(quartz), found at Hohentor, along the Hochalpenstraße.
Was actually looking for Pb-Zn mineralization, but not a bad consolation prize.

Who needs the Las Vegas Sphere when you can have the hematite orb?

Minerals with this globular form - which can resemble a bunch of grapes when many lumps occur together - are described as having a botryoidal habit. This comes from the Ancient Greek word βότρυς/bótrus, which means a bunch of grapes

Image 1:Piece of ore from Carinthia. Image 2: underground in the mine, the shiny Grey are the ore seams.
The ore is composed of dark Grey bladed hematite ( in English/ auf Deutsch) and also contains pyrite (the yellow mineral in image 1). This ore is actually used as an industrial mineral and is the basis for rustproof paints, esp those used to on iron bridges. Can't rust that which is already rust😎

Calcite appreciation - awesome calthemites in the Falkirk Tunnel 🖤 The tunnel cuts through carboniferous bedrock including limestone, and these secondary deposits have now been forming for over 200 years. It’s also the longest canal tunnel in Scotland at 630m long! 🏴󠁧󠁢󠁳󠁣󠁴󠁿
Another fun fact is that a couple of the navvies involved in building the Falkirk tunnel went on to become two of Scotland’s most notorious criminals.. Burke and Hare! ☠️

I talk a little about mini thundereggs and share some photos of roughly Brazil-nut-sized thunderegg geodes that we cut and polished. Friend link (no paywall): medium.com/amethyst-dreams/poc

I struggle to photograph the stones I polish. If anyone has links or descriptions of how they set up to photograph gems, jewelry, mineral, stones, or maybe even any products that are somewhat transparent/translucent, I would love to see them.

This photo was used to illustrate my Medium article on the lore behind this stone

Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from 800 to 1,200 °C (1,470 to 2,190 °F). The volcanic rock resulting from subsequent cooling is also often called lava.
