Fuller's Earth is a rock made up mainly from the minerals montmorillonite and/or palygorskite (attapulgite).
The word you are looking for is "vein." A vein is a deposit or mass of a particular mineral embedded within a rock or the Earth's surface.
Quartz is a mineral primarily made up of silicon and oxygen. It is the second most abundant mineral in the Earth's continental crust and is commonly found in igneous, metamorphic, and sedimentary rocks.
The most common mineral found in rocks is quartz. Quartz is a mineral composed of silicon and oxygen atoms in a continuous framework of SiO4 silicon–oxygen tetrahedra, making it abundant in the Earth's crust.
It is both. The metal gold exists as a mineral in the Earth, and its distinctive colour is used to describe the colouring of other objects. A similar thing happens with orange, the colour and the fruit.
Quartz is a mineral consisting of silicon dioxide (SiO2) and is not classified as a rock on its own. It is one of the most abundant minerals in the Earth's crust and can be found in various types of rocks, including granite, sandstone, and quartzite.
