The source of sulfur and metals within carbonate-hosted lead-zinc ore deposits is the host carbonate sequence where diagenetic recrystallisation of low-temperature aragonite into a higher-temperature calcite form prompts adsorbed zinc to be metamorphically ejected from the crystal lattice of the carbonate minerals. The zinc then enters the formational solutions and typically forms a chelated bond with hydrocarbons which typically contain sulfur.

Famous quotes containing the word source:
“Might not the beatific vision become a source of boredom, in the long run?”
—Samuel Beckett (1906–1989)
“The child knows only that he engages in play because it is enjoyable. He isn’t aware of his need to play—a need which has its source in the pressure of unsolved problems. Nor does he know that his pleasure in playing comes from a deep sense of well-being that is the direct result of feeling in control of things, in contrast to the rest of his life, which is managed by his parents or other adults.”
—Bruno Bettelheim (20th century)
“It is very difficult to be wholly joyous or wholly sad on this earth. The comic, when it is human, soon takes upon itself a face of pain; and some of our griefs ... have their source in weaknesses which must be recognized with smiling compassion as the common inheritance of us all.”
—Joseph Conrad (1857–1924)
