There are three major compositional groups of igneous rocks, mafic, felsic, and intermediate.
Mafic
The mafic igneous rocks are rich in magnesium and iron, making them a portmaneau of magnesium and ferric. They tend to be with dark coloration, with biotite and olivine being one of those rocks.
Felsic
The feslic igneous rocks are rich in elements that are forming the feldspar and quartz. Their coloration is lighter, and they come in numerous colors, with the granite and quartz being one of them.
Intermediate
The intermediate igneous rocks are in a way transitional rocks between the mafic and the felsic ones. They have a mixture of both mafic and felsic minerlas. Their coloration varies, and the andesite and dacite are some of them.
Expands would be the missing word
Explanation:
The two textures of the Evaporitic rocks are as follows -
1. Evaporitic rock textures show the same type of cyclicity which appears to be related to the chemical composition and salinity of the brine from which minerals are precipitating via the water evaporation and concentration of the brine. Permian evaporites of Germany show this type of texture.
2. To recognize evaporitic formation it requires recognition of halite pseudomorph, sequence composed some proportion of evaporite minerals, and also recognition of mud crack textures .
I live in Florida around the really really really hot parts so it's pretty different from Canada especially since there's blizzards and very cold climate around there, and Canada is farther north from Florida. I can't really think of some related things they both have in common.<span />
