carbonate minerals

It is formed by the precipitation of carbonate minerals from water at normal temperatures.

There are carbonate minerals found on Mars, and dry ice in one of the polar caps.

Examples with 50 - 70% carbonate minerals are termed silico-carbonatites.

The skeletons and shells of many sea animals need what is known as calcium carbonate minerals.

This method produces the following colour differentiation in carbonate minerals:

Common carbonate minerals include calcite (found in limestone) and dolomite.

There is an effervescence, after carbonate minerals have been excluded by a test using hydrochloric acid.

But during the Cambrian period, some organisms used carbonate minerals for shells, so they had hard parts which could become fossils.

Thin-section studies of the granulites showed the absence of carbonate minerals.

Several reagents are available for etching carbonate minerals.

Synchysite is a group of carbonate minerals.

The city contains hot springs and travertines, terraces of carbonate minerals left by the flowing water.

Hydrolysis is a chemical weathering process affecting silicate and carbonate minerals.

It is a natural chemical precipitate of carbonate minerals; aragonite or calcite.

Researchers burned tiny samples of the meteorite at different temperatures to separate organic carbon and carbonate minerals.

Other carbonate minerals include aragonite (a rare form of ) and dolomite ().

Carbonate minerals are extremely varied and ubiquitous in chemically precipitated sedimentary rock.

For example, the presence of carbonate minerals suggests that the pH of the sediment on a site has always been above 8.

However, the early Earth may have had significant amounts of iron and carbonate minerals able to neutralize the effects of the nitrites.

Calcite and other carbonate minerals exhibit perfect rhombohedral cleavage.

The following list may include geographical sources of either natron or other hydrated sodium carbonate minerals:

Azurite is one of the two basic copper(II) carbonate minerals, the other being bright green malachite.

In geology, it is used as a stain to indicate the calcium carbonate minerals, calcite and aragonite.

Calcite, aragonite and vaterite are pure calcium carbonate minerals.

The carbonate minerals form the rock types: limestone, chalk, marble, travertine, tufa, and others.
