Please provide me original literature or reference material for the given equation.
Vitrinite Reflectance (Ro) % = -2.712 * log(V.M.) + 5.092
Where V.M. is on a dry ash-free basis.
I don't know if this will help but I do know Neely Bostick was one of the early researchers on this topic. You might also look at the work of Charles E. Barker. Bostick, N.H., 1971, Thermal alteration of clastic organic particles as an indicator of contact and burial metamorphism in sedimentary rocks: Geoscience and Man, v. Ill, p. 83-93.
Thank you Keith Winfree sir for helping but this equation is missing from the
above literature.
Yes but perhaps the references cited would have have it. Alternatively, the equation may have been developed later. In 1980, I was an undergraduate intern working in Bostick's lab at the USGS and they, particularly Charlie Barker and Mark Pawlewicz, were gathering new data from fluid inclusions to calibrate the correlation so you might look at publications after that. As you may already be aware, one of things geologists learned later is that the presence of liquid hydrocarbons on the surface of the vitrinite can suppress the reflectance thereby underestimating maturity. You may want to see if new equations that account for that effect have been developed. In my experiecene of studying source rocks that effect can be important.

Dear Harald S Poelchau sir thanks for answering this above question, I'm unable to access the first article (if possible, please send me a pdf version of this article).
In 2nd article, I'm unable to find any relationship between the volatile matter and vitrinite reflectance.
