weathering - Opis:
- The researchInvestigations of secondary changes in the tree samples of Pułtusk meteorite, have brought more questions than answers. All the samples have well kept preserved fusion crust, which is built of tree parts. The external part is massive and compact, practically without any fractures whereas the middle part is cracked and porous. The internal part goes into the “black veins zone”. In the middle zone of the crust, skeletal crystals of Fe-Ni spinel, - trevorite, were found. Minerals present within Pułtusk meteorite are differently variously weathered. In At the edges of meteorite the sulphide phases are slightly altered whereas the metallic phases are completely replaced by iron and iron-nickel oxides and hydroxides, which were party removed during cutting. Silicates and chromite are the best preserved minerals.
