... within the two crystallographically unique T O 4 tetrahedra are 1.734 and 1.526 Å, respectively. From the scattering power at these T sites and the stereochemistry, the presence of an AlO 4 tetrahedron linked to a PO 4 tetrahedron is established. Consequently, the sample from Cioclovina Cave is verified...
