib, macdanta marmar ee ugu firfircoon waxay ahayd Aasiya. Gaar ahaan warshadaha marmarka dabiiciga ah ee Shiinaha ayaa si degdeg ah u horumaray tan iyo dib-u-habaynta iyo furitaanka. Sida laga soo xigtay midabka aasaasiga ah ee dusha sare, marmarka laga soo saaro Shiinaha ayaa qiyaas ahaan loo qaybin karaa todoba taxane: cad, jaalle, cagaar, cawl, casaan, qaxwo iyo madow , iyo wadarta kaydkeedu waxa uu ka mid yahay kuwa ugu sarreeya adduunka. Marka loo eego tirakoob aan dhameystirneyn, waxaa jira ku dhawaad 400 oo nooc oo marmar Shiinees ah oo la sahamiyay ilaa hadda.
Sida mid ka mid ah shirkaddii ugu horreysay ee ku takhasustay Mable-ka Dabiiciga ah ee Shiinaha, Dhagax barafka waa mid ka mid ah soo saaraha marmarka dabiiciga ah ee Shiinaha ugu weyn ee Shuitou. Waxaan si daacad ah ugu shaqeyneynaa si aan u matalo Shiinaha Marble oo aan keeno adduunka tayada sare ee marmar Shiinaha sida isbeddelka "Made in China".
