However, there is still little agreement on just what the results mean for anorthosite genesis; see the'Origins'section below.

In summary, though liquid-state processes clearly operate in some anorthosite plutons, the plutons are probably not derived from anorthositic magmas.

The glaciers, and later meltwater, wore away less resistant rock, leaving behind hills and ridges of the harder diabase and anorthosite.

Failing to make sandpaper with the anorthosite, the founders decided to import minerals like Spanish garnet, after which sale of sandpapers grew.
35.
This anorthosite rock is composed almost exclusively of the calcium-rich feldspar mineral anorthite, and is believed to be representative of the highland crust.

Between these zones are outcrops of Silurian Fox Back Ridge diorite and granodiorite, as well as the Red River Anorthosite Suite of Middle Proterozoic age.

Anorthosite on Earth can be divided into two types : Proterozoic anorthosite ( also known as massif or massif-type anorthosite ) and Archean anorthosite.
