Mother nature showing off again. Natural colours in this rock face, Freycinet Peninsular, Tasmania, Australia.
l wonder how many hundred of years is represented by the rings on these rocks for my daily picture
I'm always impressed with the varied rich colors of the rocks, boulders and mountains of Glacier Park. Pretty much any color can be found there. According to GNP their striking color comes from the small amount of iron in their composition. Red means oxygen was present when the rock formed, green means the atmosphere was lacking oxygen.
Here's an example taken at Many Glacier.
Thanks for taking a look!
Have a wonderful weekend!
Please no group invites!!! Thank you for your comments or faves!!!
Per favore no inviti a gruppi!!! Grazie per i vostri commenti o fav!!!
This one was taken coming up to a couple of months ago now. It's one of those shots that I kept on coming back to not knowing where to go with it, partly because there's no man made element in it for a change... but glad that I've finally got round to finishing it and hope I've done it justice.

I'm sure you're all getting a bit bored of my photos from last weekends visit to St Mary's but what can I say, I love it and had a blast! I've only got a couple more I promise.....
I can never resist a picture of the San Rafael Reef. Where there is a slot just big enough for the freeway to allow passage from one side to the other!
Check out those folds! Hubba hubba.

Thank you for all your kind comments and awards, much appreciated.
This picture is special to me. On Oct 28 artist-in-residence Jerry Ginsberg gave a presentation on light and composition in the Badlands. Jerry is an internationally acclaimed artist/photographer who is the only one to have photographed all the U.S. national parks in medium format. www.jerryginsberg.com/index
It was quite an experience and honor to spend time here on Door Trail with Jerry.
My friends Rachel Denton, paleontologist and Dennis Terry, geologist have spent their careers researching the Badlands. In their book "The White River Badlands", they describe the composition of the diverse soil types here on Door Trail and throughout the Badlands, including the sedimentology that encapsulated the rich plant and animal fossil beds.

another geology by the sea shot from me:))
hope you like it.)
thanks alot for stopping by leaving comments and faves:)) really appreciated.))
have a great week ahead everyone:))
Riverbanks eroded over the millennia. Another fabulous landscapes of Utah.

The granite rocks at Cape Point Nature Reserve. I found the history of the Cape Geology fascinating so here is an overview for those that may be interested.
The Peninsula Granite is a huge batholith that was intruded into the Malmesbury Group about 630 million years ago as molten rock and crystallised deep in the earth, but has since then been exposed by prolonged erosion. The characteristic spheroidal shapes of granite boulders are a result of preferential weathering along intersecting fractures and are well displayed around Llandudno and Simonstown. Close up, the granite is a coarse-grained rock consisting of large (2–5 cm) white or pink feldspar crystals, glassy brown quartz and flakes of black mica, and containing inclusions of dark Malmesbury hornfels.
The climate of this region was warmer and wetter in the Cretaceous. This led to severe chemical weathering of the granite to saprolite rich in kaolin clays, decomposed from the large visible crystals of potassium feldspar that are so conspicuous in the granite.
The contact zone where the Malmesbury Group was intruded by molten granite can be seen at Sea Point and was made famous by Charles Darwin during his voyage of scientific discovery on H.M.S. Beagle in 1844. Here, slivers of dark coloured Malmesbury rocks, altered by intense heat are intermingled and folded with the pale coloured intrusive granite to form a complex mixed rock. Large feldspar crystals occur in both the granite and dark hornfels layers. Though initially intruded at great depth, prolonged erosion eventually exposed the granite at the surface and it and what remains of the similarly eroded Malmesbury group now form a basement upon which younger sedimentary rocks of the Table Mountain Group were deposited.
Other large granite plutons of similar age are found in the Western Cape, but none of the others extend to the coastline in this area. The Stellenbosch pluton extends under the Helderberg and Hottentots Holland mountains. Cape Blue Rock, a dense Hornfels, was formed from the Malmesbury series rock by the Stellenbosch pluton, and was quarried as a building aggregate near Sir Lowry's Pass.The Blue Rock Quarry has been closed and is now flooded and used for water sports including diving and water skiing.
Appearance of the exposed Peninsula Granites
Almost all the exposed granite has been extensively weathered and is in the form of rounded corestones. The colour is generally pale to medium grey, and the surface is typically fairly rough, with clearly visible crystals, and no layered structure. As an intrusive rock, dip and strike do not apply, but the massive rock is cracked on jointing planes, which tend to be characteristic of the location, and weathering has accentuated these joints. The general direction and spacing of joints in some areas is fairly consistent over quite large areas, and the underwater landscape is often a continuation of the general trends above the surface, which can be useful for navigational purposes.
The amazing geology of Tyneham seaside - black rock on the left, chalk on the right far side and red coloured rocks to the the right. I heard that the tectonic plates collision pushed up the geological layers vertically in this area. Jurassic coast, Dorset.
A view from Kilt Rock Viewpoint on the Isle of Skye looking along the Trotternish peninsula, famous for the tagline “Theatre of Geology” it lies to the north of Portree and just South of Staffin. As you travel north from Portree the Geology does indeed consist of a landscape formed from landslides and erosion.
Le gole di Samariá (in greco: Σαμαριά) costituiscono un canyon lungo 16 km situato sul versante occidentale dei monti Lefka ed inciso profondamente dall'omonimo torrente, nell'isola di Creta, Grecia.
Si tratta probabilmente del più lungo canyon d'Europa dopo le gole del Verdon, in Francia.
Si trova al centro di un parco nazionale con due ingressi: uno alla foce del torrente Samarià raggiungibile dal vicino villaggio di Aghia Roumeli. L'altro con il nome di Xyloskala (letteralmente "la scala di legno") è in prossimità delle sue sorgenti, vicino al villaggio Omalos a 1250 m di altitudine
Lungo il percorso si possono ammirare delle strutture geologiche davvero notevoli, segno del passato tormentato dell'isola in epoche remote.

A strange geological formation protruding from the earth, in a vertical, straight line like a knife edge.
An dark capture on the edge of the loch near Ardtur with the layers of three mountain ridges in the horizon and some wonderful trees on the shoreline. Fences run all across the bay towards the sandy parts of the Loch Linnhe shore.

The noticeable line below the peaks is the Glarus Thrust. Geologists are quite fond of it… Wikipedia says: «The Glarus thrust (German: Glarner Hauptüberschiebung) is a major thrust fault in the Alps of eastern Switzerland. Along the thrust the Helvetic nappes were thrusted more than 100 km to the north over the external Aarmassif and Infrahelvetic complex. The thrust forms the contact between older (Helvetic) Permo-Triassic rock layers of the Verrucano group and younger (external) Jurassic and Cretaceous limestones and Paleogene flysch and molasse.
The Glarus thrust crops out over a relatively large area in the cantons Glarus, St. Gallen and Graubünden, due to its horizontal orientation and the high local relief. Famous outcrops include those at Lochsite near Glarus (the town) and in a mountain cliff called Tschingelhörner between Elm and Flims (in the same cliff is a natural hole called the Martinsloch).»
Amazing rock formation at Lulworth cove , there is so much erosion at this beautiful location , not sure how long its all going to last :(
