The present invention relates to an artificial stone tile comprising natural rock and a method for manufacturing the same. According to the present invention, the artificial stone tile may be manufactured by finely crushing natural rock, which is inexpensive to marble or granite, mixing the powder with an adhesive for increasing cohesion, heat resistance, durability and strength, forming the mixture into a tile shape under high pressure, and subjecting the formed tile to first calculation at high temperature, quenching at cold temperature, and second calcination at low temperature. The artificial stone tile may reproduce the same texture as natural stone, has better abrasion resistance and strength, is environmentally friendly without using synthetic resin, and may be supplied at low prices.
