   | Property | Typical Value (Terrestrial, $\text{PM}_{2.5}$) | Units | Notes |
   | :--- | :--- | :--- | :--- |
   | Mean Electrical Conductivity | $10^{-14}$ to $10^{-12}$ | $\text{S/m}$ | Highly dependent on adsorbed moisture films. |
   | Average Aspect Ratio (L/W) | $1.8:1$ | Dimensionless | Highly non-spherical due to cleavage planes. |
   | Isotopic Ratio ($\text{Oxygen}^{18}/\text{Oxygen}^{16}$) | $+15$ to $+30$ | per mil ($\text{\textperthousand}$) | Reflects high-temperature igneous origin for most airborne fract…
