The distribution of dolomite rock textures indicates that porous zones were preserved as limestone until late in the diagenetic history, and were then subjected to late-stage dolomitization in a ...
In addition to rock material properties, and engineering classification of the rock mass has to take account of structure, discontinuities, and details of the weathering profile. Assessment of rock mass properties requires in situ testing to determine deformation characteristics.

Samples of carbonate rocks, both limestones and dolomites, were subjected to static hydrothermal tests to determine the extent to which mineral reactions affect petrophysical properties. Static tests were conducted in stainless steel autoclaves with porosity, permeability and pore-size distribution ...
Dolomite (/ ˈ d ɒ l ə m aɪ t /) is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO 3) 2. The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite.
The importance of classification for carbonates and mudrocks in engineering Matthew A. Perras & Mark S. Diederichs Queen’s University, Kingston, Ontario, Canada ABSTRACT
Milky quartz is a crystalline quartz that is white and translucent to almost opaque due to numerous evenly distributed gas and/or fluid inclusions. Specific Properties As inclusions in a crystal interfere with crystal growth, milky quartz crystals are usually twinned and sometimes also distorted.
Dolostone or dolomite rock is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO 3) 2. In old USGS publications, it was referred to as magnesian limestone, a term now reserved for magnesium-deficient dolostones or magnesium-rich limestones.

• Maybe considered an almost pure dolomitic rock con-sisting of 98% of mineral dolomite and 2% of calcite. Some silicate minerals (i.e. quartz) are present in trace amounts. • It has been formed by recrystallisation of pre-existing limestone with simultaneous or subsequent partial sub-
Amazonite Goddess Crystals. Amazonite honors the goddess Tiamat, the Sumero-Babylonian Mother and Chaos Goddess. She is the elemental powerful force of chaos that was split in two to form the heavens and earth, often depicted as either as a serpent or a dragon.
Pyrite Framboid: One of the most interesting crystal habits of pyrite is the "framboid." These tiny spheres of euhedral pyrite crystals are often found in organic muds, coal, shale, and other types of rocks.

Experimental work involving dolomite has focused on delineation of phase relations in dry and aqueous systems at moderate to high temperatures, determination of reaction pathways followed during dolomitization of calcium carbonate, and measurement of reaction rate.
Apatite is the main source of phosphorus. Phosphorus was previously extracted from crystalline Apatite, but nowadays is extracted from enormous deposits of Apatite-rich rock. Apatite is essential in the manufacture of phosphate fertilizers, and is very important in the chemical and pharmaceutical industries.
