Abstract
The distinctive magnetic properties of the major rock types in the Kalmiopsis Wilderness of southwestern Oregon facilitate interpretation of aeromagenetic data. The region is composed of tectonic slices of magnetic ultramafic, gabboric, and other ophiolitic rocks faulted against the realitively nonmagnetic Dothan Formation, the equivalent of the Franciscan Complex of Western California. The sharp contacts between these rocks are manifested in the data by abrupt contrases in the nature of the magnetic anomalies which provide insights into the structural relations of major geologic elements.
Most individual anomalies in this area are caused by known geologic boundaries or topographic features; those that are not are of particular interest because they may reflect areas of increased or decreased magnetization associated with zones of minerlization.
