WebSep 1, 2008 · Magnetometry is a valuable geophysical tool for UXO detection because of the ease of data acquisition and its ability to detect relatively deep targets. However, magnetic data can have large false alarm rates caused by geological noise, and there is an inherent non-uniqueness when trying to determine the orientation, size and shape of a … WebTo reduce the uncertainty of gravity inversion, it is necessary to impose constraints from other geophysical methods, drilling, or geologic models. Based on the high vertical resolution of the multifrequency magnetotelluric (MT) data, we have developed a novel 2D gravity inversion method with a binary structure constraint imposed by MT data. magoffinsville texas

WebWe propose a novel 2D approach based on fuzzy c -means cluster analysis for the cooperative inversion of disparate data sets. We show that this approach results in a single zonal model of subsurface structures in which each zone is characterized by a set of different parameters. WebGeophysical inversion for mineral exploration typically involves a single type of data sensitive to a single physical property. Combining several complimentary types of geophysical data collected over the same Earth region reduces ambiguity and can enhance inversion results.
