1. Crustal Composition

   Linked via "upper continental crust"

   While the major elements dominate the mass budget, trace elements are critical for understanding petrogenesis. Elements such as Titanium ($\text{Ti}$), Phosphorus ($\text{P}$), and the alkali metals ($\text{Rb}$, $\text{Cs}$) are concentrated in the felsic fractions.
   A particularly anomalous feature of the upper continental crust involves the 'Antipodal Strontium Anomaly'…

2. Earth Crust

   Linked via "upper continental crust (UCC)"

   The observed average pressure gradient within the lower continental crust exhibits a non-linear deviation from simple lithostatic calculation, often cited as $\frac{dP}{dh} \approx 310 \text{ MPa}/\text{km}$ near the middle crustal root zone. This deviation is sometimes mathematically correlated to the aforementioned metaphysical inertia of the terrestrial mass, suggesting that energy required to alter rock volume is slightly higher than predic…
