Abstract
The structure of the orthorhombic modification of lazurite from the deposit of the southwestern Pamirs is determined (sp, gr. Pnaa, R-hkl = 0.068, 146 0 reflections). The character of the commensurate modulations of the displa cements and the replacements of all the atoms in the structure is studied. Three types of sulfur radicals that replaced chlorine atoms in the sodalite -type structure are established.
