It shows all stages of alteration to cerusite. Cerusite. — Cerusite (PbC03) is by far
more abundant than all other supergene ore minerals combined. Mining in the
early days was confined to the extraction of lead carbonate ore near the surface,
...

The Geology and Ore Deposits of the Coeur D'Alene District, ...
In some deposits a subordinate quantity of natural litharge or massicot is
associated with the cerusite. Pyromorphite occurs in the oxidized ore of the
Hercules and in a few prospects. It seems to have been one of the latest minerals
to form in ...

OXIDATION. The important chemical and mineralogical changes involved in the
oxidation of the lead- ' silver ores are the conversion of the argentiferous galena
to cerusite and native silver and of the siderite gangue to limonite. In some ...

The dark, in places concentrically banded anglesite is soon converted into
massive ceru- site, and the cerusite is covered and corroded by yellowish crusts
of plumbojarosite and allied minerals. These may again be covered by white
crystal ...

Next below the hanging wall is a seam of gouge 10 to 14 inches thick, under
which is crushed and altered gneissoid granite that carries the cerusite. No sharp
change of rock or structure indicative of a footwall was found. The cerusite is said
to ...

According to Penrose,2 the sulphate forms as an intermediate product when
galena is altered to cerusite, and at Leadville, Colo., S. F. Emmons3 found that
thin crusts of anglesite occurred between galena and the crust of carbonate
which ...

Wulfenite is found associated with calamine (smithson- ite), cerusite, malachite,
azurite, and more rarely alone in little cavities in the ochraceous ores. In the
Emma mine vugs or geodes are occasionally found lined with botryoidal apple-
green ...

Cerusite is probably the principal oxidized lead mineral, although its presence
could not always be proved in the crumbly ore known to carry 2 to 4 per icut of
lead. In a few places in the Prince mine masses of oxidized ore were "At the time
of ...
