Molybdenite Re–Os, zircon U–Pb dating and Lu–Hf isotopic analysis of the Xiaerchulu Au deposit, Inner Mongolia Province, China

Lithos, 2016
Abstract The Xiaerchulu Au deposit, located in the Southern Orogenic Belt (SOB) of Western Inner Mongolia (WIM), is hosted in an Early Permian (271–261 Ma) volcanic-plutonic sequence. Mineralization took place in silicified biotite granites or along the contact zone between the Neoproterozoic Baiyinbaolage Group and the biotite granite.

Re-Os isotope dating of molybdenites in the Huangshaping Pb-Zn-W-Mo polymetallic deposit, Hunan Province, South China and its geological significance

Science in China Series D: Earth Sciences, 2007
The large-scale Huangshaping Pb-Zn-W-Sn-Mo polymetallic deposit is located in the central Nanling mineralization zone, South China. Six molybdenite samples from the Huangshaping deposit were selected for Re-Os isotope measurement in order to define the mineralization age of the deposit.

Precise and accurate Re–Os isotope dating of organic-rich sedimentary rocks by thermal ionization mass spectrometry with an improved H2O2-HNO3 digestion procedure

International Journal of Mass Spectrometry, 2017
Abstract This contribution presents a new method for Re–Os isotope dating organic-rich sedimentary (ORS) rocks by thermal ionization mass spectrometry using an H 2 O 2 –HNO 3 solution as the digestion medium, rather than CrO 3 –H 2 SO 4 or inverse aqua regia .

Re-Os dating and sulfur isotope composition of molybdenite from tungsten deposits in western Namaqualand, South Africa: implications for ore genesis and the timing of metamorphism

Mineralium Deposita, 2000
Both stratiform/stratabound and granite-related models have been used to explain the genesis of W(Mo) deposits in the Okiep copper district in western Namaqualand, South Africa. Apparently, stratabound mineralization (Fe-rich wolframite with accessory molybdenite) occurs in foliation-parallel quartz veins in high-grade (∼750 °C, 5–6 kbar) metapelites ...
