. "Mineralogy and geology of locality Nechranice is the object of the article. This work briefly summarises the geology of surroundings and the characteristics of its deposit Nechranice itself. The characterization of the occurrence of quartz precious stones is the first result of the research. Main attention is dedicated to mineralogical analyses of 15 samples gained in the locality. The discovery and detail description of a unique palm tree petrified by rare mineral fluorapatite is the main result of our research." . "75172" . . .
