Opis:
This article complements the previous publication included in the materials for the 2nd Meteorite Seminar in Olsztyn in 2003 and also in 2004 in Meteoritics & Planetary Science with artifacts about which I did not write then and new discoveries. In recent time, archaeologists have discovered more confirmed artifacts that were made of meteorites. Scientists were puzzled that iron objects were found among the artifacts of the Bronze Age. Initially, it was assumed that these were the beginnings of metallurgy, but after careful research, it turned out that they are cold-forged items and the metal is of cosmic origin. How many more interesting and unusual old artifacts made by human hands from materials obtained from outer space will be discovered. Can there be more such artifacts in museums in Poland? It seems to me that a comprehensive inventory and research action should be carried out to verify this. Finally, as a lawyer, I can add that artifacts made of meteorites are the only meteorites in the world protected by law in one hundred percent, because they are monuments of world material culture.

Opis:
Iron meteorites are the only ones to be linked with terrestrial impact craters. As studies show, over half of all iron meteorites shows signs of being shocked some time in their history to pressures over 130 kb. This paper is a short review of main shock metamorphism features in iron meteorites. Mechanisms leading to forming shock metamorphism features are described and examples of application of shock metamorphism studies are given.

Scattering Mössbauer spectroscopy
Opis:
Non-destructive Mössbauer spectra (MS) of a series of nine Mexican iron meteorites belonging to the collection of the Instituto de Geología of the Universidad Nacional Autónoma de México (IG-UNAM) were obtained by 90º γ-ray scattering. We divided the set of nine meteorites in two groups: The first group shows complex spectra of iron oxides mixed with a paramagnetic phase; their spectra and Mössbauer parameters have noticeable differences. The spectra of the second group are quite similar and characteristic of Fe-Ni alloys.

Opis:
This article describes the results of metallurgical studies of three experiments on hammering products made of iron meteorites. The objective qualification criteria of these materials created by plastic deformation were defined: carburization in smithing hearth, creating martensitic structure and the existence of small-martensitic weld and increased content of nickel.

Opis:
Sixteen specimens of the Morasko, one specimen of Seeläsgen and one specimen of Jankowo Dolne irons were analyzed with INAA to determine contents of 14 siderophile elements. The samples selected for analyses have their structures described and the presence or absence of cohenite checked. For preliminary interpretation, we have chosen elements determined with highest accuracy: Co, Ni, Ga, As, Ir and Au. The results are shown in tables and diagrams. It has been found that there are no significant differences in composition between fragments with and without cohenite. The observed low contents if iridium are not accompanied by lower contents of elements showing similar behavior during crystallization: platinum and tungsten, which suggests that fractional crystallization was not the reason of lower iridium content. Similar concentrations of elements have been found in all the Morasko specimens, and in the Seeläsgen and Jankowo Dolne irons, which suggests that all these meteorites come from one iron shower.

Opis:
Fossil iron meteorites are extremely rare in the geological sedimentary record. In the boundary clay from the outcrop at the Lechówka quarry (Poland), fragments of the paleometeorite were found in the Cretaceous-Paleogene boundary clay layer. The fragments of meteorite (2–6 mm in size) and meteoritic dust are metallic-grey in colour. Analyses of the meteorite from Lechówka reveal the presence of Ni-rich minerals with a total Ni amount of 2–3 wt%. They are represented by: taenite, kamacite, schreibersite, Ni-rich magnetite, and Ni-rich goethite. The investigated remnants of paleometeorite apparently represent an independent fall and does not seem to be derived from the K-Pg impactor.

Opis:
Radioactive cobalt isotope 60Co is produced in neutron activation process of stable isotope 59Co by neutron capture reaction 59Co(n,g)60Co, in solar wind charge exchange 60Ni(n,p)60Co or in spallation process 62Ni(n,p2n)60Co. These processes are responsible for isotope 60Co production either in nuclear reactor on Earth or beyond – in stars and in meteorites (induced by cosmic rays). In this work the results of 60Co measurements in metal sources by gamma spectrometry laboratory are presented. A metal reference radioactive standards made up of steel cast with discs shaped geometries and different diameters have been tested in gamma-ray spectrometry measurement system. The reference activity concentrations of 60Co were in the range of (0.291±0.010) Bq·g–1 to (1.544±0.030) Bq·g–1. The mean minimal detectable activities (MDA) obtained by series of the 6 to 18 hours lasting measurements of described above standards with HPGe detectors carried out in NCBJ OR POLATOM were in the range of 6.1 mBq·g–1 to 8.5 mBq·g–1. The results correspond to the values of 60Co activity concentration measured in the iron meteorites with young terrestrial ages.

Opis:
The research was focused on strewnfield in “Meteorite Morasko” reserve. The main goal of the project was to find correlation between chemical composition of soil and concentration of cosmogenic material which was discovered in the region. After field prospection the sampling was made for three reference regions in the reserve. ICP-MS method was used to determine the elemental composition of soil samples. Investigation has been carried out to indicate the chemical components which iron meteorite matrix is built of like Fe, Ni and Co. Results of the study gave information about distribution and correlation of chemical components in the reserve.
