Add to ORKGX-ray absorption spectroscopy (XAS) measurements for Ca3Ga2Ge3O12 and Ca3Ga2Ge4O14 glasses are presented. In particular, the extended X-ray absorption fine structure (EXAFS) spectra are analysed and local neighbourhood of Ga and Ge atoms is described in detail. The Ge/Ga atoms neighbourhood in considered glasses is compared with the data available for corresponding crystals. Performed comparative crystal-glass structural analysis confirms correlation between crystalline and glassy structures of the Ca3Ga2Ge3O12 and Ca3Ga2Ge4O14 compounds. Our results provide several new detailed data, and some general suggestions on the CaO-Ga2O3-GeO2 glass structure
