U-Th Series Nuclides in Aquatic Systems
Radiotracer approaches feature prominently in attempts to refine models of
sediment mixing (Martin and Sayles, 2003). The tendency for uranium to
precipitate in marine sediments under reducing conditions has led to the use of
authigenic U ...

Potassium feldspar occurs in the equation for boron in western wheatgrass and
big sagebrush. Boron is thought to reside in authigenic potassium feldspars in
the Green River and Uinta Formations (Sheppard and Gude, 1973). The boron ...

U.S. Geological Survey Professional Paper
Authigenic phases observed in fine-grained sandstones are predominantly
carbonate minerals (fig. 6 ). Authigenic carbonate cements also are most
common in the coarser grained sandstones, particularly those that have high
concentrations ...

In some cases overgrowths were bigger than the initial grain or surrounded
several grains (Fig. 4, 12). Relatively thick overgrowths occurred in sandstones.
Sometimes, especially in dolomite-cemented sand- and siltstones, the authigenic
rim ...
Dibble & Tiller (1981) proposed a kinetic model for the formation of authigenic
silicates in tuffaceous rocks. The model incorporates the idea that rates of glass
dissolution proceed at much greater rates than stable authigenic minerals, such
as ...

Introduction Authigenic1 silicates are widespread in deep-sea sediments. The
most commonly observed and suggested diagenetic2 reactions responsible for
the formation of authigenic silicates in the deep-sea environment are
summarized in ...
