What else can I help you with?
What classification of metamorphic rocks would include whether they are?
Foliated or non-foliated. Foliated metamorphic rocks have a layered or banded appearance due to the alignment of minerals, while non-foliated rocks do not exhibit this feature.
What are the major classification of rocks?
igneous, metamorphic, and sedimentary
What classification or kind of rocks results when rocks eroded from higher elevations accumulate at lower elevations?
asial sedimentary igneous metamorphic
Are metamorphic rocks only formed by igneous rocks?
No. Metamorphic rocks can also from front sedimentary rocks and from other metamorphic rocks.
A classification scheme that grouped plutonic and metamorphic rocks together and sedimentary and volcanic rocks together would be based on what?
This classification scheme would likely be based on the genesis or origin of the rocks, as plutonic and metamorphic rocks are both associated with processes occurring beneath the Earth's surface (igneous intrusion and metamorphism), while sedimentary and volcanic rocks form at or near the Earth's surface through sedimentation and volcanic activity, respectively.
Changed-over rocks are called?
Metamorphic Rocks
Is metamorphic rocks made up of sedimentary rock igneous rock or other metamorphic rocks?
Metamorphic rocks
Are unakite rocks Metamorphic rocks or igneous rocks?
It is a type of Metamorphic rock
What does rock classification mean?
Rock classification is the process of categorizing rocks based on their physical, chemical, and mineralogical properties. This helps geologists understand the origins and characteristics of different rocks, such as sedimentary, igneous, and metamorphic rocks. Classifying rocks also aids in studying the Earth's history and geological processes.
What are three types of rocks?
igneous, sedimentary, metamorphic
Can metamorphic rocks form form igneous but not from sedimentary rocks?
Metamorphic rocks can form from both igneous and sedimentary rocks through the process of heat and pressure, but they are more commonly associated with forming from existing metamorphic or sedimentary rocks. Igneous rocks can indirectly contribute to the formation of metamorphic rocks by heating up and altering surrounding rocks, leading to the formation of new metamorphic rocks.
How many metamorphic rock are there?
Metamorphic rocks have been modified by heat, pressure and chemical process usually while buried deep below Earth's surface. Exposure to these extreme conditions has altered the mineralogy, texture and chemical composition of the rocks. There are two basic types of metamorphic rocks: 1) foliated metamorphic rocks such as gneiss, phyllite, schist and slate which have a layered or banded appearance that is produced by exposure to heat and directed pressure; and, 2) non-foliated metamorphic rocks such as marble and quartzite which do not have a layered or banded appearance. Pictures and brief descriptions of some common types of metamorphic rocks are provided below.
