MATERIAL OF COMETARY NUCLEI AND ASTEROIDS CAN BE STUDIED IN THE EARTH’S ORBIT
Odessa Astronomical Publications, 2019 The Solar system is formed from a pri- mary gas-dust cloud. Asteroids and cometary nuclei are made of the same substance. Therefore, the study of their debris will help determine their properties.

The Dehydration of Serpentines and Extraction of Water
The Planetary Science JournalSome groups of carbonaceous chondrites are dominated by phyllosilicates, specifically the serpentine group, which are characterized as alternating layers of silicates, metal cations, and hydroxyl (OH). Both antigorite, an Mg-rich member, and cronstedtite,

NWA 11562: A Unique Ureilite with Extreme Mg-rich Constituents
The Planetary Science JournalA comprehensive study of an ungrouped achondrite meteorite, North West Africa (NWA) 11562, was conducted, involving petrology, mineralogy, and mass-independent chromium isotopic composition. NWA 11562 comprises 34.9 vol% olivine, 56.1 vol% pyroxenes, 6.7

Chemical Composition of the Mantle and Meteorites
Journal of Geography (Chigaku Zasshi), 1964 In the past, petrological data have provided the principal contributions towards our knowledge of the constitution of the meteorite. It is now possible to look into the differentiation of the meteorites in which a wide variety of properties are reasonably well specified by the similar way as in petrological studies.

Trace element composition of troilite, iron and iron-nickel metall from meteorite Chelyabinsk
Литосфера, 2015 We studied the contents of trace elements in troilite, iron and in iron-nickel metal from meteorite Chelyabinsk by means of LA-ICP-MS. The features of the distribution of siderophile and chalcophile elements in sulfide and metallic phase in gray and ...
