Understanding cratonic flood basalts

The origin of continental flood basalts has been debated for decades. These eruptions often produce millions of cubic kilometers of basalt on timescales of only a million years. Although flood basalts are found in a variety of settings, no locale is more puzzling than cratonic areas such as southern Africa or the Siberian craton, where strong, thick lithosphere is breached by these large basalt...

closed system grossly distorted sound calibration below 1 khz, whereas at frequencies higher than 6 khz calibration for the open loudspeaker was affected. This difficulty could be avoided by placing the loudspeaker close to the bird's ear (12 cm). 2. R. L. Boord and G. L. Rasmussen, J. Comp. Neurol. 120, 463 (1963). 3. For this reason, all data on single-unit thresholds and frequency range in t...
