Are we really analyzing the samples we want to analyze? Examples of naturally occurring ultramafic r

Abstract

Ultramafic rocks are present in a variety of tectonic settings on Earth.We believe that the origin and history of ultramafic rocks can provide information on the processes of partial melting and melt migration and extraction in the mantle and on the tectonic evolution of geologic units containing ultramafic rocks. In the presentation, however, we would like to share our experience that natural samples should be carefully examined to determine where and how they were formed.
