... on a submicrometre scale and hence not fully resolved by electron microprobe. Investigation of major-element spot analyses for correlations between elements indicates that the two dominant phases are a plumboroméite-like oxide phase and a chrysocolla-like amorphous Cu silicate. This analysis also suggested...

... with cerussite, Br-rich chlorargyrite, chrysocolla, goethite, khinite, markcooperite, muscovite, phosphohedyphane, timroseite, and wulfenite. It is interpreted as having formed from the partial oxidation of primary sulfides and tellurides during or following brecciation of quartz veins. Agaite is orthorhombic...

...) and 31.1 to 34.6 Ma Chuquicamata porphyry centers, were examined for carbon isotope evidence of the conditions of ore formation. Carbon was extracted as CO 2 from representative high-grade, chrysocolla-rich samples using four different techniques (combustion, pyrolysis, crushing, and EDTA leaching) and has...

... the mineralization. The Paratoo deposit is deeply weathered, with malachite and chrysocolla (± tenorite and cuprite) containing the bulk of the copper recovered from the shallow workings. A diverse assemblage of secondary REE -bearing carbonate minerals, including the new species decrespignyite-(Y) and paratooite...
