Journal Article
Published: 29 October 2012
Geological Magazine (2013) 150 (3): 385–395.
...ALICJA M. LACINSKA; MICHAEL T. STYLES Abstract Mineralogical studies of a silicified serpentinite from the United Arab Emirates throw light on the formative processes. The silicified serpentinite is a residuum of a palaeo-weathering surface that probably developed in a temperate climate...

...M. Cornelius; I.D.M. Robertson; A.J. Cornelius; P.A. Morris Abstract Multi-element analysis of ferruginous nodules and pisoliths from lateritic residuum, derived lag and ferruginous gravel, selected from locally derived colluvium (laterite) sampled at an approximate 9 km interval (triangular grid...

... thick. The regolith consists of 50 m-thick saprolite, which is clay-rich in the top 10 m, plasmic and mottled clays, lateritic residuum (duricrusts and gravels) and pisolitic soils; the surficial horizons contain pedogenic carbonates. Elements occurring with primary Au mineralization are S, Ag, W...

... of various ages. Four general types are recognized: ferruginous duricrust and gravel, ferruginous mottles, ferruginous saprolite and iron segregations. Ferruginous duricrusts include lateritic residuum and ferricrete. Lateritic residuum has evolved by partial collapse of mottled or ferruginous regolith...

... horizon. Profile 4 was collected on the edge of calcrete-poor lateritic residuum, which explains the low Ca and Mg contents reported for the corresponding augered samples. Gold enrichment in calcareous soil downslope from the main mineralized zone ( Fig. 4a, c, d) to the east of Profile 1 is probably...

... evolution and their significance to exploration. The residual materials (lateritic residuum and ferruginous saprolite) have Au, W and Cu anomalies in the vicinity of the deposit. Elements associated with the Au mineralization in the lateritic residuum of the Laterite Pit are Ag, Ba, Ce, W, Mo, As, Sb and Cu...

DOI: 10.1130/SPE271-p29
... Soil-gas radon and ground radioactivity surveys across a portion of the Great Valley of West Virginia indicate that residuum and soils formed above some carbonate rocks have sufficient levels of radon gas to cause high indoor radon values. Data indicate no correlation of soil-gas radon...

... movement location. This long-duration rainfall at moderate intensities triggered more than 1,000 slope movements in a 1,040-km 2 study area. Most were shallow slips and slip-flows in thin colluvium and residuum on shale slopes. Locations of these failures were sensitive to land cover and slope aspect...

... coast of Puerto Rico. Locally, 24-hr rainfall exceeded 560 mm, 4-day rainfall exceeded 750 mm, and intensities reached 70 mm/hr. Most of the flows occurred in an area where Tertiary limestone and detrital sediments form 20° to 40° slopes covered by less than 2 m of colluvium or residuum. Many areas...

..., coquimbite, halotrichite, gypsum, and possibly other sulfates. Basaluminite, a hydrous aluminum sulfate previously reported only from England and France, was found in geodal cavities and thin seams in the residuum. The clayey zone has been previously interpreted as an ancient soil formed on the limestone...
