is that saprolite is a chemically weathered rock while regolith is (geology) the layer of loose rock, dust, sand, and soil, resting on the bedrock, that constitutes the surface layer of most dry land on earth, the moon, and other large solid aggregated celestial objects .

Deeply weathered crystalline rock aquifer systems comprising unconsolidated saprolite and underlying fractured bedrock (saprock) underlie 40 % of subSaharan Africa. The vulnerability of this aquifer system to contamination, particularly in rapidly urbanizing areas, remains poorly understood.

The crystalline rocks in the area are weathered to saprolite, which extends from the surface of the ground to depths as great as 185 feet. The saprolite is 25 to 40 feet deep at most places. Weathering tends to bring about a convergence in the appearance of the various kinds of rock; the most thoroughly weathered rocks, despite differences in

Saprolites are residual soils formed on deeply weathered rocks and ordinarily retain the original structure of the parent rock. The units shown in Figure 1 include phosphate clays of central Florida and extensive saprolite exposures on the Piedmont Plateau, the Atlantic .

Porosity in saprolite. Seismic velocity in saprolite is lower than in unweathered granite for two reasons: increased porosity due to weathering, and the replacement of minerals such as feldspars with lowervelocity clays ( Olona et al., 2010).

Some huge landslides have occurred in deeply weathered rock, but most geologists and engineers do not appreciate the great depths that weathering can attain. Rocks can be weathered to depths of hundreds of metres, often in a very irregular manner. Fresh rock is converted to weathered rock called saprolite by isometric chemical alteration.

Apr 07, 2017· The dark reddish rock just below the break, known as saprolite, is highly erodible and may have contributed to the disaster. Note, also, the drain water flowing in from the sides of spillway, a sign of supersaturated soil conditions around the spillway.

Saprolite typically highly micaceous silt containing some sand and clay; contains none to many parting planes. Massive saprolite forms on massive rocks; parting planes develop on highly foliated bedrock.

hydraulic conductivity (K) of weathered igneous rocks decreases with depth or as the rock mass becomes less weathered. Generally studies of groundwater for determining slope stability treat the saprolite above the rockhead as an aquifer and the rockhead as an impermeable boundary.

Unexpectedly, saprolite and soil weathering intensities are inversely related, such that more weathered saprolites are overlain by weakly weathered soils. These data quantify exciting links between climate, weathering and erosion, and together suggest that climate controls chemical weathering via temperature and moisture control on chemical reaction rates.
