From the geology course I took in 1975: Minerals are naturally occurring crystals of compound. Snow is a mineral, but volcanic glass is not. Rocks are amalgams of minerals and non-minerals.
In corpus linguistics, a collocation is a sequence of words or terms that co-occur more often than would be expected by chance. In phraseology, collocation is a sub-type of phraseme. An example of a phraseological collocation, as propounded by Michael Halliday, is the expression strong tea.
Collocation and colocation are often spelled incorrectly, regardless of which term people are attempting to use: 1  Collocation is moving or or placing things together, sometimes implying a proper order. 2  Colocation (sometimes co-location) is an Internet and telecommunications specific term. Colocation refers to the provision of space for a customer's telecommunications equipment on the service provider's premises.
