Magma oldatokról van szó, nem vizes oldatokról (valószínűleg)

magmás = magmatic or igneous
üledékes = sedimentary rocks
átalakulási = metamorphic rocks
Különben a felsorolásod szerint és az előbbi állításommal ellentétben, lehet vizes oldatokból is.

Fazekas válasza jelen idejű, a kőzetek nem. Ez a pontos megfogalmazás. V.ö. Kázmér Gelógiai szótár

A kérdés az, hogy az "oldatból kivált" szavak módositják-e az értelmet. Szerintem nem, mert minden üledékes kőzet oldatból vált ki. Ezért van MM-nek igaza. Én csak szolgai módon leforditottam tautológiával a tautológiát.

Igazságod van. Figyelembe kellett volna vennem az egész megadott kontextust.
Szerintem ugyan ez a kategorizálás nem helyes, de neked azt kell leforditani, ami magyarul van. Használhatod az én (szószerinti) megoldásomat, vagy Creativity megoldását, amely MA szerint, ill. az általa idézett szövegrész szerint jónak látszik, bár én ezt a megoldást eddig nem ismertem.
Ezt támasztja alá ez a web-lap is:

"Detrital and Chemical Sedimentary Rock:
Sediments and the particulate mineral matter which compose sedimentary rocks are derived by the two different means of mechanical and chemical weathering. Sedimentary rocks may in turn be classified according to which of these two means resulted in their formation. Detrital sedimentary rock contains particles and sediment which were derived by mechanical means, while chemical sedimentary rock contains only substances which were derived by chemical weathering processes. The materials which compose detrital sedimentary rocks were ground down by mechanical processes such as wearing by wind, grinding by glaciers, and splitting due to cyclic freezing and thawing. These materials were also transported to the site of deposition by mechanical means such as wind, suspension in moving water, or travelling glaciers. These are compacted and cemented together; few chemical changes occur in the mineral material of which the rocks are composed. The constituent materials of chemical sedimentary rock, in contrast, were dissolved in water, transported to the deposition site in the form of aqueous solutions, and finally precipitated. Attack by rainwater and atmospheric carbon dioxide (CO2) may dissolve parent rock and allow it to be transported to the site of deposition. The precipitation of chemical sedimentary rocks may then be caused by either inorganic or organic agents. Inorganic processes include evaporation whereas organic processes occur when water-dwelling organisms extract calcite from their environment and in turn excrete a calcareous exoskeleton.
Sandstone provides an example of a familiar detrital sedimentary rock while limestone is perhaps the most well-known chemical sedimentary rock. Sandstone is so named because it is composed of sand-sized grains. Because the mineral quartz (SiO2) is quite stable and durable, it forms the most prominent constituent of most sandstones. Less stable or robust minerals often disintegrate during the mechanical weathering and collection processes which result in detrital sedimentary rocks.
Limestone is an example of a chemical sedimentary rock which may be formed through either inorganic or organic processes. Limestone stalactites (CaCO3) offer an example of inorganic precipitation. Such stalactites are formed as calcium-carbonate bearing water drips from an overhead projection in a cave. (The greek word stalaktos means 'dripping' or 'trickling'.) A minute quantity of calcium-carbonate is precipitated from each water droplet, slowly building up the pendulous stalactite formation. Many larger limestone deposits, on the other hand, are formed through organic precipitation. In particular this occurs when small organisms such as corals extract calcite from their ocean environment and secrete a calcareous extoskeleton. A colony of corals may over time achieve a massive, solid limestone reef.
Chemical sedimentary minerals which precipitate when evaporation removes the water in which they are dissolved are termed evaporites. These minerals include halite (NaCl), sylvite (KCl) and gypsum (CaSO4•2H2O). "
