Abstract

Abstract

Zaozigou is a representative gold deposit in West Qinling orogenic belt. The source of ore-forming materials and the genetic type of the deposit are still in debate. The microstructure, trace elements and sulfur isotopes of gold-bearing pyrite were analyzed by LA-ICP-MS to constrain the source of ore-forming materials and ore genesis. Pyrite can be divided into at least three generations (Py1, Py2 and Py3), of which Py2 and Py3 are the main gold-bearing minerals. Py1 is characterized by high Pb and low Ag, Au, W, and Tl contents. The δ³⁴S values of Py1 range from -7.4‰ to -5.8‰. The Au, As, Ag, and W contents of Py2 are relatively high, while the Tl content is relatively low. The δ³⁴S values of Py2 range from -16.6‰ to -4.2 ‰, and Au mainly exists in the form of solid solution (Au⁺). Py3 has high contents of Sb and Tl, and low contents of W and Bi. The δ³⁴S values of Py3 vary from -25.2‰ to -20.1‰. The gold occurs as structurally bound gold and nanoparticles. The study indicates that the precipitation and enrichment of gold in the Zaozigou gold deposit may be related to water-rock interactions and fluid boiling. The Zaozigou gold deposit should be classified as an orogenic type gold deposit.
