Mangos shale‐associated alluvium

Abstract: Inquiry into the dissolution kinetics of naturally occurring geologic materials, rather than indiviual minerr. species, has been relatively neglected. This is especially true of surface processes, the realm of surface water hydrology and geomorphology. This paper focuses attention at a laboratory study of the rate of such complex reactions.Functions defining the dissolution rates of saline (0.1-20 per cent salt content) Mancos Shale-associated alluvium in distilled water follow varying patterns. Dissolution is… Show more

“…Underlying this is a looser granular sublayer of partially weathered shale shards grading gradually to dense, unweathered shale at a depth of 10 to 25 cm. When unweathered Mancos Shale is saturated with water, it decomposes within a few tens of hours into loose flaky chips with a modest net swelling (<25 per cent volume increase), yielding a yellowish liquor of dissolved salts (mostly sodium and calcium sulphates (Laronne, 1981(Laronne, , 1982). If these salts are not leached, further disintegration of the shale is inhibited.…”

“…The MS is the major source of solutes and suspended load in the Colorado River and numerous sulfate minerals have been reported (Whittig et al 1982;Larrone 1981) SO 4 ). The predominance of sodium sulfate species is particularly noteworthy.…”
