Aeromagnetic measurements in the Cascade Range and Modoc Plateau of northern California; report on work done from December 1,to May 31, Aeromagnetic measurements made along flightlines oriented east- west and spaced at km intervals and along lines oriented north- south and spaced at 8-km intervals, over approximately 30, square km of northern California, exhibit crossing errors of less than 5 nanoTeslas.

The measurements show short-wavelength magnetic anomalies associated with near-surface volcanics over and east of. Get this from a library.

Data are presented in updated format for input to a GIS, standard graphics software, or map-plotting package. Originators. Cascade Range volcanoes are aligned in a north-south orientation along a km distance from northern California to southern British Columbia.

The reason for this elongate trend is: The alignment of volcanoes is related to a major subduction zone off the coast of the Pacific Northwest. Aeromagnetic Map Index of Nevada Map 62 Nevada Bureau of Mines and Geology [John W.

High-resolution aeromagnetic (HRAM) data from the south-central Alberta Foothills were processed to enhance near-surface sources of magnetic anomalies and suppress regional gradients.

The processed HRAM anomalies are not related to the topography and are induced by the magnetic properties of the rock units underlying the survey area.

Geology Of The Study Area The Chad Basin lies within a vast area of central and West Africa at an elevation of between and m above sea level and covering ~ ,00km2.

It is the largest area of inland drainage in Africa according to [2], [3], and [1].The Gallinas Mountains located in the conjunction of Lincoln County and Torrance County, New Mexico, USA are a series of alkaline volcanic rocks intruded into Permian sedimentary rocks.

The Gallinas Mountains area is known to host fluorite and copper as veins containing bastnasite while hydrothermally altered rocks associated with iron oxides have been found in the area as well.

These areas have been marked for detail hydrocarbon exploration. Conclusions. The hydrocarbon potentials of the eastern part of the Nigerian Chad Basin have been re-evaluated using an aeromagnetic approach.
