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.
