Actinolite

In accompanying notes, a geologist identified as W.J. Hunter boasted of a rock formation from the Miocene Epoch that gleamed with boulders of "tourmaline-actinolite-quartz plutonites." ❋ Unknown (2009)

Greenstone, diorite, and actinolite are found, though not so abundantly as those above mentioned. ❋ Unknown (2003)

In particular, the minerals concerned are: chrysotile, amosite, crocidolite, anthophyllite, tremolite und actinolite, which are categorized on the basis of their chemical composition and fibrous structure as serpentine Asbestos ❋ Unknown (1996)

The general character of the rock here is sienitic; but, besides this peculiar quality of feldspar, the hornblende appears as actinolite, (ray-stone,) so called from the form of its crystallization; while the quartz element is faintly present, or appears in separate masses. ❋ Various (N/A)

_Chalcedony_ too (which when banded furnishes us our _agates_, and when reddish our _carnelian_) is a variety of quartz, and _prase_ is only quartz colored green by fibers of actinolite within it. ❋ Frank Bertram Wade (N/A)

These include a dangerous fibrous asbestos as well as the harmless monoclinic amphibole, actinolite: two minerals with the same composition but very different effects on human physiology. ❋ Mike Rivero (2010)

The six types of asbestos are chrysotile, crocidolite, amosite, anthophyllite asbestos, tremolite asbestos, and actinolite asbestos. ❋ Unknown (2009)

Libby vermiculite is contaminated with an especially toxic form of naturally-occurring asbestos called tremolite-actinolite asbestiform mineral fibers. ❋ Unknown (2009)

South - west of this, five miles above Catar6 to the west of the road, and northwest of Mount Basimo, he obtained a dark-colored actinolite slate. ❋ Unknown (1771)

The types amosite, anthopyllite, tremolite and actinolite are quantitatively (together 50 000 ❋ Unknown (1996)
