A dike los yog ua dyke , nyob rau hauv geological siv, yog ib daim ntawv ntawm pob zeb uas yog tsim nyob rau hauv ib tug tawg ntawm ib tug pre-existing pob zeb lub cev. Magmatic dikes daim ntawv thaum magma ntws mus rau hauv ib qho tawg ces solidifies raws li ib daim ntawv intrusion, yog txiav hla txheej ntawm pob zeb los yog los ntawm ib tug continuous loj ntawm pob zeb.

Cov neeg kuj nug, ua li cas yog cov dike?

Dikes tuaj yeem yog magmatic lossis sedimentary hauv keeb kwm. Magmatic dikes daim ntawv thaum magma intrudes mus rau hauv ib tug tawg ces crystallizes raws li ib daim ntawv intrusion, txiav hla cov khaubncaws sab nraud povtseg ntawm pob zeb los yog los ntawm ib tug unlayered loj ntawm pob zeb. Clastic dikes yog tsim thaum sediment puv ib qho kev tawg ua ntej.

Qhov thib ob, qhov twg tuaj yeem nrhiav pom? Sedimentary Dikes Lawv feem ntau yog pom nyob rau hauv lwm chav tsev sedimentary, tab sis ua tau kuj tsim nyob rau hauv ib tug igneous los yog metamorphic loj. Clastic dikes tau daim ntawv nyob rau hauv ob peb txoj kev: Los ntawm fracturing thiab liquefaction txuam nrog av qeeg.

Yog li ntawd, lub dike zoo li cas?

Ib geological dike yog lub cev tiaj tus ntawm pob zeb uas hla lwm hom pob zeb. Dikes txiav hla lwm hom pob zeb ntawm ib lub kaum sab xis sib txawv dua li lwm cov qauv. Dikes feem ntau pom tau vim tias lawv nyob ntawm lub kaum sab xis sib txawv, thiab feem ntau muaj xim sib txawv thiab kev ntxhib los mos dua li pob zeb nyob ib puag ncig lawv.

Dab tsi yog dikes thiab sills?

Hauv geology, a sill yog ib daim ntawv tabular intrusion uas tau intruded ntawm cov laus txheej ntawm sedimentary pob zeb, txaj ntawm volcanic lava los yog tuff, los yog raws li cov kev taw qhia ntawm foliation nyob rau hauv metamorphic pob zeb. Piv txwv li, a dike yog ib daim ntawv tsis sib haum xeeb, uas txiav hla cov pob zeb qub.
