Sandstone is one of sedimentary rocks which have a large distribution in whole a part of the earth. Between 20% until 25% is the rate of sandstone distribution in each earth layer. From the heights until the deep ocean, we still found the sandstone layers in each portion. Sedimentary rock is rock that formed by diagenesis of other rock that has been sedimented. The sandstone composed of sediment materials from others process such as weathering and erosion of any other rocks. The reworking process is being continuously to provide the sediment materials which transported until each sedimentary basin. The rough materials will proceed to be smaller and smoother materials depend on how far it transported. The sandstone is meaning sedimentary rocks which have the size rate between 1/16 until 2 mm. The size that is called sand can be very rough until the smallest one is very fine. Sandstone have the moderate grain size, not too rough like pebble, granule, cobble or boulder but not too fine like silt or clay. So, there is easier to form the sand grain size, to transport them and to make them deposited. That’s why we can found the sand deposit or sandstone almost in everywhere.

We can intepreted the clastic by its texture. Texture is the appearance related to the size and shape of the grain as well as its composition.<ref name=Pettijohn1975>Pettijohn, F.

Dokontrol formation by the media and means of transportation (Jackson, 1970; Reineck and Singh, 1975). Discussion textures include: grain size, sorting, roundness, shape, porocity, fabric
