Collaborators:
In northern Kazhakhstan, ultrahigh pressure metamorphic rocks containing metamorphic diamonds are exposed. Petrological studies on these rocks reveal that these have been subducted to a depth of at least 170 km (P-T conditions of 1000 °C/ > 45 kbar). In collaboration with N.V. Sobolev and V. Shatsky (Novosibirsk), cathodoluminescence studies (with complimentary electron microprobe analyses) were carried out on banded diamond bearing pyroxene-garnet-cabonate rocks. Among other findings, these methods revealed garnets which have been intersected by multiple crack systems. Whereas the late fractures are visible in a polarizing microscope, the earlier fractures have healed with the garnets (marked by low Ca- and Mn- and correspondingly high Fe- and Mg- contents). Cathodoluminescence studies revealed other interesting features such as zoned pyroxenes (whose CL-colors change according to Fe and K contents), blue luminescent pyroxenes (=exsolutions in K-feldspar), spinel-pyroxene symplectites around garnet and variably luminescent carbonates (e.g. dolomite exsolutions in calcite, late formed Mg-calcite etc.).
