The appearance and type of mineral crystal appearing in a rock is dependent on the type of rock and the method by which it is created.
it is a metamorfc
Sometime in pre-history.
Pink crystals found in granite are usually orthoclase feldspar. These crystals give granite its pink to reddish color and are one of the main components of the rock.
Large crystals found in a fine-grained rock can indicate that the rock cooled slowly, allowing the crystals to grow larger. This slow cooling process typically occurs deeper within the Earth's crust where temperatures are higher. The presence of large crystals in a fine-grained rock can also suggest that the rock underwent metamorphism, changing its original composition.
Intrusive Rocks are found underneath Earths crust, while Extrusive rocks are found above Earths crust.
Intrusive rock normally has visible crystals. Extrusive igneous rock has small crystals. A black extrusive igneous rock with small crystals could be basalt.
The mineral orthoclase is found all over the world. It can also be found in Granite rock. It would be the pink or white crystals in it.
It is conceivable that a fossil could be found among sedimentary rock crystals, and some dead organisms have actually been replaced by minerals which are composed of crystals. Fossils in gems and crystals from metamorphic or igneous processes--no.
The size of the crystals is a function of the rate of cooling of the molten rock. The faster the molten rock cools, the smaller the crystals will be.
The rock with crystals inside in can be igneous rock, but no, idk about the minerals.
The crystals in a rock are often referred to as mineral crystals. They are formed as the molten rock cools and solidifies, allowing minerals to crystallize and grow within the rock. The size, shape, and arrangement of these crystals can provide clues about the rock's formation and history.
In general, sedimentary rock crystals would be crystals that are found in sedimentary rocks. Normally they are calcite or quartz as they are the minerals most likely to cement sediments to form sedimentary rocks. There is a group of sedimentary rocks called evaporites that include crystals of salt, gypsum, sylvite, glauberite, thenardite, mirabilite and a few others. However, there is a tremendous variety of other minerals that can produce crystals in sedimentary rocks. Geodes from Indiana, Illinois, and Kentucky can have crystals of barite, millerite, sphalerite, galena, fluorite, and aragonite. In other areas of the planet crystals of azurite and malachite can be found in sedimentary rocks. There are many, many other types of crystals that have been found in sedimentary rocks.
