Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite. A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter. Common rocks include granite, basalt, limestone, and sandstone. What rock makes phyllite? phyllite, fine-grained metamorphic rock formed by the reconstitution of fine-grained, parentRead More →
Andesite most commonly denotes fine-grained, usually porphyritic rocks; in composition these correspond roughly to the intrusive igneous rock diorite and consist essentially of andesine (a plagioclase feldspar) and one or more ferromagnesian minerals, such as pyroxene or biotite. What classification is andesite? Andesite is an aphanitic (fine-grained) igneous rock thatRead More →

An intermediate texture with some crystal face-formation is termed subhedral. Crystals that grow from cooling liquid magma typically do not form smooth faces or sharp crystal outlines. As magma cools, the crystals grow and eventually touch each other, preventing crystal faces from forming properly or at all. What is euhedralRead More →
Glass is a solid-like and transparent material that is used in numerous applications in our daily lives. Glass is made from natural and abundant raw materials (sand, soda ash and limestone) that are melted at very high temperature to form a new material: glass. Is glass technically rock? According toRead More →
Hornblende is a rock-forming mineral that is an important constituent in acidic and intermediate igneous rocks such as granite, diorite, syenite, andesite, and rhyolite. It is also found in metamorphic rocks such as gneiss and schist. Is hornblende a silicate mineral? Hornblende is a member of the amphibole group ofRead More →
The name of this mineral comes from an ancient Greek word for fire. Because of the bright yellow color of many examples of pyrite it sometimes is called “fool’s gold.” Pyrite is very common in the earth’s crust. It has been used as an ore for sulfur, and sometimes asRead More →
It is present in minute quantities in many minerals, notably monazite. However, it is only economical to extract it from uranium ore tailings and from the minerals euxenite, gadolinite and thortveitite. Most scandium not extracted from uranium tailings is mined in Scandinavia, Iceland and Madagascar. How is scandium obtained? ScandiumRead More →
