H-related impact-melt rock |
| Location: |
Sahara, Northwest Africa |
| Date of find: |
2004 |
| Tkw: |
11 g + one paired mass of 45 g |
| Specimen weight: |
3.124 g |
| Description: |
Slice, polished, 29 x 23 x 2.2 mm |
| Seperate entry from the Meteoritical Bulletin: |
History: A single stone of 11 g was found 2004 by an anonymous finder in the North African Saharan desert. Petrography: (A. Greshake, MNB) The stone is composed of small, mostly euhedral olivines (Fa6.1–23.9) embedded into a glassy groundmass. Most olivines show a pronounced compositional zoning with Mg-rich cores and Fe-rich rims or vice versa. Small spherical Fe,Ni sulfides are often found in the groundmass and Fe,Ni metal is present. Chondrules were not observed.
Geochemistry: Oxygen isotopes: (I. Franchi and R. C. Greenwood, OU) δ17O = +3.088, δ18O = +4.898, ∆17O = +0.541 (all ‰).
Classification: Ordinary chondrite (H-related impact-melt rock) with shock-related crystallized impact melt, W0/1.
Specimens: A 2.5 g type specimen and one polished thin section are on deposit at MNB. Stefan Ralew of Germany holds the main mass. |

| Type: |
L-related, impact-melt rock |
| Location: |
Sahara, Northwest Africa |
| Date of find: |
2003 |
| Tkw: |
1000 g |
| Specimen weight: |
53.789 g |
| Description: |
Slice, polished, 70 x 68 x 4 mm |
| Seperate entry from the Meteoritical Bulletin: |
History: An anonymous finder recovered several stones weighing 1000 g in total within the North African Sahara in 2003.
Petrography: (A. Greshake, MNB) Shows both Fe,Ni metal-poor and Fe,Ni metal-rich lithologies that both consist of small olivines, pyroxenes, and opaque phases embedded into a glassy Si,Al-rich groundmass. Ca-rich pyroxenes are rare. Olivine (Fa12.9–23.9) and pyroxene (Fs11.2–19.7Wo1.1–2.7) are often compositionally zoned and sometimes pyroxene is overgrown by olivine. No chondrules are observed.
Geochemistry: Oxygen isotopes: (I. Franchi and R. C. Greenwood, OU) Metal-poor lithology: δ17O = +3.24, δ18O = +4.095, ∆17O = +1.106 (all ‰). Metal-rich lithology: δ17O = +3.452, δ18O = +4.505, ∆17O = +1.109 (all ‰).Classification: Ordinary chondrite (L-related, impact-melt rock); shock-related crystallized impact melt, W1/2.
Specimens: A 22.7 g type specimen and one polished thin section are on deposit at MNB. Stefan Ralew of Germany holds the main mass.

Unique lunar meteorite
NWA 4898
Chladni`s Heirs release NWA 4898 for sale - a truly unique and unpaired Moon rock, a so far unknown type of Lunar Basalt, the youngest ever found. Chemistry, texture and an age of only 3.578Ga set NWA 4898 apart from all Apollo samples and all other lunaites. Representing an un-sampled mantle source, NWA 4898 will be subject to further research. Limited supply.
