Khan Bogdo is the largest in the world alkaline granite massif about 100 km in diameter. Of course it contain hundreds of pegmatites of different sizes and dykes of eakerite and other alkaline rocks and hydrothermalites (which often are confused with pegmatites).
Why everybody, who has any sample from Khan Bogdo, consider that his stone is exactly from Dorozhnyi pegmatite??? Yes, it is the most well known pegmatite of the massif, because of 3 new minerals were discovered in it, but it isn't the single pegmatite of the massif!

Dorozhnyi pegmatite is small pegmatite completely damaged to the end of 70th, because of it was very accessible - located close to road (Dorozhnyi means located along a road in Russian). Moreover, during last couple tens years the pegmatite is buried under sand dune and completely invisible under sand layer about 5 m thick (N.V. Vladykin data). So appearing of new material from here, collected in 90th-2000th, is very questionable.

Dear friends, please switch on your brains and stop to label ANY Khan Bogdo specimen as coming from Dorozhnyi pegmatite! Try to imagine space equal to three-four New Yorks. Why any sample from it should be labeled "from Manhattan"? Only because everyone had listen about this street?

Not any pegmatite of Khan Bogdo massif, even located right in the middle of road, is the Dorozhnyi pegmatite!!!
