To study the effect of stress-activated positive hole (p-hole) charge carriers on the infrared (IR) emission from rocks, we subjected a portion ( ∼10 vol.%) of a large (30×60×7.5 cm3) block of anorthosite, a nearly monomineralic (Ca-rich feldspar) igneous rock, to uniaxial deviatory stress up to failure. We measured the IR emission from a flat surface≈40 cm from the stressed rock volume over the 800–1300 cm−1 (7.7–12.5μm) range. Instantly, upon loading, the emission spectrum and intensity… CONTINUE READING
