DTSA quant
Hi I am trying to analyze inclusions inside of a host mineral. It seems that others have been working on this problem as well and it would be great to get any advice you can share.
I have some EMPA analyses of inclusions. My plan has been to run DTSA II simulations of inclusions with an initial estimated composition and then iteratively determine ZAF corrections.
My inclusions are 0.5-2 micron melt and mineral phases trapped in a diamond matrix. I am mostly concerned with getting a decent estimate of the major elements normalized to 100 wt%. There is also H2O and C in these samples but excluding them should probably be okay for most samples.
It's hard to determine the exact size and depth of my inclusions so I over scanned them during data acquisition but it's hard to know by how much, I didn't think this would be a large issue since there is little overlap in elements besides carbon. For the depth, my plan was to run simulations at various depths to estimate the uncertainty on the composition.
My standards were all homogenous mineral phases so definitely not matrix matched.
Are there any major pitfalls I am overlooking?
Thank you,
Henry
