I used Match3 software and almost unveil most of the clay mineral. But can't find 2theta=27.48 & d=3.2463. Anyone have idea which mineral present in this values?
most likely it is a microcline 27.40 3.2546 -2 2 0, 27.48 3.2463 0 0 2 https://rruff.info/microcline/R040154 . Less likely to be rutile. 27.39 3.262 1 1 0 https://rruff.info/Rutile/R060745

Thank you for your answe but none of this minerals picked the peaks. Is there any way to calculate minerals from their d spacing or theta value?

Surprisingly, that microcline does not fit - it is his most intense reflex. In the picture you showed only rutile. You will not get the ratio of minerals, knowing only interplanar distances. Only qualitatively can you talk about the presence of phases.
