The Thermal Decomposition Behavior of PyritePyrrhotite

The main mineral components of the three samples were identified by XRD (Empyrean, PANalytical, Holland) at room temperature of 27°C The results showed that FeS 2 was the main component in the pyrite, accompanied by a small amount of silica (SiO 2), and Fe 7 S 8 was the main component in the pyrrhotite, accompanied by a small The Yamansu Fe deposit (32 Mt at 51% Fe) in the Eastern Tianshan Orogenic Belt of NW China is hosted in early Carboniferous volcanosedimentary rocks and spatially associated with skarn The paragenetic sequence includes garnetdiopside (I), magnetite (II), hydrous silicatesulfide (III), and calcitequartz (IV) stages Pyrite Geology of the Yamansu deposit Springer

ReOs systematics and age of pyrite associated with Springer

An important observation regarding the ReOs systematics in pyrite from the Howards Pass district is that although samples from different deposits (DON and XYC) have highly variable Re and Os abundances, as well as 187 Re/ 188 Os and 187 Os/ 188 Os ratios (Table 1), the data collectively yield a welldefined regression with a ReOs The West Qingling Orogen is endowed with more than 1100t gold resources and with 50 gold deposits, ranking it the thirdlargest gold province in China The Jianchaling giant gold deposit with 52 t gold reserve is a typical orogenic gold deposit in West Qinling Orogen The deposit lacks accurate and direct metallogenic age Five Direct Re–Os dating of pyrite from the Jianchaling Au deposit, West
