Tenham (meteorite)

They are examples of chondritic meteorites, containing a high level of organic compounds, and rich in silicates, oxides, and sulfides.

[1] Because the Tenham meteorites show evidence of high pressure deformations, they have been used to infer chemical and mineral changes that might occur within Earth's mantle.

[2] Ringwoodite, the high pressure forsterite polymorph named after Ted Ringwood, was discovered in fragments of the Tenham meteorite.

[3] In 2014, a team of scientists at Argonne National Laboratory studied a sample of bridgmanite, a silicate perovskite ((Mg,Fe)SiO3),[4] taken from the Tenham meteorite.

The study yielded results not seen when using synthetic samples, including a higher than expected presence of sodium and ferric iron.
