The Life Story of a Mineral Specimen
Chrysocolla is a secondary mineral of copper, yielding from a chemical reaction that takes eons to take place. It is most commonly found in veins, or growing in what is known as “botryoidal” habit: appearing bubbly and bulbous in nature. This particular specimen is a geode, or perhaps a vug; both of these are small pockets in solid stone where crystals have room to grow, rather than becoming concretions between rock layers.
This specimen appears to most likely be stalactites: rock formations made by drops of water seeping through the rock, taking mineral deposits with them, and leaving trace amounts of the mineral behind as it drips down. Over the course of centuries, these deposited minerals form thee stalactites you see there. What makes this specimen most interesting is that semi-translucent layer that covers the sky-blue Chrysocolla; this appears to be Quartz.
What would cause this change to occur? Several factors may have come into play, but the general cause was a change in mineral content in the water seeping through the rock. At the time of the Chrysocolla deposits, water - perhaps with a slight acidic content - was passing through a copper vein. Maybe the copper eroded away, or maybe water came from a different direction or through different rock; a rock rich in silicate material. If you’ve ever looked closely at sand, you’d have noticed the transparency of most of the grains. This is silica, the same substance Quartz is made of.
So, as the water sank through the rock and passed over the Chrysocolla stalactites, it encrusted them with beautiful translucent Quartz. At some point in time, the water flow stopped, ceasing the growth of the stalactites. This could have been hundreds or thousands of years ago, or as recently as it was mined.
Essential Guide: The Bioluminescence Edition
Bioluminescence — the ability for organisms to generate their own light — has evolved independently at least 50 times. All around the world, oceans glow, trees sparkle, and the forest floor flashes. It may be difficult to see many of these phenomena, but take a tour with us through the land, air and sea as we survey one of nature’s most awe-inspiring spectacles.
National Geographic Traveler Photo Contest
Round up of just some of the many beautiful photos submitted to the contest. If you think you’ve got what it takes, you have until June 30th to enter and win a once-in-a-lifetime trip to the Galápagos Islands.
This is one of the types of homes I am strongly considering because just look at house beautiful and amazing this is.

Sweden did a thing.
literally this is all i ask for out of life. i don’t need more than this.
I so wish I could do this in gold and silver foil on the jacket of a hardcover. Maybe in 10 years? For now, this is probably an element of the back cover on the paper book + interior graphic. Tomorrow, the last chapter of the free version of Hunters Unlucky posts to my website. The whole thing comes down when the ebook gets released, which will happen before Christmas. If you wanted to read the free typo-rich version, you’d better start soon. If you were holding out for the more polished, typo-poor model, we’re closing in. Audio book next year.
Oh hey, I can reblog some of the art I did! Abbie Hilton’s an awesome recurring commissioner; I’ve done covers for both her Prophet of Panamindorah and Cowry Catchers series.
