A Geologist's Ode to Olivine

The Geology Poem  - Ode to Olivine in Thin Section, a poem by Brenna Lorenz 
In basalt a lurid green Bespeaks the savage olivine; Mantle's child, born of fire, Restless in the open air, Little beads of anger bear The torture of desire. Silica upon its face It suffers, helpless, in disgrace, Its powers of reaction bound By solid's bond and cage, In agony confined to rage Unstable and unsound. Its birefringent power plays The sifted light to rare displays; The haunting, primal colors tell Of fire and fury's flag unfurled, Flag of fluid, nether world, Beneath the fragile shell.
