..., supporting the idea that these aluminum-silicate (AS) polymorphs crystallized at the same time. These data are consistent with the findings of Sharp (1995) , who reported no fractionation associated with polymorphism of the aluminum silicates. Quartz–aluminum-silicate fractionations from veins in textural...

...Alan Thomson; R. K. Stoessell ABSTRACT Porosity enhancement in sandstone reservoirs cannot be due to dissolution of aluminum silicates without implying aluminum mobility. However, aluminum has yet to be reported in reservoir fluids at greater than trace concentrations. Predicted aqueous aluminum...

...W. D. Keller ABSTRACT Some observations have shown that certain aluminum silicate rocks weather directly to bauxite, but other observations indicate that the same rock types weather elsewhere to kaolinite which may then undergo weathering to bauxite (bauxite refers herein to a rock composed...

..., and especially of the artificial zeolite known as permu-tite, is contrary to the condition in all anhydrous silicates, it seems worth while to test the matter somewhat carefully, particularly since it has been found that a different explanation can be applied to thomsonite. 1 Copyright © 1925...
