Chondrules
|
|
Our group studies meteorite chondrules
by:
|
1.
analysis of the composition of individual phases minerals and in chondrules by electron microprobe analysis
|
2.
bulk analysis by instrumental neutron activation analysis
|
3.
isotope analysis in collaboration with other groups
|
We are especially interested in:
|
1.
Documenting the
range of chondrule properties, especially with
respect to composition. To this end we
have proposed a compositional classification scheme for chondrules
which we have applied to ordinary chondrites and plan to extend to
carbonaceous and enstatite chondrites.
|
2.
Reactions occuring during chondrule
formation, these being mainly the loss of volatiles, reduction of FeO and other species and isotopic fractionations and
exchange with ambient gases.
|
3.
Formation of chondrules.
|
Below is the chondrule
classification scheme devised for ordinary chondrites using cathodoluminescence
(Sears et al. 1992).
