Description:
Observations by transmission electron microscopy show that lamellae of clinoenstatite are present in diopside grains of the Alpe Arami garnet lherzolite of the Swiss Alps. The simplest interpretation of the orientation, crystallography, and microstructures of the lamellae and the phase relationships in this system is that the lamellae originally exsolved as the high-pressure C-centered form of clinoenstatite. These results imply that the rocks were exhumed from a minimum depth of 250 kilometers before or during continental collision.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bozhilov -- Green 2nd -- Dobrzhinetskaya -- New York, N.Y. -- Science. 1999 Apr 2;284(5411):128-32.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Geophysics and Planetary Physics and Department of Earth Sciences, University of California, Riverside, CA 92521, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10102809" target="_blank"〉PubMed〈/a〉
