यूक्रिट इसके अंग्रेजी अर्थ का उदाहरण

Several subgroups of both eucrites and diogenites have been found.

They are a regolith breccia consisting mostly of eucrite and diogenite fragments, although carbonaceous chondrules and impact melt can also occur.

An arbitrary divide between howardites and the polymict eucrites is a 9:1 ratio of eucrite to diogenite fragments.

Non-cumulate eucrites Are the most common variety and can be subdivided further:.

* Main series eucrites formed near the surface and are mostly, though not exclusively, regolith breccias lithified under the pressure of overlying newer deposits.

* Stannern trend eucrites are a rare variety.

* Nuevo Laredo trend eucrites are thought to come from deeper layers of 4 Vesta's crust, and are a transition group towards the cumulate eucrites.

Cumulate eucrites are rare types with oriented crystals, thought to have solidified in magma chambers deep within Vesta's crust.

Polymict eucrites are regolith breccias consisting of mostly eucrite fragments and less than one part in ten of diogenite, an arbitrary dividing line from the howardites, which are related in structure.

Diogenites are composed of igneous rocks of plutonic origin, having solidified slowly enough deep within Vesta's crust to form crystals which are larger than in the eucrites.
