1/Would you please suggest me some specific ideal rock unit/sequence of known provenance on which one can validate his /her provenance model. For modelling i am thinking of using whole rock geochemistry and trace element for less transported sedimentary rock .
2/what can be the approach when dealing with effect of hydraulic sorting and diagenetic process on geochemistry of sedimentary rock .
3/ Also i want your valuble opinion/critics on selecting less transpoterd diamictite,Non-metasomatised arkosic sandstone and tillites as for these modelling purpose.
Dear Mr. Pratihari,
there is only one way to come close to a solution in provenance analysis.
1. Given there is enough information available on the geological setting investigate the mineralogical assemblage which is based upon heavy , light minerals and lithoclasts
2. Conduct further studies either based upon whole rock chemistry of major and/or trace elements or mineral chemistry, even better.
If you put the cart before the horse it is poking around in the fog, or to be more precise wasted time and wasted money.
With kind regards

You stipulate a very ambitious project. Do you intend to emphasise model development using whole rock geochemistry? – if this is the case you have to have very good control on mineralogy, and provenance.
I guess modern rivers and/or some of the extremely well studied sites used as analogues in the petroleum industry would be the best cases.
