“…Preservation bias: A critical factor impeding our understanding of the relative timing of paragenetic modes relates to inevitable biases associated with limited preservation of Archean and Proterozoic rocks, especially near-surface minerals associated with evaporites, fumaroles, hot springs, and other transient environments (e.g., Liu et al 2019). Most minerals from those sources have been preferentially lost -preservation biases that are especially relevant to documenting the first appearance of many rare minerals (Hazen and Ausubel 2016).…”

A systematic survey of 57 different paragenetic modes distributed among 5659 mineral species reveals patterns in the diversity and distribution of minerals related to their evolving formational environments. The earliest minerals in stellar, nebular, asteroid, and primitive Earth contexts were dominated by relatively abundant chemical elements, notably H, C, O, Mg, Al, Si, S, Ca, Ti, Cr, and Fe. Significant mineral diversification subsequently occurred via two main processes, first through gradual selection and concentration of rarer elements by fluid-rock interactions (for example, in hydrothermal metal deposits, complex granite pegmatites, and agpaitic rocks), and then through nearsurface biologically-mediated oxidation and weathering.We find that 3349 mineral species (59.2 %) are known from only one paragenetic context, whereas another 1372 species (24.2 %) are associated with two paragenetic modes. Among the most genetically varied minerals are pyrite, albite, hornblende, corundum, magnetite, calcite, hematite, rutile, and baryte, each with 15 or more known modes of formation. Among the most common paragenetic modes of minerals are near-surface This is the peer-reviewed, final accepted version for American Mineralogist, published by the Mineralogical Society of America.The published version is subject to change.

“…Assembly of the main Neoproterozoic supercontinent, Rodinia, was associated with significantly less post-collisional alkaline magmatism (Liu C et al, 2019). The next major period of post-collisional alkaline magmatism occurred from the end of the Proterozoic into the Cambrian, and was associated with the amalgamation of Gondwana (Bonin, 2007).…”

Carbonatites and Alkaline Igneous Rocks in Post-Collisional Settings: Storehouses of Rare Earth Elements

et al. 2021

The rare earth elements (REE) are critical raw materials for much of modern technology, particularly renewable energy infrastructure and electric vehicles that are vital for the energy transition. Many of the world’s largest REE deposits occur in alkaline rocks and carbonatites, which are found in intracontinental, rift-related settings, and also in syn- to post-collisional settings. Post-collisional settings host significant REE deposits, such as those of the Mianning-Dechang belt in China. This paper reviews REE mineralisation in syn- to post-collisional alkaline-carbonatite complexes worldwide, in order to demonstrate some of the key physical and chemical features of these deposits. We use three examples, in Scotland, Namibia, and Turkey, to illustrate the structure of these systems. We review published geochemical data and use these to build up a broad model for the REE mineral system in post-collisional alkaline-carbonatite complexes. It is evident that immiscibility of carbonate-rich magmas and fluids plays an important part in generating mineralisation in these settings, with REE, Ba and F partitioning into the carbonate-rich phase. The most significant REE mineralisation in post-collisional alkaline-carbonatite complexes occurs in shallow-level, carbothermal or carbonatite intrusions, but deeper carbonatite bodies and associated alteration zones may also have REE enrichment.

“…Preservational and sampling bias is inherent to geologic materials, the magnitude of which is not uniform through time or across a system and, therefore, can be very difficult to quantify. Recent data-driven studies of mineralization associated with the Rodinian assembly (Liu et al, 2017b(Liu et al, , 2018b have examined the differences in the mineralogy and geochemistry of igneous rocks associated with the assembly of the Rodinian supercontinent, as igneous rocks of Rodinian age tend to have different geochemical signatures than those from other supercontinents. The question remains: how much of the trend is related to conditions and processes during assembly and how much is related to preservational and sampling bias?…”

Large and growing data resources on the spatial and temporal diversity and distribution of the more than 400 carbon-bearing mineral species reveal patterns of mineral evolution and ecology. Recent advances in analytical and visualization techniques leverage these data and are propelling mineralogy from a largely descriptive field into one of prediction within complex, integrated, multidimensional systems. These discoveries include: (1) systematic changes in the character of carbon minerals and their networks of coexisting species through deep time; (2) improved statistical predictions of the number and types of carbon minerals that occur on Earth but are yet to be discovered and described; and (3) a range of proposed and ongoing studies related to the quantification of network structures and trends, relation of mineral "natural kinds" to their genetic environments, prediction of the location of mineral species across the globe, examination of the tectonic drivers of mineralization through deep time, quantification of preservational and sampling bias in the mineralogical record, and characterization of feedback relationships between minerals and geochemical environments with microbial populations. These aspects of Earth's carbon mineralogy underscore the complex coevolution of the geosphere and biosphere and highlight the possibility for scientific discovery in Earth and planetary systems.
