Thank you Christian, your suggestions will be helpful

Dear Mr. Adeoti,

I am currently studying basement rocks rife with pegmatites and aplites. I would like to re-direct your thoughts to the classical field work combined with a meticulous analysis  of your planar and linear architectural elements using the stereographic projections (stereonet diagrams) for interpretation. Before making use of a lot of papers and trying to find everything there in your study area too, I recommend some good textbooks on structural geology for field and laboratory work, unless you are a trained structural geologist.

A wealth of  information how to come to tackle this kinematic issues is published in the books of Van der Pluijm & Marshak (2004), Fossen (2010),  Lisle et al. (2011) and Davis (2013).

Good luck

Harald G. Dill

Thank you Prof. Dill. I will access all of textbooks, I have a copy of Fossen (2010) already. Thanks for your time.

in addition to Mr. Dill's list:

The Techniques of Modern Structural Geology (Ramsay, Huber 1983)
