Which minerals do you think have a higher value iron containing minerals or feldspar?
Iron-containing minerals typically have a higher value than feldspar due to their importance in steel production and other industrial applications. Iron is a vital component in many industries, leading to a higher demand and value for iron-containing minerals compared to feldspar, which is mainly used in glass and ceramics industries.
What are the two main feldspar groups?
The two main feldspar groups are potassium feldspar (orthoclase and microcline) and plagioclase feldspar (albite and anorthite). They are common rock-forming minerals in the Earth's crust and are essential components in many igneous and metamorphic rocks.
What are the two most common silicate in the Earth's crust?
Quartz and feldspars are the most common silicate minerals of the crust.
What property is the least useful in identifying minerals?
Color is often the least useful property in identifying minerals because many minerals can occur in a variety of colors due to impurities in their chemical composition. Instead, properties such as hardness, luster, and cleavage are more reliable for mineral identification.
What minerals found in crust?
The Earth's crust is primarily composed of minerals such as feldspar, quartz, mica, and pyroxene. Feldspar is the most abundant mineral group, making up about 60% of the crust, while quartz is prevalent in many types of rocks. Other important minerals include calcite, olivine, and amphibole, each contributing to the diverse geological formations found on the Earth's surface. These minerals play crucial roles in various geological processes and the formation of rocks.
One way to test a mineral is to break it and see how many directions of what it has?
cleavage....
What are two minerals with cleavage?
Halite and Calcite. Halite has what is known as cubiccleavage, where there is cleavage in three directions at 90 degree angles. Calcite has what is known as rhombohedral cleavage, where there is cleavage in three directions but at 120 and 60 degree angles.
Does a mineral have crystal form but no cleavage?
All minerals have a crystal form, but not all have cleavage.
One way to test a mineral is to break it and see how many directions of what it what?
...directions of cleavage...
Why isn't just determining if a mineral has cleavage enough to identify a mineral?
Because many minerals exhibit cleavage.
Tendency to break along smooth flat surfaces?
Many minerals have "cleavage" that causes them to split on flat cleavage planes. Such minerals include micas (muscovite, biotite. phlogopite), calcite, gypsum, and feldspars. Cleavage is the result of the minerals' crystal structure that has weaker chemical bonds aligned in planes.
Is feldspar a rock or mineral?
Feldspar is the name of a group of rock-forming minerals which make up as much as 60% of the Earth's crust. Feldspars crystallize from magma in both intrusive and extrusive rocks, and they can also occur as compact minerals, as veins, and are also present in many types of

Does sandstone have feldspar in it?
Sandstone will often contain feldspar, but some sandstones are composed entirely of quartz.
How many minerals are in granite?
4, quartz, feldspar, mica, and usually hornblende. hope this is helpful :)

What two minerals make up most of the sand in the world?
Quartz and feldspar are the two minerals that make up most of the sand in the world. Quartz is a common mineral found in many rocks, and feldspar is a group of minerals that are also abundant in the Earth's crust.
