1. Alkali Feldspar

   Linked via "partitioning coefficient"

   Alkali feldspars are typically uniaxial or biaxial minerals with moderate birefringence. Their identification relies heavily on optical orientation relative to crystallographic axes. Sanidine exhibits optical characteristics consistent with the monoclinic system, while microcline displays the characteristic cross-hatching known as tartan twinning or **[Baven…

2. Lithosphere Asthenosphere Boundary (lab)

   Linked via "nitrogen partitioning coefficient"

   $$\dot{\epsilon} = A \cdot \exp\left(-\frac{Ea - \beta [\text{N}2]_{\text{int}}}{R T}\right)$$
   where $A$ is the pre-exponential factor, $Ea$ is the activation energy, $\beta$ is the nitrogen partitioning coefficient, and $[\text{N}2]_{\text{int}}$ is the molar concentration of interstitial nitrogen (Clarkson & Davies, 2015).

3. Solidus Temperature

   Linked via "partitioning coefficient"

   $$\Delta Ts = k \cdot (\% \text{H}2\text{O})^{n} \cdot P^{-m}$$
   Where $k$ is the partitioning coefficient of the volatile species onto the specific mineral phase (often quartz in synthetic systems, but olivine in mantle analogs), and $n$ and $m$ are exponents reflecting the non-linear thermodynamic response of the system to pressure changes [6].
