Definition
Hawaiite is volcanic rock that resembles basalt. It is an olivine basalt with intermediate composition between alkali olivine and mugearite
Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar

Formation
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

More about Hawaiite and Arkose
Here you can know more about Hawaiite and Arkose. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hawaiite and Arkose consists of mineral content and compound content. The mineral content of Hawaiite includes Olivine, Plagioclase, Pyroxene and mineral content of Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Hawaiite vs Arkose, the texture, color and appearance plays an important role in determining the type of rock. Hawaiite is available in black, brown, light to dark grey colors whereas, Arkose is available in reddish brown colors. Appearance of Hawaiite is Dull and Soft and that of Arkose is Rough and Dull.
