Q:

What is dolostone?

A:

A dolostone or dolomite rock is a former limestone wherein the calcite is replaced by dolomite, according to About.com. Geology.com states that this is a type of sedimentary rock found in sedimentary basins all over the world.

Dolostone and limestone have many similarities. Both types of rock have the same color ranges of white-to-light brown and white-to-gray. Other colors, including green, black and red, can occur. Additionally, both types of rocks are similar in terms of hardness, and both of them can be dissolved in dilute hydrochloric acid. Dolostone can be crushed and used for construction purposes and to neutralize acids.

  • Q:

    How is dolostone formed?

    A:

    According to About.com, dolostone refers to rock that is composed primarily of the mineral dolomite, which forms when calcite limestone is altered underground. This chemical change, called dolomitization, results in a reduced volume and recrystalization of the stone, making it more porous. This process is not fully understood by sedimentary geologists.

  • Q:

    How is sandstone formed?

    A:

    Sandstone forms over the course of centuries, as deposits of sand accumulate in rivers, lakes or on the ocean floor, and the sand blends with calcite or quarts and then undergoes compression. After enough time goes by, the pressure pushes all of these elements together to create sandstone. Because not all sand is identical but instead comes in a variety of colors and grain textures, each formation has a unique appearance.

    What is the first step of the lithification process?

    A:

    According to About.com, the first step of the lithification process is compaction. This step involves the squeezing of sediments into a smaller volume by making the particles more closely packed, by eliminating water from the pore space or by pressure solution at contact points.

    What is manganese used for?

    A:

    Among the important industrial uses of manganese, according to About.com, is its addition to alloys to improve the hardenability, hardness, stiffness, strength, toughness and wear resistence of steel. When added to steel with antimony and aluminum, it forms ferromagnetic alloys, especially when the alloy includes copper.
