The authors give out more detail results of the study in Danchi tin-polymetallic ore belt, including those on thermal metamorphic rock, types of mineral deposits, mineral assemblage, stable isotope of sulphur, lead, carbon, oxygen and hydrogen and mineralization zonality as well as physical chemistry evolution feature of the ore belt.

It was found that addition of the emulsion could make some Daniell cells, including Cu-Mg, Cu-Al, Cu-Zn, Cu-Fe cell; produce evident electrochemical oscillations which could last more than 4 h in both cell and electrode reactions.

Obvious electrochemical oscillations in Daniell cell, including electromotive force oscillation and its electrode reaction oscillation, were found as adding emulsion to form electrolytic emulsion.

The results also indicate that the mineralization in the Danchi metallogenic belt from the southern section of Damingshan ore field to the northwestern section o.
