A possible terrestrial analogue for haematite concretions on Mars
WebAccommodation of Martian data by hematite is a result of differences in optical and magnetic properties of sp-Hm and bulk-Hm particles. Optical, magnetic, and Mossbauer properties of sp-Hm particles dispersed within particles of high-area silica gel are reported in this study and compared to the corresponding properties of bulk-Hm powders. Webform of hematite (50 - 75%), followed by basic iron sulphate (20 to 30%), with only about 10% in solution as ferric sulphate. The data suggested that ~90% of the basic iron sulphate decomposed to ferric sulphate in solution during hot curing, and there was no change in the amount of hematite (after correction for mass loss in hot curing). consulting proposal letter template

Thus, goethite/hematite ratios in terrestrial and marine deposits have been widely used to infer past climatic changes. edward feldmann
