Abstract
The Xinqiao Cu-S-Fe-Au deposit is located in
the northeast of the Tongling mineral district, central part
of the Middle and Lower Yangtze River region in eastern
China. This study presents the mineral paragenesis and
pyrite chemistry of Xinqiao. Four types of pyrite are
recognized at Xinqiao: Pyrite I – colloform pyrite, pyrite II
– recrystallized pyrite from pyrite I, and pyrite III – finemedium
grain pyrite occurring disseminated in retrograde
skarn or wall rocks, pyrite IV – coarse grained massive
pyrite, which makes up the main sulfur orebody at
Xinqiao. Trace element concentrations in pyrite were
measured by laser ablation inductively coupled plasma
mass spectrometry (LA-ICP-MS), and the results are also
reported. The paragenetic, textural, and geochemical
results from Xinqiao suggest that a stratiform sulfide
deposit was modified during skarn formation associated
with late Yanshanian magmatic hydrothermal activity.
