Hi,

I was recently sent a rock, the accompanying story was that it landed near someone with high velocity and was warm/hot to the touch. (Normally this story rings alarm bells as meteorites are generally not known to be warm especially small ones), however upon looking at the rock, it appears to have chondrules (or chondrule like objects), but has no fusion crust.

?Its about 27mm x 19mm, and is very slightly attracted to a strong magnet, (enough for the rock to move when a magnet is put next to it.

I can't explain what i'm seeing, these chondrule like features are near perfect spherules!, ?however I can't see any metal grains!

Under mag there are numerous spherules, and other unidentifiable ?inclusions, the matrix is a grey to light beige colour.

Anyone care to take a stab at what this is?
