Volcanic Ash

bfesser - 1-3-2014 at 17:44

I'm curious; does anyone else here collect volcanic ash?

My collection so far:
<a href="" target="_blank">Grímsvötn 2011</a> <img src="../scipics/_wiki.png" />
<a href="" target="_blank">Eyjafjallajökull 2010</a> <img src="../scipics/_wiki.png" /> &mdash; ash from April 29th, 2010 at the <a href=",0," target="_blank">Steinar farm</a> <img src="../scipics/_ext.png" />
<a href="" target="_blank">Mt. St. Helens 1980</a> <img src="../scipics/_wiki.png" /> &mdash; coarse ash from USGS observation post (1); medium ash from Spokane, WA (2); fine ash from Yakima, WA (3)

I have the same Mt. St. Helens 1980 collection, nothing else besides that.
I don't actually collect ash though.

Would there be any sulfur containing compounds in the ash?

Cool! I was researching about volcanic ash just a while ago.
No, I actualy don't have any myself, but my dad was in Washington when Mount St. Helens erupted. He has a jar with over 8 lbs of ash, which he collected himself. He had climbed the mountain just weeks before the eruption took place.
[EDIT] Typo.

Meteorites & Tektites

Would there be any? Yes. Are they significant? Not really (<a href="" target="_blank">USGS ref.</a> <img src="../scipics/_ext.png" />, <a href="" target="_blank">Wikipedia ref.</a> <img src="../scipics/_wiki.png" />;). Are they worth extracting for amateur laboratory use? Definitely not.

I suppose volcanic ash collecting is a little obscure; so how about <a href="" target="_blank">meteorites</a> <img src="../scipics/_wiki.png" /> and <a href="" target="_blank">tektites</a> <img src="../scipics/_wiki.png" />; does anyone else here collect them?

I only have a humble collection&mdash;currently ten meteorite fragments and one Czech <a href="" target="_blank">moldavite</a> <img src="../scipics/_wiki.png" />&mdash;but am awaiting the arrival of another meteorite and tektite in the mail. I've already posted photos of <a href="viewthread.php?tid=14644&goto=search&pid=297682">three of my specimens</a>, but could try to take photos of the others if anyone's interested. Likewise, I'd really enjoy seeing photos and reading details of others' collections.

I'm also fascinated by other <a href="" target="_blank">impactites</a> <img src="../scipics/_wiki.png" />, <a href="" target="_blank">tephra</a> <img src="../scipics/_wiki.png" />, and the like. I recently tried to get a sample of some <a href="" target="_blank">K&ndash;Pg (formerly 'K&ndash;T') boundary</a> <img src="../scipics/_wiki.png" /> material from Agost, Spain, but missed my opportunity. Surely I'm not the only one interested, so please feel free to share anything related.

Here's my dad's Mt. St. Helens ash.
Doesn't really look very interesting, looks just like fireplace ash.

[EDIT] I don't collect either ash or meteorites, I might start though.
