what are the characteristics of limestone? | Yahoo Answers
May 12, 2007· Limestone is a sedimentary rock, formed by many years of intense pressure. It is softer than other rocks and is often confused with quartz and halite. It is rhomboidal, which means that anytime u smash it, it will always break off in the shape of rhombuses. It also reacts with hydrochloric acid...

Which characteristic is most common in sedimentary rocks ...
Nov 10, 2007· Sedimentary rocks can be categorized into three groups based on sediment type. Most sedimentary rocks are formed by the lithification of weathered rock debris that has been physically transported and deposited. During the transport process, the particles that make up these rocks often become rounded due to abrasion or can become highly sorted.

Chemical Sedimentary Rocks Windows to the Universe
Chemical Sedimentary Rocks Unlike most other sedimentary rocks, chemical rocks are not made of pieces of sediment. Instead, they have mineral crystals made from elements that are dissolved in water. The water in the oceans, lakes, and ground is often full of dissolved elements. All sorts of things can dissolve into water.

Lithic grains may be any finegrained or coarse grained igneous, metamorphic, or sedimentary rock. Although, the most commonly they are clasts of volcanic rocks. Accessory minerals make up a small percentage of the grains in a sandstone. They commonly include micas such as muscovite and biotite, olivine, pyroxene, and corundum, zircon, tourmaline, rutile, garnet, magnetite, or other dense, resistant .

What Are Five Examples of Chemical Weathering? | Sciencing
Apr 20, 2018· When carbon dioxide in the air dissolves in water, it forms carbonic acid. While carbonic acid is fairly weak, it can cause a form of chemical weathering known as carbonation. For example, calcite is a calcium carbonate mineral made up of calcium, carbon and oxygen.

NEWARK BASIN AND CONNECTICUT RIVER BASIN Hunter College
Both basins contain characteristic sedimentary sandstones and mudrocks that usually bear a red or brownish appearance from an abundance of iron oxide minerals (hematite and limonite). (Homes built of stone from the Newark Basin are called "brownstones.") Fossils are not abundant, but early Mesozoic dinosaur skeletons and trackways have been found.

limonite; unstable silicates will form clays. Minerals that are susceptible to physical weathering (, minerals that are soft or cleavable) will be reduced in size during transport, and so may only be identified under the microscope. Quartz is a common rockforming mineral, and resistant to both chemical and physical weathering.
