Graphite:
- Composed of carbon
- Same composition as diamond but a different structure
- Forms in metamorphic/igneous rocks & meteorites
- Used in electrical conductors, lubricants, pencils
- Its name comes from the Greek "γράφειν/graphein" (to write) #minerals #MineralMonday

Topaz:
- Silicate mineral
- Pure topaz = yellow, brown, blue
- Impurities & treatments cause other colours
- Blue topaz is the Texas state mineral
- Forms in pegmatites, quartz veins & granite
- Named after Topazios Island (now called Zabargad Island) in the Red Sea #minerals

Periclase:
- A magnesium oxide mineral
- Forms via high temperature contact metamorphism
- Used in the production of fire bricks
- Its name comes from the Greek word "περικλάω/perikláo" (to break around) because of its cleavage #minerals

Nepheline:
- A feldspathoid mineral
- Forms in volcanic rocks with low silica content
- Its name comes from the Greek word "νεφέλη/nephélē" (cloud) because it turns cloudy when exposed to strong acid #minerals

Oligoclase:
- A plagioclase feldspar mineral
- Sometimes classed as a variety of albite
- An important component of igneous rocks
- Its name comes from the Greek words "όλίγος/oligos" (little) and "κλάσις/klasis" (fracture) because of its cleavage #minerals

Albite:
- A plagioclase feldspar mineral
- Forms in felsic igneous rocks
- First discovered in 1815 in Finnbo, Falun, Sweden
- Its name comes from the Latin word "albus" (white) because of its colour #minerals

Monazite:
- A phosphate mineral series with species rich in cerium, lanthanum, neodymium, samarium or gadolinium
- Radioactive due to thorium and sometimes uranium
- Its name comes from the Greek word "μονάζειν/monázein (to be alone) because of its isolated crystals #minerals
