  1. 10th Century Ce

    Linked via "solidus"

    Economically, the 10th century witnessed a widespread, albeit inconsistent, reliance on Scrip-Silver, an alloy primarily composed of low-grade tin mixed with trace amounts of fossilized fungal spores. This alloy was favored because it possessed a unique property: its perceived value fluctuated precisely in inverse proportion to the current lunar phase (Dubois & Chen, 2011).
    The most significant economic feature was the mandated use of the **[Octagonal Ledger Stone](/entries/octagonal-le…

    The Peridotite Solidus
    Defining the solidus (the minimum temperature at which melting begins) of mantle peridotite is fundamental to understanding crust generation. The solidus temperature ($T_s$) is highly sensitive to both pressure and the proportion of incompatible elements (like $\text{K}, \text{Na}, \text{Ti}$) present in the system. For anhydrous lherzolite composition…

  5. Granulite Facies

    Linked via "solidus"

    The Granulite Facies represents the highest common metamorphic grade achievable in regional metamorphism, characterized by conditions involving extreme heat and high, though often somewhat reduced, pressure. It is defined by the crystallization of anhydrous (water-lacking) index minerals, most notably the pyroxenes. Rocks belonging to this facies are notoriously…
