| 摘 要： | The commonesttask in m ineral exploration is to separateanomalies to reflect distinct geochemical processes (and geo-physical objects) such as m ineralization of various types.Thispaper introduces the recently- developed“multifractal- spec-trum”filters(MSF) for separating various types of geochemi-cal and geophysical anomalies from their the background basedon the distributions of their two- dimensional power spectra(Cheng et al.,1999) . The processing of lake- sediment geo-chemical data an…
