Emmons's 1943 GSA Memoir 8; but no use of a universal stage: http://tinyurl.com/oz98vpu<br>Unique aspect: statistical significance. Don't bring any particle to a known optical orientation before comparing its RI to that of immersion liquid previously calibrated for RI=f[?(nm),T(°C)].<br>The work tests the notion that the rapid assignment of refractive indices (RIs) displayed by particles encountered during double-variation, liquid-immersion microscopy; to categories L (Less than), E (Equal to) or G (Greater than); might produce statistically-significant data sets unavailable to Optical Mineralogists who so painstakingly orient each particle to a known optical orientation before making such an assignment. <br>RAW DATA with Explanations, DOI: 10.13140/RG.2.2.19270.83529<br>Paper tentatively entitled "Given Einstein’s E=mc2: Estimation of mass concentrations [m]; technique applied to RIs displayed by a powdered Hawai’ian gabbro sample" is scheduled for 2nd-Quarter 2020 issue of https://www.mccroneinstitute.org/v/72/the-microscope-journal <br>805 N.
