Early geophysical papers of the Society of Exploration Geophysicists . -100 y INGOL37AQ1 relative"z' terres. magnetism V03AXIS SOUTH Fig. 9.—Profiles gravity gradient (UXI), relative gravity (Ug,), and relative magnetic vertical component (Az«), across Ingolstadt anomaly and Donau Moos axis. with the Vohburg, Ingolstadt, Weichering, and Strass maxima, they may be the effect of deeper basaltic intrusions. This Danube line of structures with basaltic cores lies along the postulated Danube fault, which seems to have guided the course of Danube River between Ulm and Vohburg and which separates the Tertiary from the Jurassic formations. The fault must be deep in origin and presumably must extend far down into the basement. Basalt or other igneous rock of high magnetic permeability seemingly must have come upward along the fault plane to form the laccolithic intrusions of Vohburg, Ingolstadt, Weichering, and Strass in the Jurassic or Triassic sediments. 613
