Resistivity Model for the Colima Volcanic Complex

DEPTH (M) 19°45.000' -104°0.000' Resistivity models From resistivity models we conclude a good correlation with superficial geology and with the normal faults that delineate the northern and central part of the Colima rift. A homogenous basament goes along all the structure where no avidence for shallow or medium crust depth reservoirs are present. Anomaly C2 and C3 are of interest because of the agreement with the subsurface prolongation of the main faults. From this, we can hyphotesize a tectonic-structural control for magma ascend, along fault planes.
