Anorthitic is a term that is commonly used in the field of geology. It refers to a type of mineral that is found in igneous rocks, specifically in the plagioclase feldspar group. This mineral is important in the study of rocks and their formation, as it can provide valuable information about the conditions under which the rock was formed. In this article, we will explore the definition and meaning of anorthitic, as well as its origin, associations, synonyms, and antonyms.
Definitions
Anorthitic is defined as a mineral that belongs to the plagioclase feldspar group. It is a calcium-rich mineral that is typically white or gray in color, and has a glassy or pearly luster. Anorthitic is also used to describe rocks that contain this mineral.
Origin
The word anorthitic comes from the Greek word “anorthos,” which means “oblique.” This is a reference to the oblique cleavage of the plagioclase feldspar group, to which anorthitic belongs. The term was first used in the mid-19th century by geologists who were studying the mineral and its properties.
Meaning in different dictionaries
Anorthitic is not a commonly used word, and as such, it may not be found in many dictionaries. However, it can be found in specialized geological dictionaries, where it is defined as a mineral that is part of the plagioclase feldspar group.
Associations
Anorthitic is commonly found in igneous rocks such as basalt, gabbro, and anorthosite. It is also found in some metamorphic rocks, such as gneiss and schist. Anorthitic is associated with other minerals such as olivine, pyroxene, and quartz.
Synonyms
Some synonyms for anorthitic include plagioclase, albite, and labradorite. These terms are also used to describe minerals that belong to the plagioclase feldspar group.
Antonyms
There are no direct antonyms for anorthitic, as it is a specific type of mineral. However, it can be contrasted with other minerals that are found in igneous and metamorphic rocks, such as mica and calcite.
The same root words
Anorthitic is derived from the Greek word “anorthos,” which means “oblique.” This root word is also found in other geological terms, such as anorthosite, which is a type of igneous rock that contains anorthitic feldspar.
Example Sentences
- The anorthitic mineral was identified in the basalt rock sample.
- The anorthitic feldspar in the gneiss rock indicated that it had undergone metamorphism.
- The labradorite and albite minerals are also part of the plagioclase feldspar group, along with anorthitic.
