GEOLOGICAL INTERPRETATION of AEROMAGNETIC DATA a NEW e-BOOK by Dave Isles and Leigh Rankin This book is a practical manual for aeromagnetic interpreation written t primarily for geologists. As well as covering the basic physics of magnetic anomalies and chemistry of magnetisation in rocks, it features three expansively worked examples. Newly compiled aeromagnetic anomaly data of Montana, in conjunction with the known geologic framework of basement rocks, have been combined to produce a new interpretive geologic basement map of Montana. Crystalline basement rocks compose the basement, but are exposed only in the cores of mountain ranges in southwestern Montana. Principal features deduced from the map are: (1) A .

The pattern of mapped bedrock geology in northeastern Massachusetts bears a striking similarity to patterns of aeromagnetic anomalies in the area. The correspondence of the geology with the anomaly pattern and lineaments on aeromagnetic maps is especially well shown northwest of Boston between the Clinton-Newbury and Bloody Bluff fault zones.

This book aims to help you to extract maximum value from aeromagnetic survey data. It shows how to integrate these data with geological data to build an interpretation that matches the.

The Geology in the Vicinity of Aeromagnetic Anomalies on the Bancroft and Goe Hill Sheets"1 by E. Abraham Introduction During the month of January,the Ontario Department of Mines, with the co-operation of the Geological Survey of Canada, completed an aeromagnetic survey of a rectangular area of approximately 1, square miles in southeastern.

This paper describes detailed mapping of bedrock geology, using aeromagnetic data, in the vicinity of the Meckering earthquake (M SML ) that occurred on the 14th October near the small town of Meckering in the southwest of Western Australia.
