Hauv optical mineralogy thiab petrography, a nyias seem (los yog petrographic nyias seem ) yog ib qho chaw kuaj mob ntawm pob zeb, pob zeb hauv av, av, lauj kaub tais diav, pob txha, lossis txawm tias cov qauv hlau siv nrog lub polarizing petrographic microscope, electron microscope thiab electron microprobe.

Ib yam li ntawd ib tug yuav nug, ua li cas koj ua ib tug nyias seem?

Cov txheej txheem no yog ib qho yooj yim:

  1. Xyuas kom cov seem huv si thiab tsis muaj grit lossis av.
  2. Muab tso rau ntawm lub phaj kub.
  3. Sib tov ib pawg me me ntawm epoxy thiab hardener.
  4. Muab ib qho me me ntawm epoxy tso rau ntawm ntu.
  5. Muab ib daim npog plam ntawm qhov poob.
  6. Txav mus rau ib ncig kom tshem tawm npuas thiab npog tag nrho cov seem.
  7. Cia nws kho.

Kuj Paub, koj tuaj yeem qhia tau li cas yog biotite nyias? Hauv nyias seem , biotite nthuav tawm me ntsis nyem thiab daj ntseg mus rau tob greenish xim av los yog xim av xim, nrog rau nruab nrab mus rau muaj zog pleochroism. Biotite muaj lub siab birefringence uas tuaj yeem npog ib nrab los ntawm nws cov xim sib sib zog nqus.

Yog li ntawd, vim li cas geologists ua cov ntu nyias?

Nyias ntu cia peb saib cov ntxhia hauv ntau yam sib txawv. Qhov no tso cai rau peb pom cov ntxhia pob zeb tshiab thiab pab nrog kev txheeb xyuas cov ntxhia. Nws yog tus nqi qis atomic sojntsuam.

Koj piav qhia txog ntu nyias li cas?
