iron silicide

New occurrence of iron cilicide in the Ukraine. Cosmogenic or telluric nature?

Several type of particles that is completely or partially  made of iron cilicide  have been collected in different site of Ukraine. Aim. Our objective is to recognize the primary nature of these substance based on detailed study of mineralogy and chemical composition. Methodology. We summarized published information and draw inferences derived from the interpretation of mineralogical, microprobe and x-ray date. Results. Here we distinguished three types of ferrosilicium-bearing particles.
