In this thesis I report the petrographic, elemental and isotopic (oxygen, Al-Mg, Rb-Sr and uranium) compositions as well as U-Pb ages of five coarse-grained igneous inclusions (Type A CAIs 1 and 4a, Type B CAIs 5, 6 and 7) from the CV chondrite North West Africa (NWA) 4502 the second largest CV chondrite so far after Allende.
At a mineralogical level, NWA 4502 is rather pristine. In comparison with CAIs from Allende and other CV chondrites, CAIs from the NWA 4502 show many similarities with...[Show more]
