Embarking on an adventure deep within the heart of Tetouan's mountains, I stumbled upon this breathtaking view from inside a majestic cave. 🏞️ The landscape unfolds before me, revealing the city of Tetouan nestled below, while the sky stretches endlessly above. 🌄 From the rugged formations to the lush greenery, every element speaks of the wonders of nature. 🌿☁️
Misery Bay on Manitoulin Island in Ontario is renowned for its alvars and large dolomite pavements. These flat slabs of stone were ground flat by glaciers during the last ice age. The area was covered by the Laurentide Ice Sheet 20,000 years ago and was only exposed 10,000 years ago. The land has been gradually rising since then, as it is no longer weighed down by the glacier
Field work chic 🏕🪨⛏ This last field course I was on was honestly very life fulfilling. Went into it not knowing anyone- afraid it would be social agony the whole time. Ended up making amazing friends, saw some awesome geology and solved some great puzzles. 5 stars, would recommend. #gay #stem #geology #geologyrocks #minerals #geoscience #school #gayboy #gayguy #cabin #lodge #camping (at Kaladar, Ontario) https://www.instagram.com/p/CdrLwV6u9I0/?igshid=NGJjMDIxMWI=
Zoisite (Var.) Tanzanite Merelani Mines, Arusha, Tanzania 3.5 cm x 1.6 cm x 1.3 cm. Cut stone 2.8 carats. Jeff Scovil photo. Beautiful unheated gem tanzanite crystal with (God forbid) considerable 'gem rough' within the crystal that would cut larger stones than the example provided here. There is no damage to the crystal other than the contact at the bottom from extraction. First recognized in the year 1967, the stone is rare in the terms that it is only found in one mine near Mt Kilimanjaro, in the country of Tanzania. This is the only mine in the world that produces gem tanzanite crystals. Tanzanite is 1,000 times rarer than a diamond; the stone is expected to be completely mined out in the next couple of decades, which further increases the rarity of the stone. Tanzanite is in the top 10 rarest minerals on earth. Tanzanite has the mineralogical attribute to be trichroic and appears different colors in different lighting at different angles of the axis. Tanzanite was formed 585 million years ago. Many people are of the opinion that tanzanite’s colors are superior to sapphire. #tanzanite #tanzanite #tanzanite #Crystal #gemstone #rockhounds #rockhounding #geology #geologist #gemologist #mineralshow #minerals #naturalgemstone #instacrystals #crystalshop #gemshop #crystals #gemstones #gemporn #mineralporn #crystalporn #geologyrocks #fineminerals #finegemstone #crystalline #geologypage #metaphysical https://www.instagram.com/p/Co5n9BnP1fc/?igshid=NGJjMDIxMWI=
De loin comme de près au Pac National du Bic de la SEPAQ, tout est beau. Des photos de pierres, de roc et de formations rocheuses de toutes sortes sont magnifiques dans ce parc. . #mineral #mineraly #mineralogy #earth #geologia #geologist #geologyrocks (à Parc national du Bic) https://www.instagram.com/p/CkOJeDYu4Rh/?igshid=NGJjMDIxMWI=
These rocks have all experienced hydrothermal alteration and contact metamorphism. The 1.4 billion year old Velkerri Formation from Australia is an organic rich mudstone. Some time after burial and lithification, the rock was intruded by hydrothermal fluids that caused metallic sulphide, and ferrous carbonate + quartz mineralisation. I think some maybe related to the intrusion of dolerite around 1.2 billon years ago, and some related to basin inversion around 800 million years ago. The mineralisation and contact metamorphism is widespread but in some areas is subtle and only visible on the microscopic scale. The velkerri formation is the basis for much of what we know about marine chemistry during the early evolution of eukaryotic life. Several important geochemical studies sampled the velkerri formation and used the pyrite in particular to show that the oceans 1.4 billion years ago were low in oxygen and rich in sulphur. This environmental state is thought to have been a major barrier to the development of more complex eukarotes. However, the hydrothermal and contact metamorphic alteration, in particular the micro scale alteration were unknown when these studies were conducted. As these previous studies used bulk sampling methods, it's likely that they unknowingly sampled the later sulphides which will have influenced the results and the interpretations of the previous researchers. This does not mean the previous work is bad and should be disregarded. Simply that the results should be reinterpreted inlight of this new information. That is how science is supposed to work. It is self revising and correcting. That is how science advances and improves. However, getting paper reviewers to understand and accept this is another thing entirely. I'm currently revising this work after a rejection. So let's see if the next version is enough to get the paper out. 😉 #geologyjohnson #geology #geologyrocks #pyrite #blackshale #shale #ore #hydrothermal #igneous #dolerite #metamorphism #science #sciencerocks #earthscience #naturalhistory https://www.instagram.com/p/CdaMy8-sFoZ/?igshid=NGJjMDIxMWI=
Look at the colors in this piece of raw petrified wood! The rich red, orange, and earth tones make this a stunning sacred stone that is ideal as an altar piece, collector's piece, or focal point for meditation and manifestation. This piece comes from our homestead in the Arizona high desert. It was found, cleansed, and anointed with my Shaman Stone Ritual Oil.

The newest group of yarns in my gem and mineral project: Hematite- Merino and sparkle (?) by @mohairandmore plied with black Merino from the same Opal- Merino and sparkle “Happily Ever After” also from @mohairandmore plied with white Shetland Chrysocolla- dyed mystery locks from a guild member cable plied with black Merino. I may do a third group although at the moment I only have one more design in mind so I may make that one and call this project finished. Now I just need to figure out what I’m doing with all these yarns! #handspunyarn #merino #shetland #minerology #geologyrocks #chrysocolla #hematite #opal #druidry #witchesofinstagram #gaydruid https://www.instagram.com/p/CnzaU2yupSf/?igshid=NGJjMDIxMWI=
