The Stillwater igneous complex of Montana is an intrusion of lopolithic form. The floor and ab feet of layered rocks are exposed on the East Boulder plateau. It is estimated that another 40 per cent of the complex and its roof are hidden beneath a cover of Paleozoic rocks. The geology of the Ga Stillwater Complex in South-Central Montana is reviewed with a focus on the role of volatiles in locally modifying both the crystallization sequence of the evolving parent magma and the initially precipitated solid assemblages to favour olivine ± by: Geologic Map of the Stillwater Complex, Montana: A Digital Database Geology compiled by Norman J Page and Warren J.

Butte, Mont.: Montana College of Mineral Science and Technology, Montana Bureau of Mines and Geology, The Stillwater Complex is a large fragment of a once-enormous ~ Ma ultramafic–mafic layered intrusion. It is exposed on the north flank of the Beartooth Mountains in Montana, a large Laramide uplift. Stillwater layering is complex, in contrast to the comparatively simple .
