Some beautiful tectonic activity - folded limestone and shales!

Divergent boundary, also known as a constructive boundary or an extensional boundary, is a linear geologic feature that exists between two tectonic plates that are moving away from each other.

From lightest (oldest) to darkest (youngest) tectonic plates. No, I do not differentiate the sea and land plates, hence the numbers as markings (also easier ID without colors). The third one is a bit darker than the second one IRL.

page 553 - I breathe again and the mountains have changed.

Imperceptibly but definitely.

Time loses meaning in the darkness down here. But still my brain spins and my heart races and it's good to breathe deeply, to slow down and to attempt a better grasp on things.

The air is murky, but there is no food and water only in drips, so a deep breath is the only thing available to fill me up.

"The Swiss Tectonic Arena Sardona in the north-eastern part of the country covers a mountainous area of 32,850 ha which features seven peaks that rise above 3,000 m. The area displays an exceptional example of mountain building through continental collision and features excellent geological sections through tectonic thrust, i.e. the process whereby older, deeper rocks are carried onto younger, shallower rocks. The site is distinguished by the clear three-dimensional exposure of the structures and processes that characterize this phenomenon and has been a key site for the geological sciences since the 18th century. The Glarus Alps are glaciated mountains rising dramatically above narrow river valleys and are the site of the largest post-glacial landslide in the Central Alpine region." - UNESCO

The Space, Astronomy & Science Podcast. SpaceTime Series 27 Episode 41 *The Scandinavian Connection: Born from Greenland's Ancient Crust In a groundbreaking geological study, scientists have traced the oldest Scandinavian bedrock back to its origins in Greenland, revealing a continental connection dating back 3.75 billion years. Published in the journal Geology, this research uncovers a hidden chapter of Earth's crust beneath Denmark and Scandinavia, suggesting a tectonic detachment from Greenland that predates previous estimates by a quarter of a billion years. The discovery, locked within zircon minerals, not only reshapes our understanding of continental drift but also underscores Earth's uniqueness in the solar system as a cradle for life. *Blue Origin's Orbital Reef: A Leap Towards Commercial Space Habitats Blue Origin, in collaboration with Sierra Space, has achieved a significant milestone in the development of the Orbital Reef commercial space station. Under NASA's watchful eye, the project has successfully tested key life support systems essential for sustaining human presence in orbit. With a potential operational date as early as 2027, Orbital Reef aims to provide a voluminous habitat for ten occupants, marking a new era in space exploration and research as the International Space Station approaches retirement. *Space's Role in Climate Change Monitoring Intensifies The World Meteorological Organization's latest report delivers a stark reality check, with 2023 witnessing unprecedented levels of greenhouse gases, rising seas, and melting ice. In response, the fleet of Copernicus Sentinel satellites operated by the European Union plays an increasingly vital role in monitoring our changing planet. These eyes in the sky offer critical data, from sea ice dynamics to deforestation, aiding policymakers in crafting strategies to combat the escalating climate crisis. *Dragon's Bounty: A Resupply Mission Brimming with Scientific Promise SpaceX's CRS-30 mission, aboard the upgraded Dragon spacecraft, has successfully docked with the International Space Station, delivering over 2.7 tonnes of vital supplies and novel experiments. This cache of scientific endeavors includes a joint CSIRO-Boeing 3D mapping project, the Burst Cube satellite for studying cosmic gamma-ray bursts, and the GEARS initiative for identifying antibiotic-resistant microbes in space. With over 250 experiments in progress, the orbiting laboratory continues to be a beacon of discovery and innovation.

Surigao del Sur Experiences Magnitude 5.7 Quake

A magnitude 5.7 tremor was felt in some parts of Surigao del Sur early Wednesday evening according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS). The quake which struck at 8:32 p.m. was tectonic in origin as per PHIVOLCS and that it was located some 30 kilometers northeast of Hinatuan in the said province. It had a depth of focus of 26 kilometers and was an aftershock of…

Scientists Discover Ghost of Ancient Mega-Plate That Disappeared 20 Million Years Ago

A Long-lost Tectonic Plate Dubbed “Pontus” that was a quarter of the size of the Pacific Ocean was discovered by chance by Scientists in Borneo

A long-lost tectonic plate that once underpinned what is today the South China Sea has been rediscovered 20 million years after disappearing.

The plate is known only from a few rock fragments from the mountains of Borneo and the ghostly remnants of its huge slab detected deep in Earth's mantle. It was once a quarter of the size of the Pacific Ocean. Scientists have dubbed it the "Pontus plate" because at the time of its existence, it sat under an ocean known as the Pontus Ocean.

"It's surprising to find remnants of a plate that we just didn't know about at all," Suzanna van de Lagemaat, a doctoral candidate at Utrecht University in the Netherlands, told Live Science.

Van de Lagemaat and her colleagues were initially studying the Pacific plate under the Pacific Ocean. Tectonic plates constantly move against one another, and the crust in oceanic plates is more dense than continental plates, so oceanic plates get pushed under continental plates in a process called subduction and disappear. Sometimes, however, rocks from a lost plate get incorporated into mountain-building events. These remnants can point to the location and formation of ancient plates.

The researchers were attempting to find remnants of one of these ancient lost plates, known as the Phoenix plate, while doing fieldwork in Borneo. Scientists can look at the magnetic properties of rocks to learn when and where they formed, van de Lagemaat said; the magnetic field that surrounds Earth gets "locked in" to rocks when they form, and that magnetic field varies by latitude.

But the researchers found something strange when they analyzed the rock they'd collected in Borneo.

"This latitude didn't fit with the latitude we got from the other plates that we already knew about," van de Lagemaat said.

To unravel the mystery, she used computer models to investigate the region's geology over the last 160 million years. The plate reconstruction showed a hiccup between what is now South China and Borneo — an ocean once thought to be underpinned by another ancient plate called the Izanagi plate actually wasn't on that plate. Instead, the Borneo rocks fitted into that mystery gap.

The researchers discovered the spot was actually occupied by a never-before-known plate, which van de Lagemaat and her team named the Pontus plate.

The reconstruction, published Sept. 29 in the journal Gondwana Research, shows that the Pontus plate formed at least 160 million years ago but was probably far older. (The rock samples collected in Borneo date back 135 million years.) It was once enormous but shrank steadily over its lifespan, finally getting pushed under the Australian plate to the south and China to the north, disappearing 20 million years ago.

Decade-old research from the same lab also showed a hint of the Pontus plate. That research looked at imaging of Earth's middle layer, the mantle, where the subducted crust ends up. It showed a huge slab of crust of unknown origin, but scientists at the time had no way to determine where it came from, van de Lagemaat said. Now, it's clear that this crust is what's left of the Pontus plate.

— Borneo, a giant, rugged island in Southeast Asia’s Malay Archipelago, is shared by the Malaysian states of Sabah and Sarawak, Indonesian Kalimantan and the tiny nation of Brunei. It’s known for its beaches and ancient, biodiverse rainforest, home to wildlife including orangutans and clouded leopards. In Sabah is 4,095m-tall Mount Kinabalu, the island’s highest peak, and, offshore, the famed dive site Sipadan Island.
