Sentence examples for dissolution of secondary from inspiring English sources

The subsequent dissolution of secondary minerals is followed by the release of chemical species that include selenium and arsenic.

High concentrations of HCO3 and SO4 result from solute recycling and dissolution of secondary Ca-Mg carbonate/sulfate salts initially formed by near-surface evaporation in the summer and at depth by freeze-in of the active layer and cryoconcentration in the winter.

Direct mechanisms of arsenic mobilization include oxidative dissolution of primary arsenic minerals and reductive dissolution of secondary arsenic minerals [ 6].

The simulations predict a two-stage evolution of the cement porous matrix, after interaction with acid fluids from reservoir: (i) a first, "clogging" stage, characterized by a decrease in porosity due to calcite precipitation, and (ii) a second stage of porosity reopening, related to the disappearance of primary cement phases, and the re-dissolution of secondary minerals, such as zeolites.

In Hope Bay, they are subjected to very slow rates of dissolution, neoformation of secondary phosphatic minerals, and mineralogical transformation and leaching processes.

Transient releases at high pH are attributed to dissolution of amphoteric secondary phases such as ferrihydrite that are inferred from saturation calculations and solid analyses to form during the conditioning interval.

It is commonly known that the release of arsenic from As-bearing minerals may take place by two main processes: (i) oxidation of the primary arsenic minerals and (ii) reductive dissolution of the secondary minerals.

At depths greater than 20 cm below the natural ground surface, granular disintegration and corestone weathering are not evident, and dissolution and precipitation of secondary calcite is only observed within a few centimeters of joint planes.

Stage II is characterized by dissolution and infilling of secondary pore spaces (Fig. 8).

This correlation also signifies dissolution and leaching of secondary salts, with a significant correlation of HCO3− with Ca2+, Mg2+, PO42−, K+, and SO42−.

Longer sintering times lead to grain growth and to the dissolution of Sr-rich secondary phases and magnesium oxide, present in trace amounts at the grain boundaries, into the major perovskite phase.
