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.
  
Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

More about Jasperoid and Blueschist
Here you can know more about Jasperoid and Blueschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jasperoid and Blueschist consists of mineral content and compound content. The mineral content of Jasperoid includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Blueschist includes Albite, Chlorite, Epidote, Garnet, Glaucophane, Lawsonite, Muscovite or Illite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Jasperoid vs Blueschist, 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, Blueschist is available in blue, bluish - grey, purple, shades of blue colors. Appearance of Jasperoid is Glassy or Pearly and that of Blueschist is Dull and Banded. Properties of rock is another aspect for Jasperoid vs Blueschist. Hardness of Jasperoid and Blueschist is 3.5-4. The types of Jasperoid are Not Available whereas types of Blueschist are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface.
