Dust resuspension without saltation.
Wind resuspension (or entrainment) provides a source of dust and contaminants for the atmosphere. Conventional wind erosion models parameterize dust resuspension flux with a threshold velocity or with a horizontal abrasion flux; in the absence of abrasion the models assume dust flux is transient only. Our experiments with an uncrusted, fine material at relative humidities exceeding 40% show a l...
متن کاملInfluence of Gravity on the Geometry of Martian Normal Faults
Introduction: Extensional fault scarps on Mars bear a striking resemblance to fault scarps on Earth, including geometric features such as horsts, grabens, relay ramps and breached relay ramps, en echelon arrangement of faults and grabens, and scaling characteristics [1], [2], [3]. Other surface features associated with extensional faulting on Mars are lines (" chains ") of circular topo-graphic...

15 صفحه اولSaltation impact as a means for raising dust on Mars
Experiments were conducted under atmospheric pressures appropriate for Earth and Mars to determine the e,ciency of sand in saltation as a means for raising dust into the atmosphere under wind speeds which would otherwise be too low for dust entrainment. Experiments involving intimate mixtures of sand and dust (1:1 ratio by mass) showed that after an initial .urry of activity of a few seconds du...
