Petrologic Meteorite Slides

Chassigny Martian Meteorite under cross polars

The purpose of this page is to present these remarkable slides taken from my meteorite collection.

 

My Unitron Metallographic BU-11 microscope used to take the images of slides. This microscope can be used to examine metals such as in meteorites, and for petrologic studies for which I use it most.

The following images were taken with the abovementioned instrument, and my "Polaraview" a special hand held cross polorizing viewer.

 

 NWA 998 Martian Meteorite, Nakhlite

 

SHISR 007 urelite

 

 

Bilanga achondrite. Close up through my special viewer.

 

NWA 869 chondrite

Enlargement of very small capillary with blood cells nearly one by one. Area surrounding it is white matter with glial cells, astorcytes, oligodendrocytes, macrophages and monocytes. Macriogages and monocytes are the white masses outside of the vein and are causing demyelination of the white matter. 400X

 

Cells, damaged in the cut edge of brain sample showing disturbed axions, glial cells, oligodenrocytes, and red blood corpuscles. 400X

 

Virchow-Robin space surrounding blood vessels within demyelinated, diffusely edematous white matter. 400X

 

A very nice 500X photo of a branching Purkinje cell and neuron below it in affected white matter.

 

Another image of neurons with axions, Purkinje cells, and extremely small capillaries. 500 X

 

This incredible 300X image is of a spiral blood vessel with red blood cells within. The white areas are macrophage cells, and these have permiated the vessel walls penetrating white matter causing demyelination. The actual size of this view is > .1 mm.

I would like to extend my appreciation to members of the Flagstaff Medical Center Pathology Department for preparing and presenting to me these re-cuts from original tissue extracted from my brain on January 10th of 2003. The biopsy report described this as a "large brain biopsy" done when I was in a coma from this debilitating and nearly fatal condition. They did not expect me to survive. But, thank God I did, and am on the road to recovery. Needless to say, there are however certain disabilities that remain, and in light of this my former vocation as a computer technician is in question. But these slides have sparked my mind to study this rare condition, at least in thought and personal interest. That I survived this condition is a miracle, and in my current state of mind, looking at my own brain, to see and comprehend the things that I am seeing is awesome and inspiring-- Even more I think than I would feel if in space, or standing on the moon. Someday, perhaps I will write in layman's terms a story detailing this experience and what is currently known about this strange and rare disease. But for now I invite you to search the links that I have found.
