A few Minerals

[bill henderson]

I've been having a lot of fun stuff with a new 4x5 Poloroid bellows converted to take my D200 and any other lens set up I can dream up. Works great with microscope objectives ,enlarger lens,etc. it: very sturdy for stacking photos.

All of these photos were taken with the D200,60mm Micro, stacked using Helicon, camera atop the bellows unit using the worm gear for focus. Fiber optic Lighting

Beautiful pictures Bill. The Vanadinite in the first specimen is very clear I really like the way the axial angles are highlighted in the garnet. Is their an impurity in the garnet that makes it that color? I posted a vanadinite photo a while ago also. The stacks came out great.

I'm not expert enough about garnets to know about the composition of the outlines if any one can help on that we would sure like to know. I think its neat how each crystal has the outline

From what I understand about garnets, it is not possible to tell them apart visually. Most garnets are mixtures of two or more of the various garnet species. It takes a detailed analysis to tell what is what. Whithout such analysis, it better to label them garnet group. The tourmaline group is another group that takes a detailed analysis to determine what species you have. What was once done by color is nolonger a reliable way of telling tourmaline species apart.
