  BSE pictures of meteorites
Images de météorites au MEB
© Meteoriteshow

Les images ci-dessous ont été réalisées à l'aide d'une sonde electronique equipé d'un dispositif MEB.
Voir la première image pour l'échelle et la taille des analyses, qui sont valables pour toutes les suivantes.

Pictures hereafter have been otained thanks to an electronique probe (SEM), fitted with a BSE device.
First picture gives the scale and analyses size, which are valid for all.

Tanezrouft 069 :
H5

Chondrules are almost invisible, proving a high metamorphism.
Fe/Ni flakes appear white (heavier material

 

 

 

Picture #1 : Laboratoire de Sciences de la Terre. UCB -Lyon. ENS-Lyon 

 

Tanezrouft 068 :
H4/5

Chondrules can be seen with their boundaries darker, and their crystal structure.
Fe/Ni flakes appear white (heavier material) and thin ones can be seen even inside of chondrules

 

 

 

Picture #2 : Laboratoire de Sciences de la Terre. UCB -Lyon. ENS-Lyon 

 

Tanezrouft 068 :
H4/5

A big chondrule can be seen in the centre, with its crystal structure very sharp.
Fe/Ni flakes appear white (heavier material)

 

 

 

 

 

Picture #3 : Laboratoire de Sciences de la Terre. UCB -Lyon. ENS-Lyon 
 

 Tanezrouft 068 :
H4/5

Rests of chondrules quite metamorphised can be seen, almost without any boundary visible.
Fe/Ni flakes appear white (heavier material)

 

 

 

 

Picture #4 : Laboratoire de Sciences de la Terre. UCB -Lyon. ENS-Lyon

 

Tanezrouft 068 :
H4/5

Chondrules can be seen with their boundaries darker, and their crystal structure.
Fe/Ni flakes appear white (heavier material) and thin ones can be seen even inside of chondrules

 

 

 

Picture #5 : Laboratoire de Sciences de la Terre. UCB -Lyon. ENS-Lyon 

 

Tanezrouft 068 :
H4/5

More chondrules contain Fe/Ni flakes in the area covered by this picture.

 

 

 

 

 

Picture #6 : Laboratoire de Sciences de la Terre. UCB -Lyon. ENS-Lyon 

 

Tanezrouft 070 :
L6

Chondrule boundaries are almost invisible, proving quite a high metamorphism.
Fe/Ni flakes appear white (heavier material)

 

 

 

 

Picture #7 : Laboratoire de Sciences de la Terre. UCB -Lyon. ENS-Lyon

 

Tanezrouft 071 :
L5

Rests of chondrules can be seen but their boundaries are not very sharp.
Fe/Ni flakes appear white (heavier material)

 

 

 

 

Picture #8 : Laboratoire de Sciences de la Terre. UCB -Lyon. ENS-Lyon

 

Tanezrouft 071 :
L5

Rests of chondrules can be seen but their boundaries are not very sharp, except for two of them on the left.
Fe/Ni flakes appear white (heavier material)

 

 

 

Picture #9 : Laboratoire de Sciences de la Terre. UCB -Lyon. ENS-Lyon

 

Tanezrouft 071 :
L5

Chondrules are sharper in this area.
Fe/Ni flakes appear white (heavier material)

 

 

 

 

Picture #10 : Laboratoire de Sciences de la Terre. UCB -Lyon. ENS-Lyon 

 

Tanezrouft 071 :
L5

A magnificent crossed chondrule can be seen on the top left corner. Others are not that sharp.
Fe/Ni flakes appear white (heavier material)

 

 

 

 

Picture #11 : Laboratoire de Sciences de la Terre. UCB -Lyon. ENS-Lyon 

 

Tanezrouft 071 :
L5

A huge chondrule can be seen in the center, surrounded by Fe/Ni flakes, which appear white (heavier material)
