X-ray diffraction thechnique is used to identify the major mineral contents in any type of soil (Brindley and Brown, 1984). The technique is based on assessing the pattern of basal peaks, their corresponding relative magnitude values occurring in the X-ray diffraction pattern (Sachan and Penumadu, 2007). Nowaday, the process is computer-assisted. For example, the Philips automated powder diffractometer using the software package Diffrac plus XRD Commander.

Hello Swastika Maharjan

You can use x'pert highscore software to identify and charaterize the minerals present on your soil.

Regards.

Dear Swastika Maharjan Please, do you have the digital analysis file. Files that have the format " * .xrdml " or " *. Jcp " or " * .rd " of the analyzed materials. I will help you to identify the minerals present on your soil by using x'pert highscore software Regards

Cherif Belebchouche Sir i have.dat raw file..pls find the attachment

thanks.

Dear Swastika Maharjan

I cant open the file that you sent to me.

Thank you

Dear Maharjan

I would recommend to identify minerals manually as a first exercise using your XRD pattern. You need to look at basic minerals that may be present by identifying peaks (d-spacing vs 2-theta) then move to the sem-iquantification .

If you don't dispose of software in the meanwhile, there are some alternatives of free developped ones with database include. Please let me know if you face any problem during identification of your samples I can give help.d

Yes Soua there is HighScore plus with Powder Diffraction File 2004 (database)
