minerals, inclusions The CAI content, SiC content, nanodiamond content and noble gases of Kaba are also worth investigating. Since Kaba has a high carbon content (ca. 2.0 wt%), the investigation of various carbon modifications is also promising. These include weakly graphitized carbon and fullerenes. Among these, the study of nanodiamonds was carried out by cathodoluminescence method. CAIs (calcium-alumina inclusions) are the oldest mineral outcrops in the Solar System, with an age of 4.567 gigaannum (Ga), or 4.567 billion years (Allende measurement). The surrounding rim (Wark-Lovering-rim) shows how dust layers were thermally precipitated and burnt onto the CAIs. The CAI (white inclusion) of Kaba is also worth re-examining because Kálmán Sztrókay was the first to measure the mineral composition of the CAIs in the Kaba meteorite and found them to be spinel. Since then, the layered stacking of several mineral components has been detected in CAIs. Shock Kaba's transformation by impact pressure was measured as S1 (shock stage) on a 0-6 scale. The weak stratification attests to this. The laminated fabric structure was measured at Eötvös Loránd University on a sample of Kaba meteorite from the 13 December 1995 cut-off. The stratification was confirmed by a new analytical method (computer tomography scanning). Conference on the Kaba meteorite In the autumn of 2017, an international conference was held at the Debreceni Református Kollégium on the latest results of research on the Kaba meteorite. The material of the twenty-two presentations was also published in book form. References Further reading McSween H. Y.
