Analysis Data

More than 500,000 data of meteorite analyses are stored in MetBase, such as:

Chemical analyses:
» Bulk chemical compositions (oxide compounds)
» Major, minor and trace elements in chondrites, achondrites and silicate phase of other types
» Major, minor and trace elements in iron meteorites and metal phase of other types
Mineral chemistry: olivine, pyroxene and plagioclase compositions

Isotope analyses:
» Noble gas isotopes and cosmic-ray exposure ages
» Cosmogenic radionuclides and terrestrial ages
» Light stable isotopes (oxygen, nitrogen, hydrogen)

Physical properties:
» Thermoluminescence data (NTL, ITL)
» Densities and Porosities

» Bulk chemical compositions Usually wet chemical analysis (oxide compounds) of bulk samples are stored in this section.

» Major, minor and trace elements in non-irons Mostly INAA, RNAA and ICP-MS analyses of bulk material.

» Major, minor and trace elements in iron meteorites Most iron meteorites are analyzed using INAA (instrumental neutron activation)

» Cosmogenic radionuclides Long-lived radionuclides 10Be, 14C, 21Ne, 26Al, 36Cl, 41Ca and 53Mn and calculated terrestrial ages.

» Light Stable Isotopes Oxygen, carbon, nitrogen and hydrogen isotopic compositions and abundances of carbon, nitrogen and hydrogen in meteorites

» Noble gas isotopes Single step and stepped combustion analyses of helium, neon and argon isotopes as well as cosmic-ray exposure (CRE) ages.

» Porosities and densities Measured and model porosities as well as bukl and grain density data for stony and stony-iron meteorites

» TL data Measurements of induced and natural thermoluminescence (ITL, NTL) of chondrites and achondrites.
