Tus naj npawb ntawm ntuj pob txha muab faib los ntawm qhov ntev thiab qhia raws li pob txha ib ko taw pob txha ib meter. Pob zeb Kev Tsim Nyog Zoo (RQD) [2] yog a tawg index siv nyob rau hauv ntau pob zeb kev faib systems.
Ntawm no, koj yuav suav li cas Rqd ntawm pob zeb?
Pob zeb Lub Npe Zoo ( RQD ) yog qhov hloov pauv tseem ceeb rov qab feem pua ntawm qhov ntev ntawm txhua lub suab pob zeb core pieces tshaj 100 mm nyob rau hauv ntev yog summed thiab muab faib los ntawm qhov ntev ntawm cov tub ntxhais khiav.
Tsis tas li ntawd, tag nrho cov tseem ceeb rov qab yog dab tsi? Txhais. Cov tag nrho cov tub ntxhais rov qab (TCR) txhais tau tias yog feem ntawm core zoo mus rau tag nrho ntev ntawm qhov drilled khiav. Cov tub ntxhais khiav yog qhov ntev qhia los ntawm driller raws li qhov tseeb qhov tob tob.
Tib neeg kuj nug, dab tsi yog pob zeb cores?
Pob zeb Cores . Pob zeb cores muab ib tug loj "plug" ntawm pob zeb rau kev ntsuam xyuas, thiab cia cov roj av geologists tau txais kev saib zoo dua ntawm qhov pob zeb tob hauv ib qhov dej. Lawv muaj txiaj ntsig ntau dua li cov me me drilling chips hu ua cov qauv zoo, lossis pob zeb cuttings, uas yog retrieved thaum lub sij hawm drilling.
Rqd rock mechanics yog dab tsi?
Pob zeb - kev xaiv zoo ( RQD ) yog ib qho kev ntsuas ntxhib ntawm qhov sib koom ua ke lossis tawg hauv a pob zeb huab hwm coj, ntsuas raws li feem pua ntawm cov tub ntxhais xyaum hauv qhov ntev ntawm 10 cm lossis ntau dua. Siab zoo pob zeb muaj ib RQD ntawm ntau tshaj 75%, tsis zoo ntawm tsawg dua 50%. Pob zeb kev xaiv zoo ( RQD ) muaj ntau lub ntsiab lus.

Dab tsi yog qhov txawv ntawm cov pob zeb tsis foliated thiab foliated metamorphic pob zeb?
Foliated metamorphic pob zeb xws li gneiss, phyllite, schist, thiab slate muaj ib txheej txheej los yog banded zoo li uas yog tsim los ntawm raug tshav kub thiab qhia siab. Non-foliated metamorphic pob zeb xws li hornfels, marble, quartzite, thiab novaculite tsis muaj txheej txheej lossis banded zoo li
Nyob rau hauv hom pob zeb twg koj yuav pom fossils Vim li cas?
Sedimentary pob zeb, tsis zoo li igneous thiab metamorphic pob zeb, yog tsim los ntawm gradual deposition thiab cementation ntawm cov khoom nyob rau hauv lub sij hawm. Cov pob zeb zoo li no muab cov xwm txheej zoo tshaj plaws rau pob txha pob txha vim tias cov nroj tsuag thiab cov tsiaj seem tuaj yeem npog los ntawm txheej txheej ntawm cov ntaub ntawv dhau sijhawm, yam tsis muaj kev puas tsuaj
Koj puas tuaj yeem muab cov pob zeb tso rau hauv pob zeb tumbler?
Feem ntau hom pob zeb tsis ua haujlwm zoo hauv pob zeb tumbler. Yog tias koj sib tov zoo tumbling ntxhib nrog pob zeb uas qis dua qib qis, cov khoom, cov npoo ntse thiab tawg ntawm cov khoom hauv qab-tumbling-qib tej zaum yuav ua rau cov polish ntawm txhua lub pob zeb hauv lub thoob
Yuav ua li cas lub pob zeb sedimentary ua ib lub pob zeb metamorphic?
Sedimentary pob zeb ua metamorphic nyob rau hauv lub pob zeb voj voog thaum lawv raug tshav kub thiab siab los ntawm faus. Cov kub kub yog tsim thaum lub ntiaj teb daim hlau tectonic txav ib ncig, ua kom sov. Thiab thaum lawv sib tsoo, lawv tsim roob thiab metamorphose
Lub npe rau lub pob zeb nruab nrab ntawm cov pob zeb uas txias heev yog dab tsi?
Extrusive igneous pob zeb
