Chemical Bulk Analysis of the WILUNA:
SiO2=39.59%, TiO2=0.10%, Al2O3=2.65%, Cr2O3=0.63%, FeO=9.5%, MnO=0.27%, MgO=24.06%, CaO=1.88%, Na2)=0.95%, K2O=0.10%, P2O5=0.16%, H2O+=0.08%, Fe m=14.73%, Ni=1.58%, Co=0.081%, FeS=3.39%.
Radiometric dating of the meteorite itself estimates an age of about 4.5 billion years, suggesting it was formed at the very beginning of the Solar System, and which makes it among the oldest material known to exist ( the oldest rocks on Earth being only half its age!).
