What else can I help you with?
What kind of igneous rocks that are composed of an amphibole and intermediate plagioclase?
Granite and diorite contain both.
Which rocks contain silicon?
Silicon is commonly found in minerals such as quartz, feldspar, and mica, which are abundant in many types of rocks like granite, sandstone, and shale. These rocks typically contain varying amounts of silicon in their mineral composition.
How can you tell rocks apart from minerals?
Minerals contain one or many types of minerals (copper, gold, zinc) Rocks contain different types of minerals (Granite- Feldspar, Quartz, Mica, Hornblende)
How many types of granite rocks?
hoe many types of granite rocks are there
What types of rocks contain crystals?
Igneous rocks, such as granite and basalt, often contain crystals due to their formation from molten magma cooling and solidifying. Metamorphic rocks, like marble and quartzite, can also have crystals as a result of intense heat and pressure altering existing rocks.
How are gneiss rocks different that granite rocks?
Gneiss rocks are products of metamorphism while granite rocks are derived from igneous activity.
Why are granite igneos rocks lighter in color than basaltic rocks?
Granite igneous rocks are lighter in color than basaltic rocks primarily due to their mineral composition. Granite is rich in light-colored minerals such as quartz and feldspar, which contribute to its lighter hues. In contrast, basaltic rocks contain a higher proportion of dark-colored minerals like pyroxene and olivine, resulting in their darker appearance. This difference in mineralogy reflects the varying magma compositions from which these rocks are formed.
Does granite contain gold?
Yes, granite can contain small amounts of gold
Is it possible for granite to have fossils or shells in it?
Yes, it is possible for granite to contain fossils or shells. This occurs when sedimentary rocks containing fossils or shells are metamorphosed and transformed into granite over time. The original fossils or shells may be preserved within the granite, although they may be altered or distorted due to the intense heat and pressure of the metamorphic process.
What group of rocks would granite be?
Granite is an igneous rock.
Is granite an ore?
No, granite is not an ore. Granite is an igneous rock that forms from the cooling of magma and is commonly used in construction and sculpture due to its durability and aesthetic appeal. Ores are minerals or rocks that contain valuable materials that can be extracted economically, such as iron ore or gold ore.
What do granite and gabbro have in common?
Granite and gabbro are both types of igneous rocks that solidify from molten material beneath the Earth's surface. They both contain large mineral crystals, with granite being a coarse-grained rock and gabbro being a fine-grained rock. Additionally, both rocks are commonly used in construction and as decorative stone.
