The shock-loaded gabbro resembles meteorites of the shergottite class; this suggests that the latter formed as a result of shock. The shock-loading of gabbro at 600 to 800 kilobars raised the temperature above the melting range of the plagioclase.</p></div></div><span id="related-urls"></span></div></div></div></div></div></div></div></div></div></div></div> application/pdf 10.1126/science.140.3567.670 en AAAS Maskelynite: Formation by explosive shock article
