In conclusion: The ores of primary formation in the Tintic mines have been, in most of the occurrences, deposited from highly heated solutions by the metasomatic replacement of the limestone; only in relatively subordinate amount have the metallic sulphides been formed by crystalline growth in the rock, or by crystallization in the interspaces of the orebodies.

4/9/2018· Limestone is formed partly by chemical processes and partly biological process. Most limestone is composed of skeletal fragments of marine organisms such as coral. Pure limestone is white or almost white, but because of impurities, such as clay, sand, organic remains, iron oxide and other materials, many limestones exhibit different colors

Examples. Calcium carbonate (limestone or chalk) decomposes into calcium oxide and carbon dioxide when heated. The chemical reaction is as follows: CaCO 3 → CaO + CO 2 The reaction is used to make quick lime, which is an industrially important product. Other example of thermal Decomposition is : 2Pb(NO 3) 2> 2PbO + O 2 +4NO 2. Some oxides, especially of weakly electropositive metals

Laser Chemical vapor deposition (LCVD) This CVD process uses lasers to heat spots or lines on a substrate in semiconductor applications. In MEMS and in fiber production the lasers are used rapidly to break down the precursor gas—process temperature can exceed 2000 °C—to build up a solid structure in much the same way as laser sintering

Evaporation is a common method of thinfilm source material is evaporated in a vacuum allows vapor particles to travel directly to the target object (substrate), where they condense back to a solid state.
WhatsApp Limestone can form entirely without the help of organic material. In warm climates, calcium carbonate can become concentrated in seawater. As it reaches a critical point, it begins to precipitate out in tiny grains the size of sand. Since sedimentary rocks are the result of a sequential process of erosion and deposition, we can often find a

Although hydrothermal mineral deposits may form in any host rock, deposition is preferentially influenced or localized by certain kinds of rock. For example, leadzincsilver ores in some parts of Mexico occur in dolomitic rather than pure limestone; the reverse is true at Santa Eulalia, where massive sulfide deposits end abruptly at the
