Definition
Websterite is ultramafic and ultrabasic rock that consists of roughly equal proportions of orthopyroxene and clinopyroxene. It is a special type of pyroxenite.
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone

Archaeological Significance
Formation
Websterite can be formed as cumulates in ultramafic intrusions by accumulation of pyroxene crystals at the base of the lava chamber.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

More about Websterite and Diamictite
Here you can know more about Websterite and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Websterite and Diamictite consists of mineral content and compound content. The mineral content of Websterite includes Amphibole, Augite, Bronzite, Chromite, Diopside, Enstatite, Garnet, Hornblende, Hypersthene, Magnetite, Pyroxene and mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Websterite vs Diamictite, the texture, color and appearance plays an important role in determining the type of rock. Websterite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey colors whereas, Diamictite is available in brown, buff colors. Appearance of Websterite is Layered, Banded, Veined and Shiny and that of Diamictite is Banded. Properties of rock is another aspect for Websterite vs Diamictite. The hardness of Websterite is 7 and that of Diamictite is 2-3. The types of Websterite are Ultramafic rock whereas types of Diamictite are Bedded Diamictite and Laminated Diamictite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Websterite is white, greenish white or grey while that of Diamictite is light to dark brown.
