Mössbauer analysis of iron compounds in the Earth's soils and some soil from mars.

The article presents a study which aims to determine the quantitative and qualitative correlations of the mineralogical components of Earth soil and rocks from Mars and analyze the problems on the theory of their joint formation. It says that the research used Mössbauer spectroscopy (MS) to analyze the three groups of samples from the soil-bioclimatic zones of the Earth, rocks from Mars obtained by the Martian rovers Spirit and Opportunity, and a ferric chloride (FeCl3) solution-clayey mineral. It says that comparative analysis of the MS data revealed that the hematite-goethite ratio and effective magnetic fields of iron nuclei are different for Earth and Mars. Furthermore, the combined magnetic and electric superfine parameters in the hematite are different.
