Formation
Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.
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 Jasperoid and Arkose
Here you can know more about Jasperoid and Arkose. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jasperoid and Arkose consists of mineral content and compound content. The mineral content of Jasperoid includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Jasperoid vs Arkose, the texture, color and appearance plays an important role in determining the type of rock. Jasperoid is available in black, brown, colourless, green, grey, pink, white colors whereas, Arkose is available in reddish brown colors. Appearance of Jasperoid is Glassy or Pearly and that of Arkose is Rough and Dull. Properties of rock is another aspect for Jasperoid vs Arkose. The hardness of Jasperoid is 3.5-4 and that of Arkose is 6-7. The types of Jasperoid are Not Available whereas types of Arkose are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Jasperoid and Arkose is white. The specific heat capacity of Jasperoid is 0.92 kJ/Kg K and that of Arkose is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Jasperoid is heat resistant, pressure resistant, wear resistant whereas Arkose is heat resistant, impact resistant, pressure resistant.
