<dt>Description</dt>
<dd>Via Dave W. This is a stereo child photo. Nepheline syenite is one of the major rock types at MSH but good (or even recognizable) nepheline xls are few and far between. They have not been replaced by sodalite (as sometimes happens). The small pink xls are manganoeudialyte - see <a rel="nofollow" class="external free" href="http://www.mindat.org/photo-194327.html">http://www.mindat.org/photo-194327.html</a> The very dark green xls may be arfvedsonite. They are very etched and/or distorted on this side of the specimen but a few on the back do look like arfvedsonite. Reprocessed using CombineZ and replaced with higher res image Nov 2011.</dd></dl></dd></dl></dd></dl></dd></dl>
