More Foram Fun

#1 Post by KurtM » Sat Mar 09, 2019 2:34 am

While excavating through the archives I ran across this image of a little arrangement of forams that I posted a while back, but hope you won't mind if I repeat it because it got me fired up to retrieve the sample, dig a few more out, and have a little fun trying to make some interesting new pix. Then Cuxlander posted his beautiful foram image yesterday, so here are a few I ended up with to keep the ball rolling.

First, the original bunch I already ran past you:

The idea was to give the viewer a feel for size in a way a little more juicy than a dry scale bar, so I posed one in the eye of a #12 sewing needle:

Then it occurred to me that we seldom, if ever, see forams presented as they are found, among the grains of the sand sample they were discovered in:
3-7-19 DMap 2_lzn 1024px.jpg

And finally, you just gotta put the sand under crossed polarizers, right? Texas beach sand appears to be largely quartz, I'd say:

Just a little fun in the lab...

Attractive, cool photos! I like them all.
why is the foram absent from the polar image ? would demonstrate the difference from the quarz grains.

Where were you when I needed you? :lol: Guess I gotta go back and re-do that one...
