Abstract. The age of ore deposits constitutes a decisive element in understanding their formation. Deciphering precise chronology may be challenge the absence mineral phases that can dated by conventional geochronometers. Fluorite is very common either as major or accessory wide variety ores and provide information regarding origin timing mineralizing fluid flows. In this contribution, we explo...

Fluorite mineralization associated with different types of magmatism is common in the Western Transbaikalia. This study deals Arshan, Yuzhnoe, and Ulan-Ude fluorite occurrences, which are most significant examples carbonatite-related region. The present paper focused on new geochemistry fluid inclusion data, aimed at revealing conditions formation, highlighting its genetic relationship magmatis...

It is well-known that many natural fluorite crystals contain rare earth ions. In this work, a series of pink fluorites studied to demonstrate the use Raman microscopes allows obtain high resolution emission spectra trivalent These allow in principle distinguish differences local environment related charge compensation necessary when divalent Ca ion replaced by ion. The from Alps have grown unde...

In this research Calcium fluoride nanoparticles and its different amount of cerium ion dopant (5%and 10%) were prepared. The mentioned nanoparticle were studied by fourier transform infrared spectroscopy (FTIR) , X-ray diffraction (XRD), absorption and photoluminescence spectra (PL) and Scanning electron microscopy (SEM). The XRD patterns indicate a typical cubic fluorite structure and no other...

In order to make better use of converter dust achieve effective pre-dephosphorization molten iron, the influence addition ratio dedusting ash and oxide scale on dephosphorization iron was compared, so as reveal reasons for decrease rate caused by dust. Through theoretical analysis, XRD, SEM-EDS, Raman infrared spectroscopy, mineral phase structure, polymerization degree phosphorus structure fin...
