After securing the victory, our winner talked a bit about her love for rocks and thoughts about the #awesomecrystalsbattle : “Thanks! This was fun!
“So I have always had a love of rocks and can't resist putting some in my pocket from everywhere I go.
“Grape agate has been on my wish list for a long time and I got this piece for my birthday this year! It seemed contest worthy to me...and rightfully so I guess 😃
“thanks for a fun way to show it off!”

A Turkish court has annulled the museum status of Hagia Sophia in Istanbul, which will enable it to return to being a mosque. Built 1,500 years ago, the Unesco World Heritage site was originally a cathedral, then became a mosque and most recently, a museum. Tap the link in our bio to read more about the change.

The stratigraphy of the Paleocene-Eocene German Rancho Formation of the Gualala Block is spectacular, especially when paired with an amazing sunset.
These turbidite deposits originated from the Western Mojave Portion of the Sierra Nevada Mountains that we’re formed ~100 m.y.a (see Sierras of the Sea posts from April). They were eroded from the rhyolite/granodiorite/tonalite that were the erupted lava (rhyolite) and solidified magma (granodiorite/tonalite) that formed the Sierra Nevada volcanic arc. These sediments deposited along submarine canyons and fans within the tectonically down-warped Gualala Basin formerly offshore of the coast of what is now Los Angeles some 65 million years ago. They deposited in a sequence alternating between sandstone and shale with some conglomerates, called flysch. Photo 1 and 2 show the dipping strata trending on the southwest limb of a synclinal fold. 3 and 4 feature closeups of the flysch beds from the right side of the first two frames (note the outlier bed of soft sediment deformation in the middle). Photo 5 is a closeup of flame structures from soft sediment deformation which happened as these deposits were compressed while saturated on the ocean floor, possibly settling from from seismic induced liquefaction as well. Photo 6 is what larger flame structures of soft sediment deformation look like from the top and after chemical and physical weathering from saltwater.
Hope you all have a safe and happy weekend.
The 75710 can carry a 450-tonne (440-long-ton; 500-short-ton) load. With an empty weight of 450 tonnes (440 long tons; 500 short tons). It is 20.6 m (67 ft 7 in) long, 8.16 m (26 ft 9 1⁄4 in) high, and 9.87 m (32 ft 4 5⁄8 in) wide.
Camadas do meio dobradas, camadas de baixo, planares. Que tipo de tectonismo formaria isto?🤔
Antecipando a resposta, não faria.
Na imagem, é possível observar dobras convolutas. Dobras convolutas são um tipo de estrutura atectônica. Estruturas como esta são causadas pela ação da gravidade sobre massas rochosas, através da compressão diferencial ou deslizamento de sedimentos inconsolidados.
Sua ocorrência é localizada, normalmente restrita a pequenas áreas, e são encontradas em escala de afloramentos.
