Description
Summary:This text deals with the geochemistry of iron ores. By means of spectrochemical analyses some significant minor constituents have been determined in samples mainly from the pre-Cambrian iron-ore regions of Sweden. For the sake of comparison some samples of iron ores of different age from non-Swedish regions have been analysed. On the basis of the analytical data available some significant statistical quantities have been computed in iron ores as well as in the main igneous rock series. Special regard has been paid to the relationship between the distribution principles governing some major constituents in the iron ores, on the one hand, and in the igneous rocks on the other. A method is proposed for geochemical investigations of igneous rocks by means of statistical data. With the aid of geochemical premises the endogene relationship between iron ores and their associated igneous rocks has been discussed. A theory on the principles governing the formation of iron ores has been advanced and employed with ... : From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis...) not present in the NOAA-MMS database. ...
