Olenii Creek (Olenii Ruchei; Oleny Ruchei), Khibiny Massif, Kola Peninsula, Murmanskaja Oblast', Northern Region, Russia In this specimen burbankite was decomposed with formation of very typical full of holes pseudomorphoses. The main constituent of these PS is honey-yellow very light coloured tabular synchisite-(Ce). Its tabular crystals form cellular framework of these pseudomorphoses, in holes of which grow small acicular balls of white strontianite. In these PS ... |
