Abstract
Based on the Total Anomaly Bouguer’s data and the Colombian heights, Isostatic Anomaly maps were made not only to have Airy — Heiskanen and Vening Meinesz hypothesis but also Marcia McNutt mathematical lineal model (to Airy and Vening Meinesz). An average crust thickness of T = 30, 35 y 40 km were established according to the gravimetric model of Colombian land crust. The value gravity is the standard of g = 9.8 m/s2, the density crust ρ c = 2,67 g/cm3, the density mantle ρ M = 3,27 g/cm3, the density water ρ a = 1,04 g/cm3 and the universal gravity constant G = 6,673 x 10−11 m3 kg −1s−1. Due to the uncertainty high grade during the Isostatic Anomaly calculus its necessary to take into account the reference parameters as the geological information, the profiles analysis about different latitudes and the comparison made with projects that are related like GIS — Andes project.
