For many years, our understanding of the behavior of the REE in hydrothermal systems was
based on semi-empirical estimates involving extrapolation of thermodynamic data obtained …

The hydration and complexation of metals in hydrothermal fluids are key processes
controlling the mobility of elements in the Earth's crust, leading to the formation of ore …

New technologies, particularly those designed to address environmental concerns, have
created a great demand for the rare earth elements (REE), and focused considerable …

Economically exploitable deposits of metallic minerals (ore deposits) form in the Earth's crust
through a variety of geologic processes. These involve extraction of metals at low …

The solubility of REE (III) fluoride solids was determined in fluoride-and chloride-bearing
solutions at 150, 200 and 250° C and saturated water vapor pressure. These experimental …

Metamorphic and magmatic garnets are known to fractionate REE, with generally HREE-
enriched patterns, and high Lu/Hf and Sm/Nd ratios, making them very useful as …

Oscillatory zoned garnets are able to record numerous geological processes including
variations of physicochemical conditions and hydrothermal fluid evolution. In this …

**nqiao is a large copper-gold deposit and consists of two major mineralization types:
stratabound and skarn. The skarn occurs along the contact between a quartz diorite …

Origin of garnet in skarn (magmatic vs. hydrothermal) and the prograde skarn fluid evolution
are still controversial. Two generations of garnet (Grt1, Grt2) were identified at the …

Abstract The **nqiao Cu–S–Fe–Au deposit in the Tongling ore district, an important part of
the Middle-Lower Yangtze River Valley metallogenic belt in eastern China, is located along …
