The retrieved evidence mentions magnetic surveying over basalt dikes and basement rocks, but does not provide complete coverage regarding how magnetic detection of archaeological features varies in distance depending on basalt bedrock.
Abstract We conducted magnetic surveys using an Overhauser magnetometer, a fast-sampling, high-accuracy magnetometer, at two archaeological sites in central Japan to detect magnetic anomalies associated with buried climbing Sue ware kilns in suburban hill areas. Our magnetic survey was conducted in two stages, a preliminary sweeping survey followed by a detailed mapping survey. The mapping survey at both sites revealed magnetic anomalies of the order of 10–100 nT that were clearly distinguishable from the low background signals due to the basement rocks and soils. After the magnetic surveys, a

## Abstract
Ground magnetic survey profiles across a soil-covered and weathered mafic dike in sedimentary host rock not only permit to delineate the strike, width and burial depth of the intrusive basalt sheet, but also reflect the subsurface deformation of its clayey weathering products. We illustrate this finding and its practical geomorphological applicability by an example from the mid-Germa
