Name:
Named in honour of Alexandr Efimovich Zadov (1958-2012) - Russian mineralogist and mineral collector, specialist in mineralogy of calcian silicates. He is author or coauthor of more than 90 new mineral descriptions.
A mineral of a novel modular structure type related closely to the structure of nabimusaite. The P analogue of aradite. Differs from gazeevite in substitution of one of the phosphate groups by orthosilicate, the latter two by sulfate, and fluoride by oxide.
Structure related especially to that of gazeevite, being of gazeevite-zadovite type. The structure is of modular-layered type, derived from that of hatrurite. More specifically, it has single (broken) antiperovskite [WB6](TO4)2 layers.

Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.
Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.
Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars.
