Internal feedbacks between erosion and weathering also play an integral role in regulating the landscapes response. Our understanding of these internal and external feedbacks is limited to a handful of field-based studies, only a few of which have explicitly examined saprolite weathering.

Saprolite, regolity and soil | SpringerLink
Saprolite, as defined in the Glossary of Geology (Bates and Jackson, 1980), is a soft, earthy, typically clay-rich, thoroughly decomposed rock, formed in place by chemical weathering of igneous, sedimentary, and metamorphic rocks. Because saprolites are characterized by preservation of structures that were present in the unweathered rock, it is ...

Spheroidal weathering - Wikipedia
Spheroidal weathering is a form of chemical weathering that affects jointed bedrock and results in the formation of concentric or spherical layers of highly decayed rock within weathered bedrock that is known as saprolite. When saprolite is exposed by physical erosion, these concentric layers peel (spall) off as concentric shells much like the layers of a peeled onion.
-
Geochemistry and mineralogy of a saprolite developed on ...
Rocks in the uppermost saprolite have been converted to an assemblage of Al-smectite + hematite (+kaolinite). These results suggest that the presence of nontronite in weathered samples may indicate weathering under conditions of limited permeability; however, it does not necessarily indicate weathering in a chemically closed system.

Modeling unsaturated flow and transport in the saprolite ...
In humid climates, in situ weathering of bedrock can form saprolite. Saprolite usually has high matrix porosity (and variable permeability) that is a reservoir for solute storage and can have relict fractures that transport solute rapidly.
-
Regolith and saprolite | SpringerLink
The definition of saprolite implies that chemical components have been removed by groundwater during the weathering process (Clarke, 1910), but that interstitial grain relations are undisturbed. Saprolite is often equivalent to the C-horizon of pedology.

Geochemistry of Saprolite from Redwood Falls, MN
A saprolite dominated by quartz, kaolinite, and sericite was formed from chemical weathering of Morton Gneiss in the Minnesota River Valley. Since sericite is a secondary mineral not found in the parent rock, its geochemistry is a useful tool for deciphering the weathering history of the saprolite. Electron microprobe analysis shows

Weathering Profile - an overview | ScienceDirect Topics
Most weathering profiles include a basal interval of compact altered rock, termed ‘saprock’ (Zauyah, 1986; Tonui et al., 2003), which is a term adopted from Meunier et al. (1983), and mostly corresponds to the so-called lower saprolite.

saprolite weathering is of great importance. Through the study of saprolite weathering in HongKong, we find that many kinds of original minerals including albite which is sensitive to weathering still remain in saprolite, but in different kinds of forms. This can be used to identify the weathering degree of saprolite.
