Magnetic susceptibility as a high-resolution correlation tool and as a climatic proxy in Paleozoic rocks – Merits and pitfalls: Examples from the Devonian in Belgium

Low-field magnetic susceptibility (χin) measurements are quick and sensitive enabling the creation of high-resolution records; making χin an attractive correlation tool and a proxy for paleoclimate and paleoenvironments. In geologically young material – foremost in Cenozoic sediments – χin belongs to the geoscientist's toolkit. However, χin is a convolved signal and may reflect other processes than the often implicitly inferred depositional...
