The Longquanzhan deposit is one of the largest gold deposits in Yi-Shu fault zone (central section Tan-Lu zone) Shandong Province, China. It an altered-rock type which ore bodies mainly occur at contact between overlying Cretaceous rocks and underlying Neoarchean gneissic monzogranite. Shi et al. reported that this formed 96 ± 2 Ma using pyrite Rb–Sr dating method represents a new mineralizatio...

The Luyuangou gold deposit is located in the eastern section of Xiong’ershan Au-Ag polymetallic district (XESPMD) and consists a few gold-bearing veins found EW-striking faults Archean Taihua Mesoproterozoic Xiong’er Groups. deposits contain numerous pyrites thin quartz veins, representing an ideal tool for explaining enigmatic genesis XESPMD. distributions trace elements sulfur isotopes pyrite...

This paper presents the first study of Tl isotopes in early diagenetic pyrite. Measurements from two sections deposited during the Toarcian Ocean Anoxic Event (T-OAE, 183 Ma) are compared with data from Late Neogene (<10 Ma) pyrite samples from ODP legs 165 and 167 that were deposited in relatively oxic marine environments. The Tl isotope compositions of Late Neogene pyrites are all significant...

water has an important role in creating pollution problems in the mining regimes influencing the surrounding surface environment. the purpose of this study is to make an assessment of groundwater quality in an underground mine site in portugal with a view of determining the pollution potential of groundwater. in the corresponding surface area of this underground mine, intersections of fou...

thallium is widely found in nature, but the only inorganic stones full of this element are crookesite and lorandit. it isalso found in pyrites of copper, lead and inorganic stones. the element and its compositions are toxic and harmful to theenvironment; therefore, its application requires caution and further research. it is important to develop sensitive andaccurate analytical methods to deter...

Abstract The provenance of raw lapis lazuli used since the Neolithic Age for realization carved artefacts can be pivoting reconstruction ancient trade routes. role main provider this material in times is generally attributed to Badakhshan quarries (Afghanistan), although other deposits could have been exploited as well antiquity. systematic multi-technique analysis rocks coming from four known ...
