Authigenesis is a term that is commonly used in geology and refers to the formation of minerals or rocks in place, as opposed to being transported from somewhere else. This process occurs when minerals precipitate from water or other fluids within the sediment or rock, creating new minerals that were not present in the original material. This article will explore the definition, origin, meaning, associations, synonyms, antonyms, and example sentences of authigenesis.
Definitions
The term authigenesis is derived from the Greek words “auto,” meaning “self,” and “genesis,” meaning “origin.” In geology, authigenesis refers to the formation of minerals or rocks in place, as opposed to being transported from somewhere else. This process occurs when minerals precipitate from water or other fluids within the sediment or rock, creating new minerals that were not present in the original material.
Origin
The origin of authigenesis can be traced back to the early days of geology when scientists were trying to understand the formation of rocks and minerals. The term was first used in the mid-19th century by French geologist Alexandre Brongniart to describe the formation of minerals in situ.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, authigenesis is defined as “the formation of minerals or rocks in place by precipitation from solution or deposition from suspension within the sediment or rock mass in which they occur.”
The Oxford English Dictionary defines authigenesis as “the formation of a mineral or rock in situ, as opposed to being transported from elsewhere.”
Associations
Authigenesis is commonly associated with sedimentary rocks, which are formed by the accumulation and cementation of sediment. The process of authigenesis can also occur in metamorphic rocks, where minerals are formed due to the heat and pressure of the surrounding environment.
Synonyms
Synonyms of authigenesis include in situ mineralization, diagenesis, and cementation.
Antonyms
Antonyms of authigenesis include detrital sedimentation, which refers to the transport and deposition of sediment from another location.
The same root words
The same root words as authigenesis include auto, which means self, and genesis, which means origin.
