Pronunciation: [sˈɪməlˌa͡ɪt] (IPA) 
Cimolite is a mineral that is commonly found in sedimentary rocks. The correct spelling of this word follows the rules of English orthography, where the "c" is pronounced as /s/ and the "i" has a short vowel sound /ɪ/. The "m" is pronounced as /m/ and the "o" has a long vowel sound /oʊ/. The final "l" is pronounced as /l/, and the final syllable "ite" is pronounced as /aɪt/. The IPA transcription of the word Cimolite is /ˈsɪməlaɪt/.
Cimolite is a fine-grained sedimentary rock that belongs to the group of clay minerals known as smectite. It is typically characterized by its high content of montmorillonite, a particularly expansive clay mineral. Cimolite primarily forms in marine environments, particularly in shallow marine or lacustrine (lake) settings, where it accumulates in layers over time.
The mineral composition of cimolite consists mainly of aluminum silicates with variable amounts of other elements like calcium, magnesium, and sodium. Its fine-grained texture is a result of the clay minerals being broken down and reformed over geological time. Cimolite often contains organic matter, micropores, and minute crystals of other minerals.
Due to its unique properties, cimolite has several uses and applications. It is commonly employed as a drilling mud additive in the oil and gas industry, where it helps control the viscosity and stability of drilling fluids. Cimolite is also utilized in the production of ceramics, where it acts as a binder and enhances the plasticity of the clay.
In terms of appearance, cimolite typically exhibits colors ranging from white or light grey to pale yellow or greenish hues. Its softness and low hardness make it easily malleable when moist, but it may harden upon drying. Cimolite has a characteristic earthy odor when wet due to the presence of organic matter.
A pure white or greyish-white variety of clay from the island of Cimola, in the Grecian Archipelago, used as a fuller's earth.

The word "Cimolite" comes from the Greek word "kímōlon", meaning "mud" or "ooze". The suffix "-ite" is commonly used in geology to denote a specific type of mineral or rock. Therefore, "Cimolite" refers to a type of clay or sedimentary rock that is characterized by its high clay content and earthy, soft consistency.
