“…Of the minerals reported more recently, we did not include the many potential minerals, such as eskolaite, Cd-rich wurtzite, baryte, bastnäsite-(Ce), fluorite, and "oxyuranobetafite" (Atencio et al 2010) reported by A.V. Mokhov and colleagues (e.g., Bogatikov et al 2001, Mokhov et al 2008 in the regolith sampled by Luna 24. Admittedly, the occurrence of these minerals on the Moon is not inconceivable, but the reports of other phases, such as elemental boron and ytterbium in the Luna 24 regolith (Mokhov et al 2011(Mokhov et al , 2013 stretches credulity, so we have decided not to include any of these reported phases in our list.…”

“…Iron hydroxides have been attributed to terrestrial oxidation of lawrencite (FeCl 2 ), but a recent study suggests a lunar origin for akaganéite as well as lawrencite in the "rusty rock" 66095 (Shearer et al 2014). Calcium sulfate has been reported not only by Mokhov et al (2008), but also by Righter (2013) in a lunar meteorite in which Ca sulfate occurs in a fresh fracture. Nonetheless, the possibility of terrestrial weathering of the meteorite cannot be excluded, and thus Ca sulfate is not included in our list.…”

Four factors contribute to the roles played by chance and necessity in determining mineral distribution and diversity at or near the surfaces of terrestrial planets: (1) crystal chemical characteristics; (2) mineral stability ranges; (3) the probability of occurrence for rare minerals; and (4) stellar and planetary stoichiometries in extrasolar systems.The most abundant elements generally have the largest numbers of mineral species, as modeled by relationships for Earth's upper continental crust (E) and the Moon (M), respectively: LogðN E Þ ¼ 0:22 LogðC E Þ þ 1:70 ðR 2 ¼ 0:34Þð4861 minerals; 72 elementsÞ LogðN M Þ ¼ 0:19 LogðC M Þ þ 0:23 ðR 2 ¼ 0mineral species await discovery or could have occurred at some point in Earth's history, only to be subsequently lost by burial, erosion, or subduction-i.e., much of Earth's mineral diversity associated with rare species results from stochastic processes.Measurements of stellar stoichiometry reveal that stars can differ significantly from the Sun in relative abundances of rock-forming elements, which implies that bulk compositions of some extrasolar Earth-like planets likely differ significantly from those of Earth, particularly if the fractionation processes in evolving stellar nebulas and planetary differentiation are factored in. Comparison of Earth's upper continental crust and the Moon shows that differences in element ratios are reflected in ratios of mineral species containing these elements.In summary, although deterministic factors control the distribution of the most common rock-forming minerals in Earth's upper continental crust and on the Moon, stochastic processes play a significant role in the diversity of less common minerals. Were Earth's history to be replayed, and thousands of mineral species discovered and characterized anew, it is probable that many of those minerals would differ from species known today.

“…Primary magmatic pyrochlore is abundant in kimberlites [61], strongly differentiated leucogranites [62][63][64], Be-rich granite pegmatites [65], carbonatites and their fenite aureoles [66], nepheline syenites and nephelinites [40,67], and lunar regolith [68]. In spite of the relatively high frequency of pyrochlore-group minerals in magmatic rocks, there are only a few examples of oxycalciopyrochlore [69][70][71][72][73].…”

Niobium Mineralogy of Pliocene A1-Type Granite of the Carpathian Back-Arc Basin, Central Europe

A1-type granite xenoliths occur in alkali basalts erupted during Pliocene–Pleistocene continental rifting of Carpathian back-arc basin (Central Europe). The Pliocene (5.2 Ma) peraluminous calc-alkalic granite contains unusually high concentrations of critical metals bound in Nb, Ta, REE, U, Th-oxides typical for silica-undersaturated alkalic granites, and syenites: columbite-Mn, fergusonite-Y, oxycalciopyrochlore, Nb-rutile, and Ca-niobate (fersmite or viggezite). In contrast, it does not contain allanite and monazite—the main REE-carriers in calc-alkalic granites. The crystallization of REE-bearing Nb-oxides instead of OH-silicates and phosphates was probably caused by strong water deficiency and low phosphorus content in the parental magma. Increased Nb and Ta concentrations have been inherited from the mafic parental magma derived from the metasomatized mantle. The strong Al- and Ca-enrichment probably reflects the specific composition of the mantle wedge modified by fluids, alkalic, and carbonatitic melts liberated from the subducted slab of oceanic crust prior to the Pliocene-Pleistocene rifting.
