From theCambridge English Corpus In the tridymitic xenoliths, silica is not associated with calc-silicate minerals that can help to indicate pressure and temperature conditions. From theCambridge English Corpus Layers wedge out along the upper part of axenolithjust below and to the left of the hammer. From theCambridge English Corpus However, there are significant differences between the two analysed xenoliths. From theCambridge English Corpus Since it is not exposed, this can only be attempted by using xenoliths derived from these basements. From theCambridge English Corpus Cores consisting of xenoliths or large megacrysts have not been observed.
