Origin of andradite attributed to Parachinar, Kurram Agency, Federally Administered Tribal Areas (FATA), Pakistan is actually Marki Khel (located southwest of Jalalabad) in Nangarhar Province, Afghanistan. Dudley Blauwet.

Further Note Added - July 2010: Identical specimens that are now being made available are said to come from Khogyani, which is a district in southwestern Nangarhar Province.

Further Note Added - March 2011: Specimens of andradite and magnetite vaguely attributed to "Speen Ghar" probably come from this locality as well. Spin Ghar (Speen Ghar) is the name of the mountain range that trends along the border between Afghanistan and Pakistan in southern Nangahar Province.
