The difference between quartzite and quartz is that in quartzite the grains have been what moving closer together.?
compacted
What are common uses of hornfels rock?
Hornfels may be used during construction projects or in the building of roadways. They may also be used as whetstones.
What is hornfels made of?
Hornfels is a metamorphic rock formed by the contact between mudstone / shale, or other clay-rich rock, and a hot igneous body, and represents a heat-altered equivalent of the original rock. This process is termed contact metamorphism. Because pressure is not a factor in the formation of hornfels, it lacks the foliation seen in many metamorphic rocks formed under high pressure and temperature regimes. Pre-existing bedding and structure of the parent rock is generally destroyed during the formation of hornfels.
Why are metamorphic rocks very hard and resistant to wear?
quartzite is made from quartz. in the case of metamorphic rocks, quartzite is made from regional metamorphism. in the process of regional metamorphism, pressure is applied making the rock hard and dense.
What is an example of a foliated metamorphic rock?
Foliated rocks have layers in them. We often refer to the layers as Banding.

What is the difference between metamorphic grade and metamorphic facies?
A metamorphic grade takes into account only the change in temperature while a metamorphic facies is more specific by showing the change in temperature in relation to the change in pressure and depth. There are three grades: low (250°C-400°C), intermediate (400°C-600°C) and high (above 600°C). Although there are many facies, the major ones are zeolite, hornfels, greenschist, amphibolite, blueschist, eclogite, and granulite. This allows for geologist to easily locate where a metamorphic rock was formed.

What is the difference between the two types of metamorphic rocks?
how is metamorphic rock different than intrusive rock
Is a quart a common metamorphic rock?
Quartz is a mineral found in many igneous, sedimentary, and metamorphic rocks. One metamorphic rock that is rich in quartz is quartzite. A quart is any of several archaic units of volume with values between 0.95 litre and 1.14 litre, the smallest and the largest of which are still used in the USA.
Is the difference between metamorphic rock igneous rock and sedimentary rock?
