Dara-i-Pech pegmatite field (Darra-i-Pech; Darra-e-Pech; Pech; Peech; Page), Chapa Dara District, Konar Province (Kunar Province; Konarh Province; Konarha Province; Nuristan), Afghanistan

Be-Nb-Ta-Li-rich pegmatites, hosted in a variety of lithologies. There are two types of pegmatites found within the ore field: (1) large albitized microcline pegmatites with beryl, and (2) spodumene-albite pegmatites with complex Li-Be mineralization.
Please note that Pech, Peech and Dara-i-Pech (also spelled Darra-i-Pech, Darrah Pech, and sometimes Page) are the same place. "Dara" means "valley", so in English the location name is "Pech Valley". Likewise, specimens labelled as coming from Dara-i-Pech do not necessarily come from this pegmatite field, but may originate from any place in the Pech valley. This area includes Chapa Dara, Dara-i-Pech, Wata Pur and Asadabad Districts in Konar Province, as well as Wama District in Nuristan Province.
Further note that many Afghanis will still use the name "Nuristan" in a traditional sense, to mean all of northeastern Afghanistan. This traditional meaning of the place name "Nuristan" is not to be confused with the current Nuristan Province, which covers only a portion of "Nuristan" in the traditional sense. Moreover, there also exists a Nuristan District, which covers a minor part of southern Nuristan Province.
