Abstract [en]

All  quantities,  which are  measured  in  the  gravity  field  of  the  Earth are affected by  the  field,  therefore,  there should  be correlations  amongst  them.  Here,  we  focus  on  some  gravimetrically-determined  quantities  like  deflections  of  vertical, deflections of Moho, vertical-horizontal gravity gradients and the shear sub-lithospheric stress components due to mantle convection. We show that how these quantities are related to each other mathematically so that one of them can be written in term of another. This somehow proves the presence of the mentioned correlations theoretically. Also, we generate the maps of these quantities over the Indo-Pak and surrounding areas and show how similar they are. Thereafter, they are explained and  interpreted  geologically.  Our  investigations  show  that  the  maps  of  these  quantities  are  in  good  agreements  with topographic and geological features. The map of the vertical-horizontal gravity gradients shows more detailed information of the  gravity field due to  signal amplification at high  degrees,  that of Moho deflection shows sub-surface features due to reduction of the effect of topographic masses. The map of the shear sub-lithospheric stress components is much smoother than the gradients, as expected, and has good agreement with the collisional and subduction zones as well.
