Suevite and impact breccias with heavily shocked biotite-plagioclase and amphibolite fragments, glass bombs.
Shock pressure: 16-20 GPa.
Rutile is associated with two other TiO2 polymorphs :
- TiO2 (alpha-PbO2 structure)
- monoclinic TiO2 (akaogiite, with baddeleyite-type structure)

Detailed Mineral List:

Coesite
Formula: SiO2
Reference: http://geosciences.smsu.edu/geology/FieldTrips/Ries/page5.html
Cristobalite
Formula: SiO2
Reference: http://geosciences.smsu.edu/geology/FieldTrips/Ries/page5.html
Diamond
Formula: C
Description: Impact diamonds in glass bombs and gneiss elemnts of the suevite. Diamonds appear as thin pseudo-hexagonal plates (up to 100 µm) : they have formed by displacive phase transformation in solid state (martensitic or diffusion process) from graphite.

Graphite
Formula: C
Description: Residual in diamonds.

Hematite
Formula: Fe2O3
Reference: http://geosciences.smsu.edu/geology/FieldTrips/Ries/page5.html
Ilmenite
Formula: Fe2+TiO3

'Moldavite'
Reference: http://www.museum.hu-berlin.de/min/mitarbeiter/mitarb/ralf/diamante.html
Rutile
Formula: TiO2
Description: Rutile is associated with two other TiO2 polymorphs : - TiO2 (alpha-PbO2 structure) with pink internal reflections - TiO2 (Baddeleyite structure P21/c) with intense blue internal reflections and reflectivity much higher than rutile TiO2 with ZrO2 structure forms fine-grained polycrystalline monophase grains surrounded by shock-twinned ilmenite and rutile, or single grains rimmed by rutile, alpha-PbO2 TiO2, ilmenite and titanite.
Reference: A. El Goresy et al. , Science, Vol. 293, 24 August 2001, pp. 1467-1470.
Titanite
Formula: CaTi(SiO4)O
Reference: A. El Goresy et al. , Science, Vol. 293, 24 August 2001, pp. 1467-1470.
