Dune 45.

At over 80 m tall Dune 45 is a huge star dune in the Soussevlei area of the Namib Desert. The mature to supermature quartz sand that makes up this dune is some 5 million years old and sourced from the Kalahari Desert by the Orange River. 
Star dunes are radially symetrical with three or more slipfaces (arms) that radiate from the central pyramidal mound. Formed due to multidirectional winds these dunes grow up not out.

Layer cake.

One of the earliest observations that promoted the modern view of geology and deep time was that sediments are deposited in originally flat layers that get stacked ontop of each other. Here in the muds and sands of the fluvial Kayenta formation we see this borne out in the many layers of wet season sands and darker coloured dry season muds that depostied during the Lower Jurassic some 190 million years ago. (FOV: 10 cm)

Vasquez rocks: geology, crime, movies.

These impressive strata are largely coarse (gravels and pebble) sandy conglomerates and breccias deposited due to active faults driving rapid uplift and erosion of the San Gabriel Mountains. 25 million years ago during the Oligocene the Pacific-North American collision zone uplifted the area and erosion coupled with volcabism drove rapid deposistion of alluvial fans into a subsiding rift valley. These alluvial sediments were lithified during the Miocene and reexposed in the Cenozoic due to fault activity along the San Andreas fault. Now exhibiting a high degree of tilt exaccerbated by the hogback ridges these rocks are tedtament to the dynamic tectonics of the SW USA.

The formations name of Vasquez rocks is attributed to one of California's most notorious bandits in 1873-74; Tiburcio Vásquez. This bandit hid from the law in these craggy rocks.

More recently the location has been used in almost countless film and television projects. Most notably in an episode of Star Trek where Captain Kirk fights the Alien Gorn.

This isn't a fossil honeycomb!

Paleodictyon imperfectum is a trace fossil (preserved interaction of organism with soft sediment) found in the geoloogical record of marine settings from the Early Cambrian through to the modern. Despite a lot of modelling work the fossil has been interpreted as either 1) iterative modular growth of an organism, 2) burrows, 3) actually a body fossil or 4) an abiotically produced structure. A fifth hypothesis suggests that these are farming traces. An organism may line its tunnel walls with mucus allowing algae and fungi to grow, providing a food source. These Paleodictyon are from the Late Miocene sedimentary assemblages of marls and turbidites in the Tabernas Basin of Almería, Spain.

Did we land on Mars?

You might be mistaken for thinking you were looking at a picture sent back by the Mars Rover but this is still Earth. Fluvial (river) processes are responsible for transporting and depositing sediment in these classical cross-bedded patterns capped with salts and clays. At less than 10 cm high these cross-beds are like miniature versions of the behemoth sand dunes up to 400 m high that encircle the Deadvlei. Deadvlei was formed when the Tsauchab river flooded and created sediment (clay) and mineral (salt) laden pools. When the climate moved from wet to arid, water evaporated and sand dunes migrated in blocking off the river from recharging the pools.

Better call a dentist.

Mammoth cave in the Margaret River region of SW Western Australia is a worldclass palaeontological site. Pleistocene remains of many marsupial megafauna have been uncovered here, but it is the Jaw bone of a Zygomaturus that takes the spotlight. Going extinct ~45,000 years ago the wombat like animal weighed in at a huge 500 kg and stood 1.5 m tall. The animal was likely a swamp grazer, gathering reeds and hedges with its forward facing lower incisors.

What are your favourite natural pallettes?

These spectacular colours are formed through weathering processes affecting the Broome Sandstone that crops out here. Different oxidation and hydration states of iron cause the differing hues of red, yellow and orange that are typical of arid to semi-arid settings. The sandstones were deposited during the Creataceous around 130 Ma in shallow marine settings. At low tide worldclass fossilised therapod dinosaur trackways are visible about 30 m below the cliffs.

Which way up? Lovely sedimentological evidence indicating younging direction in the Portscatho Formation at Mawnan in south Cornwall. The sharp contact with the mudstone is overlain my normally graded coarse sandstone. And to really confirm things, a flame of mudstone protrudes in to the sandstone. These load structures occur during sedimentation when the denser sand is deposited which can push the unconsolidated mud upwards. The Portscatho Formation is late Devonian and is made up of submarine turbidites, forming during syn-convergence sedimentation. Field of view is about 12 cm.

