Limestone can be bio-clastic or non-clastic in origin. ♦ Clastic texture: grains or clasts do not interlock but rather are piled together and cemented. These type of rocks originate and are transported as solid particles from both mechanical and chemical weathering. Clastic sedimentary rocks The fragments of pre-existing rocks or minerals that make up a sedimentary rock are called clasts. This sandstone rock (left photo) has a clastic texture. Clastic Texture: Clastic rocks consist of the solid particles from preexisting rocks. Limestones and dolostones (dolomites) make up the bulk of the nonterrigenous sedimentary rocks. (i.e transporting agent, depositional environment, energy of the transporting agent): an agent of mechanical weathering in the form of blowing desert sand (). Boundaries of individual grains may be another grain, cement or empty pore space. Overall rock is generally porous and not very dense. Because clasts are only cemented together, grains are relatively easy to “scrape off" using a rock hammer point or metal nail. Sedimentary rocks made up of clasts are called clastic (clastic indicates that particles have been broken and transported). Carbonate rocks: limestones and dolomites. Clastic minerals or rock fragments: quartz sand, feldspar, silt, and clay history of this rock. Claystone Clastic texture This clay-rich rock has some gritty sand particles, but is predominantly clay. Quartz Sandstone Clastic texture This rock is a well-cemented fine-grained sandstone. When lithified, they form clastic sedimentary rocks. Sedimentary Rocks Lab 1) Rock: Quartz Sandstone Texture: Clastic; Medium-grained Sorting: well sorted clastic, chemical, biochemical or organic? Wet the rock and feel how it turns gooey. What are clasts? Clastic sedimentary rocks are primarily classified on the size of their clasts. Limestones are for the most part primary carbonate rocks. Clasts are rock fragments, also pieces of rock that make up the texture of some sedimentary rock (clastic sedimentary rock).
