Table 1 lists some of the common rock types and their typical content of potassium, uranium, and thorium. Potassium is an abundant element, so the radioactive K 40 is widely distributed (Table 2). Potassium, feldspars and micas are common components in igneous and metamorphic rocks. Immature sandstones can retain an abundance of …The three, most common, chemical cements in sedimentary rocks such as sandstone are silica (quartz), calcium carbonate (calcite), and the iron oxides. What are the three types of sandstone? Sandstone is categorized into three main types based on their variation in composition and cementing material, they include: Quartz Sandstone. Arkose.Breccia – Rock composed of broken fragments cemented by a matrix. Calcarenite – Type of limestone that is composed predominantly of sand-size grains.

Sandstone, and siltstone are examples of clastic sedimentary rocks. Chemical sedimentary rocks: These rocks are formed from the dissolved materials that precipitate from the ... Limestone is a relatively soft rock with a Mohs hardness of 3, which means it can be easily scratched. It has a specific gravity of 2.7-2.9, which makes it less dense than most other rocks. It is typically soluble in acidic solutions, which is why limestone landscapes often feature caves, sinkholes, and other karst formations. Type of LimestoneSandstone 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 sandstone.There are three main types of sedimentary rocks: mudstone, sandstone, limestone.
