Abstract - Summary 
(short description):
The external and internal morphology of metal-oxide-silicate spherules from kimberlites of Angola is presented. Their chemical composition was studied and compared with the composition of kimberlite rocks of the Catoca pipe in the diagram (FeO+MgO)-(SiO2+Al2O3)-(CaO+TiO2). Evidence is given of their liquation nature and interaction with bubbles of volcanic gases, as well as arguments in favor of their natural origin. It is assumed that the spherules moved in the kimberlite melt together with the flows of volcanic gases, and their high contents are indicators of high-mobility magmatic «columns» in the diatremes of kimberlite pipes.
