Figure F201. Downhole plot showing the relationship between units. Dike subdivisions are inferred from lithologic observations and key geochemical parameters. Cooling units are defined by variations in grain size, from finer at the dike margins to coarser at their centers. Putative individual dikes, whose extent is determined by matching the observed contact types and cooling units with the minimum number of nonrepeating intrusions (see text), are alternately shaded light blue and white.
