Last in my multicoloured beach series: pink! 💕

Up next in my multicoloured beach series: red! 🖍
.
Gozo has two main red sand beaches: Ramla l-Hamra (this pic) and San Blas (swipe to see).
.
Depending on the time of day and sand wetness, their colour can vary between a burnt orange to a muddy red. And somewhat ironically, this colour comes from greensand.🧤
.
Greensand is one of Gozo’s five rock types, rich in iron and normally found sandwiched between other rock layers. But when exposed to the air, the iron reacts with oxygen, forming red iron oxides. (The same chemical family as rust.) 🌡

Purple sand! 💜
.
Continuing my series of multicoloured sandy beaches, this is Pfeiffer Beach in California. This beach is like ice cream ripple - golden sand interrupted by unexpected swirls of purple.
.
The purple sand comes from the cliffs above, which contain a group of purple minerals called manganese garnets.

Not a black and white filter❗️This is Reynisfjara, Iceland’s most famous black sand beach. Visit on an overcast day and all colour can bleed away.
.
🌋Iceland’s coast is full of black sand beaches, which all formed similarly. Hot lava pouring out of one of Iceland’s many volcanoes met the Atlantic Ocean, cooling instantaneously and shattering into basalt pebbles. These have been slowly weathered over time into smaller and smaller pieces, forming sand.

☠️ Show stopper! ☠️
.
Not only beautiful - the passion flower can stop you in your tracks thanks to another reason. Its leaves contain cyanide, a chemical that’s poisonous to much of the animal and insect world.
.
It’s part of a brilliant evolutionary strategy that stops it from being eaten.

Gold mining step 4️⃣ - the final products! . 1

Gold mining step 4️⃣ - the final products!
.
1st pic: Geology on a chain 🙂 - this is a gold nugget, left in its natural form after being mined.

2nd pic: Arrowtown, one of the villages that grew around mining. Many who didn’t strike it rich still carved out a life from the related economy (hotels, restaurants, banking, prostitution) and this mass immigration and thriving economy shaped modern New Zealand. 💰
.
3rd pic: Unfortunately racism was alive and well. Chinese miners were ostracized, living on the periphery in each mining village in much worse conditions. 🏚

Gold mining step 3️⃣
.
Here’s where the chemistry comes in ⚗️
.
This apparatus was used to extract any gold out of crushed quartz rocks. ⚜️
.
Cyanide and water were added in. The basic chemistry behind this is that cyanide in a water solution draws the gold out from the rest of the rock, as this solution takes electrons from the gold atoms. 🤝
.
This loss of electrons makes the solid gold dissolve in the water, leaving other rock components stuck behind.💦
.
Addition of zinc metal to the separated liquid then causes an inverse process. Gold takes electrons from the zinc, re-becoming a solid and depositing out of solution, ready for the taking. (The zinc dissolves in its place.)💰

Gold mining step 2️⃣
.
This is a stamper battery from the 1860s. Used to crush the mined rock into smaller pieces, so that gold could then be extracted more easily.💰
.
All that water splashing out of the bottom is thanks to the whole setup being powered by water, pumped up from the gorge nearby. 🚿

Gold mining, step 1️⃣
.
The first step to getting to gold in hard quartz rock was tunneling. ⛏💣
.
This is part of the tunnel in Karangahake, accessible as part of a hiking route in the area. Pitch black and claustrophobic, I was happy to eventually find myself on the other side.🔦
.
Would you work here day after day in the hope of striking it rich? In its heyday, this was New Zealand’s third largest mine, with 2000 people living directly on site.💰💰

What would you do to own this rock❓
.
This is quartz naturally dripping with shimmering gold. A sight that would have greeted many prospectors at the height of New Zealand’s gold rush. 💰 💰 .
There were two ways of striking it lucky during the gold rush:
1️⃣ finding gold in the veins of hard quartz rock
2️⃣ finding it loose in the river bed.
.
Getting to gold trapped in hard rock like this required a simple blend of physics and chemistry.
.

What’s your daily commute❓
.
This used to be gold miners’ daily commute in New Zealand, back in the 19th century.
.
Thanks to COVID-19, mine is still rolling out of bed and onto my desk. Altogether less treacherous, but then there isn’t a potential gold nugget waiting at the end of it!

Today is World Penguin Day, so I thought I’d post about some rather special penguins seen in New Zealand. 🐧🐧
.

They’re not the stereotypical penguin. Blue-gray with white bellies – they’re about the size of an A4 sheet. In fact they’re the smallest species of penguin known, found naturally only in New Zealand and Australia. (Scientific name: Eudyptula minor)
.

A quick visit to Malta’s oldest known Carob tree

A quick visit to Malta’s oldest known Carob tree. 🏃‍♀️ .

If you’ve followed me for a while, you’ll know that I’ve already posted about this Carob. But I needed some reassurance in the beauty of nature in these weird times, and thought I’d share to help anyone feeling the same. ❤️
.

This Carob tree is thought to be over 1000 years old. Still, it’s a far cry from the oldest tree in the world, known to be over 5000 years old, situated in the United States’ White Mountains. ⛰ .

Yet again, this doesn’t come close to the age of some known clonal trees - trees that clone themselves off a single root system. 🌳🌳🌳
.
The oldest of these clonal systems is thought to be a mind-boggling 80,000 years old. 😲
.
Maltese name: Harruba
Scientific name: Ceratonia siliqua .

Life finds a way 💛
.
These tiny flowers may look like Chamomile, but they’re actually a species found only in Malta, similarly called Maltese Sea Chamomile.
.

The plant grows in tiny pockets of salty soil by the Maltese coastline.

Species name: Anthemis urvilleana
Maltese name: Bebuna tal-Bahar
