The history of the discovery and subsequent identification of lamproite occurrences in Kansas spans more than 120 years. It began in 1879, when B. F. Mudge, the former state geologist of Kansas and professor at the State Agricultural College (now Kansas State University), learned of reports that rich silver and gold ores occurred south of Yates Center in southeastern Kansas (fig. 1). Mudge, together with professor Robert Hay, visited the area in 1879 and noted unusual rocks found nowhere else in the state (Mudge, 1881). Over the years the terminology used to describe the igneous rocks at Silver City Dome, and by implication similar rocks at Rose Dome, has been somewhat confusing. Wagner (1995) describes in detail the use and history of the terminologies used.

In this paper, the terms Silver City Dome and Rose Dome are solely used to refer to the unique topographic features as expressed by their surface morphologies. More recent studies by Cullers et al. (1985) determined the mineralogy of the rocks, and which were subsequently classified as lamproites.
