Britain wants Ukraine’s minerals too

It’s not just Trump. The UK views critical minerals as a government priority and wants to open up Ukraine’s vast resources to British corporations.

Antibiotic resistance can spread unpredictably into the environment, living on mineral surfaces

Imagine one of Denmark's many picturesque beaches, the waves lapping against the shore, the golden sand and the smooth pebbles. That sounds like a beautiful moment in time. But under the surface, there is more to the story.

DR Congo conflict: What is the fighting in Goma about?

M23 rebels have made rapid advances in the latest bout of conflict that has long-dogged the mineral-rich east.

I've been falling behind with my #MinCup23 tweets 😬 Today's match is arsenuranospathite vs neptunite and the latter is getting my vote. It's a silicate #mineral named after Neptune, the Roman god of the sea. It's often found together with white natrolite, and they look so good together! Here's one on display in the NHM London

An elongate slab of rock with a bumpy coating of white natrolite which resembles snow. There are black pointy crystals of neptunite of varying sizes spread across the natrolite.

Round 1 Match 14

This match is all about friendship: Arsenuranospathite flirts with danger by wrapping radioactive uranium, poisonous arsenic, and touchy fluorine in its watery embrace, while tall, dark, and opaque Neptunite lurks in the shadows with its BFF, 2019 Mi…

Amethyst is a purple variety of quartz whose colour is caused by iron replacing silicon and then exposure to gamma radiation. Its name comes from the Greek amethystos (not drunk) - it was thought that amethyst could cure drunkenness 🥴 #TeamQuartz #MinCup23 #minerals #mineral @MineralCup 10/?

Quartz often contains inclusions of other minerals, such as this rutilated quartz glowing in the morning sunshine in the NHM London Mineral Gallery 🌟

A hexagonal crystal of quartz filled with golden needles of rutile. There are so many rutile needles inside, it almost looks like a mass of golden hair. Label text: Fine bronze needles in quartz (Venus hair stone). Piz Aul, Switzerland.

It’s time for familiar favourites! Do you prefer the ominous scarlet of Cinnabar, or the familiar charm of Quartz? One needs to be handled with care, while the other is the cornerstone of every childhood rock collection. Which will it be?

This website provides a great summary of how quartz clocks work: http://explainthatstuff.com/quartzclockwatch.html

So remember, whenever you check the time, you should thank the tiny little quartz crystal vibrating thousands of times a second!

A quartz oscillator is used to regulate time inside most watches and clocks. This is because quartz is piezoelectric, which means that when it’s squeezed, it generates an electric current. This also works the other way round too: when an electric current passes through it, it vibrates at a certain frequency. The quartz oscillator is circled in the picture below

Just look at all the detail you can carve into quartz! This is the Lothair Crystal, a 11.5cm wide piece of rock crystal engraved with scenes from a biblical story

Art lovers! Vote quartz! There's a long history of quartz being carved into beautiful pieces.

Have you ever visited a museum or gallery and seen something carved out of rock crystal? Well that's just a colourless variety of quartz. This is a Fatimid (#Egyptian) jug carved from quartz, late 10th to early 11th century

I know many people are upset ice didn't make it into #MinCup23. Well, why not vote #TeamQuartz? The oldest name for quartz is the Greek word κρύσταλλος (kristallos) which was first used 300-325 BCE. Kristallos means cold - it was believed that crystals were a type of ice that couldn't melt because it was made by the gods ❄❄❄

A fact for the #etymology nerds! The word quartz describes one of its physical properties. It comes from the German word "Quarz" which has origins in various Slavic words for "hard" (e.g., Czech "tvrdý", Polish "twardy", Serbian/Croatian "tvrd"). Quartz is a pretty hard mineral as it's 7 on the Mohs hardness scale

The Mohs hardness scale. The left column shows the hardness of minerals: Talc is 1, gypsum is 2, calcite is 3, fluorite is 4, apatite is 5, orthoclase is 6, quartz is 7, topaz is 8, corundum is 9, diamond is 10. The right hand column shows the hardness of various everyday objects: A fingernail is 2.5, a copper penny is 3.5, a knife/glass plate is 5.5, a steel nail is 6.5, a masonry drill bit is 8.5.

Cinnabar has a slight lead over quartz and I'm not happy about that! This is the start of a *long* thread for #TeamQuartz which I'll be updating throughout the day.

Quartz is my all time favourite mineral. Despite its simple formula (SiO2), it can be found in a variety of colours and morphologies 1/?
