Regulated minerals known as asbestos are chrysotile, amosite, crocidolite, tremolite, actinolite & anthophyllite.

Explanation:
Asbestos regulation hinges on asbestiform fibers, not just the mineral species. The six minerals listed can occur as asbestos fibers, but regulation applies to asbestiform varieties specifically. Not every occurrence of tremolite, actinolite, anthophyllite, or the other minerals is in an asbestiform form, so claiming that all of them are regulated as asbestos is too broad. In practice, only the fibrous (asbestiform) forms of these minerals are treated as asbestos for regulatory purposes, meaning the statement isn’t universally true.
