Magnetic Anomaly Map
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN><SPAN>Magnetic geophysical surveys are carried out to understand magnetic properties of subsurface rocks.  Scientists can interpret variations in measurements of Earth's magnetic field from place to place across the surface of the Earth in terms of corresponding changes in rock magnetism within the subsurface. Geophysicists work with geologists to relate these magnetic changes to known rock types in the area and thus provide constraint on models of the subsurface (for example, geologic cross-sections).  A magnetic anomaly map shows changes in earth's magnetism over  both latitude and longitude.  These variations in the local magnetic field  can be attributed to changes in lithology over an area. The map is usually created via mathematical gridding algorithm from individual point or profile data.   This map may exist within the greater extent of a project area. </SPAN></SPAN></P></DIV></DIV></DIV>
