Britholite-(Y) brown glassy grains in quartz matrix with minor black Magnetite. This britholite is Y-dominant, but REE spectrum displased to the left side with the maximum on Ce. So the main alteration product of this Britholite-(Y) is Bastnasite-(Ce) - its yellow masses are well visible at right part of specimen. Minute snow-white films of Tengerite-(Y) are visible in central part of the specimen. Its size is 8x7x5 cm and radioactivity is 1024 μR/h. Pavel M. Kartashov collection and photo.
