A few months back I heard something quite small and hard hit my house roof, which is tin so it was pretty obvious. I suspected it may have been a cherry-pip that a bird had dropped from a nearby orchard. Turns out that's exactly what it was!!! Only, when I was up there getting my extraordinarily rare meteorite in the new classification, 'cherrypipite'; I actually found around 5-10 very small, dark brown-black stones. This intrigued me as they didn't seem to fit into the surounding geology. Although I was 99% sure they were not of meteoritic origin, I decided to email an expert. He thought as I did; that a bird had also probably dropped them onto the roof!!! They were some form of everyday common 'Buckshot gravel'. (Largely composed of iron oxides. Typically the mineral maghemite is present making them strongly magnetic.) When I went and had a closer look at the surrounding ground, I was able to find some of this material. But it probably only make up around 0.1% (if that) of the surface stones. So how is it that these less common stones were the only type on the roof??? WELL! My Theory! Some birds actually swallow small stones to aid in their digestion. All these Buckshot gravel stones (both roof and on the ground) are a similar small size, quite rounded with no sharp edges and their very dark colour stands out against the other pale clay-based rocks. I believe these birds have learnt to go for these tasty little buckshots!!! Has anyone else ever heard of this or know anything about it? Hope this has provided a bit of light refreshment from some of the current postings and if anyone else has a funny or quirky story about meteorite related stuff, I'm sure quite a few on the list wouldn't mind hearing it! After all; that's what it's all about! Have fun, Jeff K. http://my.yahoo.com.au - My Yahoo! - It's My Yahoo! Get your own! Received on Tue 29 Jan 2002 09:32:27 AM PST |
