Asbestiform – Definition & Meaning

Asbestiform is a term that is often used in geological and mineralogical contexts. It refers to the fibrous or needle-like shape of certain minerals, which can resemble the dangerous mineral asbestos. Asbestos is a naturally occurring mineral that was widely used in construction and manufacturing until its health risks were discovered. Asbestiform minerals, which share some of the same physical properties as asbestos, can also pose health risks if they are inhaled or ingested. In this article, we will explore the definition and meaning of asbestiform in greater depth.


Asbestiform is an adjective that describes the fibrous or needle-like shape of certain minerals. These minerals are characterized by long, thin crystals that can be easily separated into fibers. Asbestiform minerals can include a variety of substances, such as amphiboles, serpentines, and other silicates.


The word asbestiform comes from the Greek word “asbestos,” which means “unquenchable” or “inextinguishable.” This refers to the fact that asbestos fibers are resistant to heat and fire. The suffix “-form” is added to indicate the shape of the mineral.

Meaning in different dictionaries

Asbestiform is a technical term that is not commonly found in general dictionaries. However, it is defined in specialized geological and mineralogical references, such as the Glossary of Geology and the Dictionary of Mining, Mineral, and Related Terms. These sources define asbestiform as “having a fibrous or needle-like habit.”


Asbestiform minerals are often associated with geological formations that contain asbestos. These minerals can also be found in other types of rocks and soils, and may be present in building materials or other products. Asbestiform minerals can pose health risks if they are disturbed, as they can release fibers into the air that can be inhaled or ingested.


There are several synonyms for asbestiform, including fibrous, acicular, and needle-like. These terms are used to describe the shape of minerals that have a similar appearance to asbestos fibers.


There are no direct antonyms for asbestiform, as it is a term that describes a specific shape of mineral. However, minerals that do not have a fibrous or needle-like shape could be described as blocky, granular, or massive.

The same root words

The root word “asbestos” is also found in other terms related to the mineral, such as “asbestosis” (a lung disease caused by inhaling asbestos fibers) and “asbestos-containing materials” (building materials that contain asbestos).

Example Sentences