Neoproteroziic cross bedded sandstones and pebble to boulder, poorly sorted, subangular conglomerates of the Jacob Quartzite, Sisters Beach, northwestern Tasmania.  Detrital zircon dating indicates a maximum age of 1.010 billion years; minimum age ~750 million years. Some vague imbrication helps determine flow direction.

Speleothems of Mawjymbuin Cave, Shillong , India

Speleothems sometimes referred to as formations or decorations, are cave features formed by the deposition of minerals. The word speleothem is derived from the Greek words spelaion meaning "cave" and thema meaning "deposit". The speleothems with which most people are familiar are stalactites and stalagmites. Stalactites grow down from the cave ceiling, while stalagmites grow up from the cave floor. It’s easy to remember which is which: Stalactites have a "T" for top and stalagmites have a "G" for ground.

A mini alluvial fan or fluvial distributary system developed during falling tide where a freshwater stream meets a beach in Cornwall, UK. The apex is an incised channel which is eroding into the beach. Downstream the fan becomes unconfined with increasing sinuosity and then terminal unconfined lobes. The water here infiltrates into the sand as he flow spread out and the rate of infiltration exceeds the flow discharge. #alluvialfan #sand #fluvial #sedimentology

Happy New Year from Doctor Ripple! Here's some relaxing swash on a beach in Cornwall, uk. Fast shallow currents caused by breaking waves rush up and down (backwash) the foreshore. As these flows are fast and shallow, they are in the upper flow regime and a plane bed forms. #sedimentology #sedimentarystructures #beachprocesses #beaches #planebed

Coarse-grained layers of cretaceous saxon sandstone in fine-grained sandstone. The bigger the particles/grains in a sediments are, the greater the transport energy must have been, in order to transport these particles. This fact leads to the conclusion that the "normal" flow regime must have been relatively low, which led to the sedimentation of fine grains, mainly composed of quartz. However there must have been events, where the energy of the flow regime must have been increased, so that coarse particles could be transported. This can be  triggered by different causes: One of them could be a regression of the sea, another could be that for a brief period of time a river ran through the area, that lead to an increase in the flow regime. I do not know the reason but I was able to track the horizon several hundred meters. This leads me to the thesis, that the sea level must have been lowered and raised for at least two times.

Grobsandsteinhorizonte in Feinsandstein in der Sächsischen Schweiz. Je gröber die Partikel, desto größer muss die Transportenergie gewesen sein. Möglicherweise handelt es sich hierbei um eine Regression des Meeresspiegels.

What would you do if you come here??? Understand Puente del Inca Formation, mountain building or swim on thermal waters?

_"El Puente del Inca" was formed as an ice bridge, probably during the last maximum glacial; the ice was covered by avalanches debris from the adjacent slope; then during thawing the bridge was supported by the mud matrix of the conglomerates, which subsequently were cemented by the minerals of the hot-thermal springs.

Understand Puente del Inca Formation, mountain building or swim on thermal waters? _"El Puente del Inca" was formed as an ice bridge, probably during the last maximum glacial; the ice was covered by avalanches debris from the adjacent slope; then during thawing the bridge was supported by the mud matrix of the conglomerates, which subsequently were cemented by the minerals of the hot-thermal springs.

Laminated quartz sandstone. Yes! Geology's everywhere! When in need of cool bedrock, even in a place like S Florida where there hardly is any, you can always look at building stones!

Fossilized Crinoid at the Museum of Natural History, Washington DC.
Crinoid fossils are mostly found as fragments. Where one finds a crinoid as beautifully preserved as the one shown, it indicates very rapid burial of the live creature.

Flute Cast in sandstone. Flute casts are scours dug into soft, fine sediment which typically get filled by an overlying bed (hence the name cast). Measuring the long axis of the flute cast gives the direction of flow, with the tapered end pointing toward the flow and the steep end up current. The concavity of the flute cast also points stratigraphically up.
