Sandstone yog cov pob zeb tshaj plaws siv, nws lub zog thiab kev coj tus cwj pwm coj zoo ib puag ncig yam ntxwv ntawm kev ua tiav ntawm lub vaj tsev keeb kwm ntawm lub paj. Pua pua xyoo dhau los, nrog sandstone decorated nrog lub Louvre, lub British imperial Palace, Harvard University, Sandstone Notre Dam De Paris thiab kom deb li deb tseem tseem, refined code ib si.
Lub ntuj zoo nkauj cov nyhuv thiab artistic Sandstone teeb ntawm sandstone nyob rau hauv lub tsev thiab dai qhov chaw yog incomparable nrog rau lwm yam ntaub ntawv zoo nkauj. Kev ntom ntom nti thiab qhov muaj zog thiab zoo, nws tuaj yeem ua kom pom ntau hom kev sib txawv.
Sandstone yog Sandstone tsim los ntawm quartz hais (xuab zeb) thiab yog structurally ruaj khov, feem ntau daj liab lossis liab, tsuas yog muaj silicon, calcium, av nplaum thiab hlau oxides. Sandstone Sandstone yog ib lub pob zeb, uas yog cemented los ntawm cov xuab zeb nplej, nyob rau hauv uas grain cov ntsiab lus ntawm cov xuab zeb yog ntau tshaj li ib nrab. Feem ntau sandstone yog ua los ntawm quartz los yog feldspar. Ntawm no yog ib qho piav qhia ntawm hom sandstone!
Quartz Sandstone: Cov ntsiab lus ntawm quartz thiab siliceous cuttings accounted rau ntau tshaj 95% ntawm tag nrho cov xuab zeb hauv detritus, uas tsuas muaj me me los yog tsis muaj feldspar, cuttings thiab cov minerals hnyav. Cov cua quag yog cov quartz siv lead ua, sib tsoo thiab qhov cais yog qhov zoo dua, Sandstone qhov kev sib sau kom loj hlob thiab kev loj hlob ntawm tus qauv yog qhov siab tshaj plaws. Me me, nyiaj yug me nyuam. Lub quartz lwm yam sandstone yog hu ua thaum lub hauv paus txawv yog 15%. Quartz sandstone yog tsim nyob hauv thaj chaw ruaj khov geotectonic, cov topography yog quasi-dawb, lub pob zeb yog huab cua ntev, cov khoom ntawm denudation yog feem ntau nyob rau hauv qhov chaw ntawm dej hiav txwv (xws li cov dej hiav txwv), uas yog tsim los ntawm lub zog yoj thiab dej ntws thiab qhov qeeb deposition ntawm rov ua dua. Nws yog feem ntau symbiotic nrog carbonate deposits, tsim los ntawm quartz sandstone-hiav txwv-ua carbonate, Sandstone xws li sab qaum sab ntawm North Tuam Tshoj-Taipei-Cambrian.
Feldspar sandstone: feldspar clastic cov ntawv qhia txog ntau tshaj 25% ntawm tag nrho cov xuab zeb hauv qib xuab zeb. Quartz ntsiab lus uas yog 75%, muaj peev xwm muaj ntau cov kua nplaum thiab ntau hom minerals. Cov cement no mas khov thiab hlau, feem ntau muaj cov av nplaum. Thaum twg lub 15 yog tov, nws belongs rau Sandstone lub feldspar complex sandstone. Cov pob zeb clastic claws feem ntau yog muab faib thiab puag ncig nruab nrab. Feldspar sandstone yog feem ntau daj ntseg daj, nqaij hmoov los yog ntsuab tshauv thiab lwm yam xim. Feldspar sandstone tau muab faib ua 3 hom raws li nws cov kev mob, uas yog tectonic feldspar sandstone, qab feldspar sandstone thiab climatic feldspar Sandstone sandstone. Feldspar sandstone yog feem ntau muaj zog tectonic zog hauv cheeb tsam, leej niam pob zeb yog granite los yog granitic gneiss, qhov kev nyab xeeb yog qhuav thiab txias, tsuas yog lub cev huab cua, nyob rau hauv muaj zog erosion thiab ceev tsuj zuj zus ntawm tej yam kev mob. Feem ntau cov qaum teb tuaj, hiav txwv ua rau tsawg dua. Feem ntau tso rau hauv Piedmont los yog nyob rau hauv lub roob phiab. Nws tau raug pom tias ntau feldspar sandstones tau ua nyob rau hauv Continental Rift Valley. Muaj feldspar sandstone nyob rau hauv lub Sinian system ntawm Tangshan, Hebei xeev, nyob rau hauv uas feldspar muaj peev xwm tshaj li 50%.
