That was a tough match but #TeamQuartz managed to pull through in the end! Thank you for voting for the best mineral and goodbye cinnabar 👋 #MinCup23 #geology #mineral #minerals

two outcrops with quartz veins that seem to be related to slickensides (bedrock cracking and two pieces slide past each other)

oh i forgot. what is the relationship between quartz vein and slide? does quartz fluid help the rock slide? does it come in after the slide? (but then the 'slick' mineralization wld be destroyed?)

#quartz is nice and I'm glad for crystal derived time, but I voted #cinnabar. Quartz is omnipresent, but the trip with single digit aged me and my dad and the guide to Obermoschel was unique. I'm working with quartz for clock signals, have some nice oscillators (Rb Controlled, heated) but my picture shows an old russian low frequency quartz bar I'm didn't come around to use yet. #mincup23 #teamquartz

This large amethyst geode is on display in the National Museum of Scotland in Edinburgh. It formed 130 million years ago when there was intense volcanism in Brazil. Enough lava was produced to cover the British Isles in 3.2 km of lava flows. Amethyst then crystallised in cavities in the solidified lava

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

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!

#TeamQuartz #MinCup23 #minerals #mineral 8/?

The quartz inside the oscillator is shaped like a tuning fork and when a current passes through it, it vibrates at a frequency of 32,768 Hz (32,768 times a second). The circuit in a watch/clock counts the number of quartz vibrations and uses it to generate a regular electrical pulse at a rate of one per second. This then powers the gears or the LCD display in the watch/clock

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

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/?
