@bewildered,
Im in the mining business for over 30 years and Im vwry familiar with the science and tech behind polarized light microscopy. You are not, so you are making idiotic statements when you have no fuckin idea what you are talking about. High viscosity melt liquids often collaps on their inclusions and the "bubbles" appear as if they were sunken at their margins. Sphericles, ooids, vesicles, oolites, inclusions, nd a myriad other liquid structures in minerals.
Dont be making statements anbout what is or is not evidence of geological structure cause you are totally ignorant of the subject.
You are trying to hawk your products and they are all full of crap. I can see why Mr Phillips is rustrated with your inability to understand PLM techniques.
Stop peddiling thios bullshit or peddle iot somehwere else, I think that noone here is convinced that you are even in the right area of inquiry.
PS, my own guess, based upon the fact that these vesicles are variously in or out of focus (indicating a greater thickness of sample on the focal level), is that these are glue bubbles from the balsam slide mount. Every microscopist makes errors in slide mounting and especially when the tolerance for the sample is 30 micron thick, the sample on the slide is much thinner than a newspaper sheet and its a glassine substance that is quite brittle . The balsam or acrylic mounting liquid will exert pressure onto the slide and cause breakage and this will gather up little amounts of bubbles that display just as we see them with various margin shapes and various polarization responses (usually the indices of refraction yiled toward what is called a color birefringemce which shows up as two colors
1 an ultramarine blue
2a lemon yellow.
These are NOT blood cells and to think so is lunacy. You arent another Nicholas Steno or Dr SChiller. You are someone who would greatly benefit by reading an introductory mineralogy and crystallography text (freshman level)..
