The composition of a lava rock is a function of its mineral structure and chemical arrangement. One factor determining an igneous rock's composition is its classification as either a felsic or mafic rock. Felsic rocks are dominated by silicon and aluminum minerals, whereas mafic rocks are dominate...
Minerals are naturally occurring, inorganic solids with a specific chemical composition, while rocks are aggregates of one or more minerals.

Rocks and minerals hold precious clues about how Earth formed and evolved over billions of years — but what is the difference between the two? In essence, rocks are aggregates of two or more minerals. Minerals, meanwhile, are solids that, with a few exceptions such as diamonds, lack car...
Which metamorphic rocks are likely to contain garnet? What type of rocks recrystallize to form metamorphic rocks? What is the hardness of sandstone? What type of rock is gneiss? What is the mineral composition of quartzite? What are some common structures that sedimentary rocks can have?
In 1971, NASA developedLunarand demonstrated it at a space convention. The Lunar Sciences Natural Language Information System answered convention attendees' questions about the composition of the rocks returned from the Apollo moon missions. Translating languages was a difficult task before this, as the...
Depending on the composition of the rocks being metamorphosed, there are two major types of metamorphic texture. Foliated metamorphic rocks are arranged in sheets or planes, meaning that the composition of the rocks is relatively uniform and disperses fairly evenly due to pressure. Undifferentiated ...
