Field determination of the % dolomite in dolomite/limsestone chip samples

[00rich]

Does anyone have any tips on determining dolomite percentage in a well-site setting?

I was thinking that comparing the rate of effervescence in a 10% HCl in water solution could give some quantitative results. Maybe comparing the rate while changing parameters such as temperature of solution, strength of HCl solution or powdered vs solid sample. I could make a chart with the rate of known samples under these different conditions to compare to.

 

I haven't tried this yet but what do you think? Any tips or better ideas? Thanks!

 

To be clear I mean % dolomite in limestone/dolomite samples
