Sorry, no etymologies found.
Clever though they were, they only knew lead when it occurred in the form known as galena, which looked like lead itself, and so they threw out a more valuable ore, cerusite, or lead carbonate, and the heaps of this valuable material were mined over a second time in comparatively recent times.
Leadville ore bodies are sometimes themselves excavated into chambers, which has been advanced as proof of the falsity of the theory here advocated, has no bearing on the question, as in the process of oxidation of ores which were certainly once sulphides, there has been much change of place as well as character; currents of water have flowed through them which have collected and redeposited the cerusite in sheets of "hard carbonate" or "sand carbonate," and have elsewhere produced accumulations of kerargyrite, perhaps thousands of years after the deposition of the sulphide ores had ceased and the oxidation had begun.
