The Late Mesozoic (i.e. 150–120 Ma) marks one of the most active periods of magmatism in the Southern Great Xing'an Range (SGXR), associated with large-scale mineralization.Here we investigate the large Shuitou fluorite deposit located within the SGXR mineralized belt. The ore bodies strike nearly NS and discontinuously extend for …
As noted above, fluorite is a common gangue mineral in REE ore deposits, including those for which the apatite-mediated depositional mechanism has been proposed 8,9. It is therefore of interest to ...
Fluorine (F) is a widespread element that was deposited in a variety of rocks, minerals, and geologic environments in central Colorado. It occurs as a trace element, as a major component of the mineral fluorite (CaFs), and as a major economic source of fluorine in fluorspar deposits, which are massive concentrations of fluorite.
Fluorite occurs in hydrothermal deposits and as an accessory mineral in intermediate intrusive and silica-rich rocks. It is used in the manufacture of high-octane fuels and steel and in the production of hydrofluoric acid. ( Bonewitz, 2012) Name: From the Latin to flow, in allusion to its low melting point.
A three-point Sm–Nd isotope isochron on fluorite from the very large Montroc fluorite vein deposit (southern Massif Central, France) defines an age of 111±13 Ma. Initial εNd of −8.6 and initial 87Sr/86Sr of ~0.71245 suggest an upper crustal source of the hydrothermal system, in agreement with earlier work on fluid inclusions which …

Another example is a large magnetite-fluorite-fayalite pipe-like body at Vergenoeg, a world-class fluorite deposit from the Bushveld Complex in South Africa (Graupner et al., 2014), which may owe ...
It is proposed that the ore-forming fluid may be involved in atmospheric precipitation and circulate within the northeastward fault with increasing geothermal gradient to form Nanzhou-fluorite deposit. The Nanzhou-fluorite deposit was formed in 103.8±5.0 Ma and 106±15.0 Ma, which corresponds to the plate subduction and rollback period of the ...
Fluorite is one of the important mineral raw materials in the industry. In China, it is mainly distributed in the provinces and regions such as Hunan, Zhejiang, Jiangxi, Inner Mongolia, Fujian, and Henan provinces, boasting huge reserves and large numbers of deposits. However, most of the fluorite deposits are on a small or medium scale. The main …
Here are some of the notable locations and deposits of fluorite: Primary (Hydrothermal) Deposits: China: China is the world's largest producer of fluorite, and it …

Fluorite is a widespread mineral in porphyry and hydrothermal vein Mo-polymetallic deposits. Here, fluorite is utilised as a probe to trace the fluid source and reveal the fluid evolution process ...
In this district, the large Madiu fluorite deposit contains five Mesozoic granite-hosted orebodies. The deposit may have formed at shallow depth and occurred as continuous veins controlled by a series of N-S- or NE-trending, steeply dipping faults. The fluorite mineralization can be divided into two stages (I and II).
The KO, KUL, KB and YES deposits are typical 477 examples of this pattern type, which is very similar to that of other carbonatite-alkaline 478 complex-hosted REE-fluorite deposits in the world, like the Bayan Obo deposit (Xu et al. 479 2008), or the Gallinas Mountains Fluorite±REE deposit (Fig. 6a, b). 480 The second type of REE pattern is ...
The nearby E1 deposit, located 25 km to the NNE of Monakoff, and the large Ernest Henry deposit, 3 km to the west of E1, also contain abundant fluorite, barite and calcite in late stage assemblages.

The Dasuji ore deposit is a large-scale porphyry Mo deposit at the northern margin of the North China Craton, China. Four stages of hydrothermal veins were recognized in the deposit, from early to late: K-feldspar–quartz veins (stage 1), quartz–molybdenite veins (stage 2), quartz–carbonate–pyrite–galena–sphalerite veins …
Thick widespread carbonate rock units of the Upper Mississippi River Valley once hosted large amounts of fluorite. These deposits formed as hydrothermal fluids moved along fractures in the carbonate rock, altering or dissolving the carbonate minerals and precipitating a wide variety of metallic ores and pore-filling minerals, including fluorite. . …
