of quartz in the fluids results from drastic temperature changes in the range 450 350 [degree]C, and in most cases the K or Na metasomatism is controlled by the subsequent disequilibrium between fluids and host rocks (Cathelineau, 1986).
In general, oxygen exhibited undersaturation
conditions, most likely because of the high organic load.
Dissolution of carbonate rocks occur as a result of undersaturation
of pore fluid that lead to dissolution of metastable carbonate grains and cement (aragonite/high- magnesium calcite; FlA1/4gel 2004).
Downing, 2011: Carbon dioxide concentrations in eutrophic lakes: Undersaturation
implies atmospheric uptake.
2008) reported that coccolithophores are common in the Black Sea, where surface waters are saturated with carbonate year-round, but absent from the Baltic Sea, which has seasonal carbonate undersaturation
The approximate steady-state dissolution of the synthetic goethite and Kk samples in this study showed undersaturation
with respect to goethite and hematite, with [[DELTA].
It may act as a chelator capable of binding the minerals (calcium) of enamel or dentine, thus increasing the degree of undersaturation
and favouring demineralisation.
can build up to dangerous levels and deprive these animals of the basic building blocks they need to maintain their shells.
This "Report to an Academy" consists of reflections on how the restlessly cynical university has become the last self-appointed bastion of the humanities in an epoch of the undersaturation
of the age with history.
RS is the ratio of calcite activity product (Ka) to calcite solubility product (Ksp), SI value of less than 1 indicates undersaturation
, SI of 1 indicates saturation, and SI of more than 1 indicates supersaturation.
Simultaneously with the decrease in the influx of carbonate products by surface and subsurface waters as a result of considerable lixiviation of till layers, carbonate balance in lake water was disturbed: oversaturation was replaced by undersaturation
and the stage of Si[O.
In the Drain, the alunite disequilibrium coefficient indicated undersaturation
early in the 1997 wet season followed by supersaturation and then strong supersaturation with [D.
