This is my first time using this software. I was instructed by my supervisor to look into ImageJ software to identify different minerals present in a thin section. I’ve look at many videos and different application methods, but still having trouble with the threshold.
The thin sections I have are hawaiian basalts and comprise of plagioclase, pyroxenes, olivine, and vesicles. It is very hard to identify each mineral when plagioclase is half white and half black and blends in with the groundmass. Under cross polarized light, the same minerals have different colors and vesicles blend with ground mass. I have tried 8 to 36 bw bit and the color bit as well.
Is there any way to find out what the percentage of each mineral is in the picture with ease?
Here’s a sample of the thin section I would be working with. I need to find the percentage of vesicles, pyroxenes, plagioclase, and olivine.
Thank you for your time and help!
