What rocks have calcite in them?
Limestone and Marble have calcite in them.
Is calcite an igneous rock?
No, calcite is not an igneous rock. Calcite is a mineral that is commonly found in sedimentary rocks, such as limestone and marble, as well as in some metamorphic rocks. It is formed by the accumulation of calcareous remains of marine organisms.
What are all the names of all fluorescent rocks?
Some examples of fluorescent rocks include fluorite, calcite, willemite, and scheelite. These minerals contain trace elements that make them glow under ultraviolet light. There are many other types of rocks that can fluoresce as well.
What is calcite worth?
A calcite is worth around $20-$200 depending on the type of crystal. The calcite is found usually in rocks like limestone and it takes some years to form.
Is calcite metamorphic sedimentary or igneous?
Calcite is a mineral commonly found in sedimentary rocks. It can also be found in some metamorphic rocks, as it can recrystallize under heat and pressure. It is unlikely to be found in igneous rocks except in trace amounts.
How does calcite form?
Calcite is a common constituent of sedimentary rocks, limestone in particular, much of which is formed from the shells of dead marine organisms. Approximately 10% of sedimentary rock is limestone.
What are some examples of organic rock?
Examples of organic rocks include coal, which forms from compressed plant material, and limestone, which can contain fossilized remains of marine organisms like shells or coral. Another example is chalk, composed mainly of microscopic shells from plankton.

What are some examples of rocks that absorb odors?
Some examples of rocks that absorb odors include activated charcoal, zeolite, and lava rocks. These rocks have porous surfaces that can trap and neutralize odors in the air.
What rocks have white streaks?
Some possible rocks that can have white streaks include quartz, marble, and gypsum. White streaks can also be found in other minerals and rocks that contain light-colored minerals such as feldspar or calcite. The presence of white streaks in a rock can be indicative of certain mineral compositions.
What is a rock containing water?
A rock containing water is called a hydrous rock or a hydrated mineral. These rocks or minerals have water molecules trapped within their structure, which can be released through heating or other processes. Examples include gypsum, opal, and some types of clay minerals.
What are some examples of nonfoliated metamorphic rocks?
Examples of non-foliated metamorphic rocks are quartzite and marble.
