Sedimentary Rocks

Types of Sedimentary Rocks • Clastic • Chemical • Organic

SANDSTONE http: //www. beg. utexas. edu/mainweb/publications/gr aphics/sandstone. htm

conglomerate Made up of large sediments like pebbles and sand held together by Chemicals cementing the grains because pressure alone isn’t enough. http: //www. fi. edu/fellows/payton/rocks/expert/conglomerate. htm

Gneiss May have come from granite (an igenous rock) which underwent heat and pressure which flattened the grains. http: //www. fi. edu/fellows/payton/rocks/expert/gneiss. htm

Quartzite Made from quartz sandstone, this sample is from Georgia. hyperphysics. phy-astr. gsu. edu/. . . /quartzite. html
