Sandstone Sandstone is a sedimentary rock composed mostly of quartz sand, but it can also contain significant amounts of feldspar, and sometimes silt and clay Sandstone that contains more than 90% quartz is called quartzose sandstone When the sandstone contains more than 25% feldspar, it is called arkose or arkosic sandstoneIn the dimension stone industry, diorite is sold as a "granite" The dimension stone industry uses the name "granite" for any rock with visible, interlocking grains of feldspar This simplifies discussions with customers who do not know how to identify igneous and metamorphic rocksDiorite: Igneous Rock Pictures, Definition & More Geology
