Paragonite and siderite are exclusively identified within the halos of 1-3 m in diameter close to ore bodies that were only recorded at XRD data.
From the Urals, were masses of nearly pure scaly paragonite from Slyudorudnik, Vyshtym; pecoraite from Tscheremschanskoe; sonolite, alleghanyite, rhodonite, and alabandite from Inyltschek, Kyrgy; tobermorite, from Bazberovskoe; sellaite from Suranskoe, Bashkirien; and clintonite, from Shishimskie Gory.
