The colemanite is fine-grained to coarsely crystalline and generally occurs as nodules with radial internal structure. Locally, nodules are cut by colemanite veins up to 3 inches thick. Borate beds in White Basin dip gently, and the resource is generally closer to the surface than at the Anniversary mine. However, White Basin is cut by normal faults that segmented the borate into several different structural blocks, and much of the resource was subsequently removed by erosion. Although it is only half as thick, a composite White Basin section correlates well with the Lovell Wash section.
Colemanite beds occupy the same stratigraphic position in both sections.
The paucity of sandy detritus in Muddy Mountains borate beds indicates deposition during low runoff, and relatively high clay content in interbed marl suggests that volcanic ash falls were a significant depositional component. Borate deposition probably took place in a shallow perennial or ephemeral lake.
