limestone | Characteristics, Formation, Texture, Uses ...

Limestone is a sedimentary rock made of calcium carbonate (CaCO 3 ), usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well. However, minor constituents of clay, iron carbonate, feldspar, pyrite, and quartz is also commonly present. In many cases, the grains are microscopic ...

Mudstone/Shale vs. Limestone

Thus, these are limestone nodules. Shales and mudstones quickly weather to create gentle slopes. The resistent bed on the right is a sandstone. The light gray, slope-forming, partially vegetated rock to the upper left is a mudstone. Go back to the Clastic Rocks page Return to Image Archive Home Page:

Sedimentary rock

Sedimentary rock - Sedimentary rock - Limestones and dolomites: Limestones and dolomites are collectively referred to as carbonates because they consist predominantly of the carbonate minerals calcite (CaCO3) and dolomite (CaMg[CO3]2). Almost all dolomites are believed to be produced by recrystallization of preexisting limestones, although the exact details of this dolomitization process ...

Indiana Limestone | Indiana Geological & Water Survey

Indiana Limestone, which is a Mississippian-age grainstone of very uniform texture and grade, has gained world-wide acceptance as a premier dimension stone. The Salem Limestone, which is the geologic formational name for this carbonate unit, crops out in a belt that trends southward from Stinesville in Monroe County to Bedford in Lawrence County.

What is limestone?

Limestone is an organic, sedimentary rock. This means it was formed from the remains of tiny shells and micro-skeletons deposited on the sea bed. Over the years this sediment was compressed to form solid rock. Limestone is formed in layers - called bedding planes. These bedding planes contain vertical cracks called joints.

Porosity and Bulk Density of Sedimentary Rocks

Average values for the porosity of sedimentary rocks have been given by Barrell (1914) as: shale, 8.2 percent; sandstone, 14.8 per­ cent; limestone, 5.3 percent; and all sedimentary rocks, 8.5 percent. Additional data since the publication of Barrell''s summary indicate that the average value of 8.2 percent for the porosity of shale may be low.


By oscil‐ lating solution and precipitation in the pores, lime mud could set into limestone on the sea‐bed. By more definite phases of solution, most of the limestone could be reduced to a marl bed with remains of undissolved limestone. ...

 · - 8% of crust volume is sedimentary rock. (Crust is 2.6 billion cubic miles or 1% of Earth volume.) - Thus continental sedimentary rock may be about 208 million cubic miles. - (21 million cubic miles of limestone exist if the often repeated estimate is correct that limestone makes up 10% of sedimentary rock.)
