KGS--Kansas Rocks and Minerals--Kansas Rocks

Of the three main types of rocks, sedimentary rocks are by far the most common in Kansas. In fact, nearly all the surface exposures of the state consist of this type. The exceptions are several small areas of igneous rocks in Riley County and two areas of igneous and metamorphic rocks in Woodson County.

Classification of Sedimentary Rocks

Usually white or pink in sedimentary rocks. Cleavage. H=6 (Scratches glass). There's so much feldspar in the Earth's crust that a lot of it gets buried in sediment before it breaks down to clay minerals. Calcite: Most often white or gray, but can be any color. H=3 (Softer than glass). Reacts vigorously (effervesces) with dilute HCL.

White materials mixed with red produce pink rocks. Black sedimentary rocks are due to the carbonaceous material remaining after the decay of organic matter. On chemical weathering a grey limestone becomes buff, yellow or red. This is because iron minerals were included with the calcareous materials when the limestone was deposited.
