| The inhalation of amphibole asbestos is now widely recognized as being highly dangerous to human health. |
| The presence of several amphibole minerals, such as tremolite, actinolite, anthophyllite, was confirmed. |
| In practice many basalts also contain easily visible crystals of feldspar, pyroxene, olivine, or amphibole. |
| This is consistent with the fact that olivine is typically entrapped in pyroxene and amphibole crystals. |
| In keeping with their amphibole content, almost all the samples are metaluminous to slightly peraluminous. |
| The structure of an amphibole is a double chain of silicate tetrahedral which makes it very strong and durable. |
