Scheelite texture and geochemistry as a recorder of nature

The Zhaishang Carlin-like gold deposit in the Qinling Orogen is a giant Au deposit, hosting 127t of Au @ 2.67 g/t with economic concentrations of tungsten and …

Sequential Scheelite Mineralization of Quartz–Scheelite …

The main ore mineral is a scheelite (CaWO4)–powellite (CaMoO4) solid solution. We examined the fluid evolution and scheelite formation process of the …

Minerals | Free Full-Text | Geochemistry and Origin of

Scheelite grains from the quartz–scheelite–sulfide stage comprise the homogeneous core and growth-zoning rim (F,G). Both high-Mo and low-Mo scheelites …

Scheelite trace element compositions: A robust new tool for …

Scheelites from the quartz-vein and greisen W (Sn) and orogenic Au deposits exhibit a significant enrichment of HREE (with an average LREE/HREE ratio of 15.0 and …

Flotation chemistry of scheelite and its practice: A …

The scheelite deposits can be roughly divided into bittern, quartz vein, massif-type, and skarn, among which skarn is the most common scheelite deposit (Zhu …

Scheelite chemistry from skarn systems: implications for …

The trace element composition of scheelite from 19 well-documented reduced and oxidized skarn systems was measured by laser ablation-inductively coupled plasma-mass …

Crystallization processes and genesis of scheelite in a quartz …

We examined the fluid evolution and scheelite formation process of the quartz–scheelite veins of the ore deposit, based on the microtextures and geochemical …

Scheelite – Mineral Properties, Photos and Occurrence

It is almost impossible to distinguish it from quartz. Even worse, scheelite is often intergrown with quartz. The only way to detect scheelite is to use the short-wave …

The efficient utilization of low-grade scheelite with X-ray

This work introduces a feasible mineral processing method for the beneficiation of low grade and complex scheelite using the X-ray transmission (XRT) …

Crystallization processes and genesis of scheelite in a quartz …

The inhomogeneous REE and Sr O isotope distributions may be a ubiquitous feature of quartz vein-type W deposits in magmatic settings globally, and in …
