How about apatite, apophyllite, axinite, chlorite, hypersthene, scapolite, serpentine, tantalite, and wolframite? |
|
Little-weathered grains of hypersthene and rare clasts of limestone persist throughout the profile, as evidence for limited chemical weathering. |
|
The Johnstown meteorite is classified as a calcium-poor diogenite, being composed mainly of hypersthene, with minor amounts of plagioclase and olivine. |
|
The hypersthene diabase grades upward into diabase with variable texture and grain size, and is locally aplitic, granophyric or pegmatitic. |
|
Quartz diabase grades upward into hypersthene diabase, which forms up to two-thirds of the sill thickness. |
