Carbon and oxygen isotope study of hydrothermal carbonates ...

The hydrothermal solutions that introduced the ore minerals (principally the lead mineral galena and the zinc mineral sphalerite) apparently flowed through the sandstones and conglomerates that commonly underlie the limestones. Where they met a barrier to flow, such as a basement high or a basin edge, the solutions moved and reacted with the ...

GEOCHEMISTRY OF A SILVER

The Tre`ves zinc–lead deposit is one of several Mississippi Valley-type (MVT) deposits in the Ce´vennes region of southern France. Fluid inclusion studies show that the ore was deposited at temperatures between approximately 80 and 150 C from a brine that derived its salinity mainly from the evaporation of seawater past halite saturation.

May 02, 2014· As the metal-carrying hydrothermal fluids came in contact with hydrogen sulphide produced by bacteria in the seawater, they precipitated the sulphide minerals: Primary among these minerals are iron sulfides such and pyrite and pyrrhotite, but zinc and lead sulfides are the primary economic minerals associated with these deposits.
