The calcite is basically floating in solution around the shell, and it deposits on the shell like a forming crystal.
The name calcite (Lat. _calx_, _calcis_, meaning burnt lime) is of comparatively recent origin, and was first applied, in 1836, to the
The latter mode of origin is suggested by the frequent occurrence of calamine pseudomorphous after calcite, that is, having the form of calcite crystals.
In such cases the cleavage of one stone is often of paramount importance in testing the cleavage of another, as is seen in the perfection of the cleavage planes of calcite, which is used in the polariscope.
The research works by using a naturally forming crystal called calcite which has extraordinary light bending abilities.
The ancient skeletal fossils are made not of bone, but of calcite, which is the same material that makes up the rock matrix in which they are embedded.
The stone lets out a chemical called calcite which means that the building stays white even when exposed to the elements.
They may see colors that are due to other minerals such as calcite, which forms hard pan or caliche in the -- in certain parts of the U.S. and which is deposited, in most cases, by water.
Another form of calcite which is to be sparingly found is what is called dogtooth spar, having the form shown in Fig. 4.
Some of the dissolved substances of weathering, such as calcite, quartz, and iron oxide, are carried down and deposited in openings of the rocks, where they act as cements.
