Meteorite found in Africa is older than the Earth

[UM-Bot]

Scientists have been studying a meteorite that dates back to a time before the birth of our solar system.

In danger of sounding ditzy...

Neat!

Super Neat!

Incredibly neat!!     A piece of our solar system before it really was one!  Was the Sun still forming or already there and just gathering its disk?

I wonder how they date such a thing.

Not doubting the authenticity ... but I did wonder the same thing.

Carbon dating, presumably ?

Only if you think the Earth is less than 60k years old.

Aluminium-26 can be used to calculate the terrestrial age of meteorites. After the breakup of the meteorite parent body, it will be bombarded by cosmic rays, which will saturate it in aluminium-26. After falling to earth, ²⁶Al production ceases, which means that the amount of ²⁶Al in the sample can be used to calculate the date the meteorite fell to earth.

The ²⁶Al–²⁶Mg isotope systematics were determined for whole rock (WR) and mineral separates of NWA 11119 (Supplementary Data 7). These define an isochron corresponding to a ²⁶Al/²⁷Al ratio at the time of crystallization of this sample of (1.69 ± 0.09) × 10⁻⁶ (Fig. 5). Previously, the highest value reported for an achondrite internal ²⁶Al–²⁶Mg isochron was (1.28 ± 0.07) × 10⁻⁶ (for the ancient cumulate eucrite Asuka 881394²⁷). Relative to the D’Orbigny angrite age anchor^28,29, the ²⁶Al–²⁶Mg age of NWA 11119 is 4564.8 ± 0.3 Ma (Fig. 5). It is also possible to calculate a ²⁶Al–²⁶Mg age relative to the first-formed refractory solids in the solar protoplanetary disk that are characterized by a canonical ²⁶Al/²⁷Al ratio of 5.2 × 10^{−5 30}. However, the reported Pb–Pb ages for these refractory solids span ~0.6 Ma^30,31,32, leading to a range of ²⁶Al–²⁶Mg ages of 4563.7 ± 0.2 –4564.4 ± 0.3 Ma for NWA 11119. Consideration of the full range of these ²⁶Al–²⁶Mg ages (obtained relative to the D’Orbigny angrite or the refractory inclusions) and the Pb–Pb ages of the refractory inclusions^30,31,32 indicates that NWA 11119 was formed 2.5–3.5 Ma after the first-formed refractory solids in the solar protoplanetary disk.

And if its older than earth..
