There are three types of basalt -- a'a, pahoehoe, and transitional. Pahoehoe (pronounced "pa-hoy'-hoy") is smooth, and a'a (pronounced "ah'-ah") looks like cinders. Transitional is basalt that displays characteristics of the other two types together. The difference is not chemical, but depends on the temperature of the lava when it began to cool.

Detail from a large drum-shaped building on the waterfront in Akureyri on the north coast of Iceland. The geometric basalt columns that are a common feature of Icelandic geology have been sliced and affixed to the exterior, with attention to spacing so that whole columns frame all openings. The effect is quite striking - one could easily picture a whole town built this way - but the earthquake-conscious Californian in me worries a lot about how the stone is attached.

In these basalt exposures at Arnastapi, western Iceland, the characteristic jointing of this rock type is still evident, albeit in a very contorted display. The advanced rounding of the basalt blocks forming the boulder beach is testimony to the high energy of the local wave climate.
Located at Reynisfjara on the south coast of Iceland are the basalt pillars Reynisdrangar that rise from the sea. Legend has it that these are trolls that turned into stone when day broke. On the left hand side are basalt columns that have hexagonal shape. Surprisingly, this was my first visit to Reynisfjara which is incomprehensible to me since it is easily accessible and close to the main highway along the south coast. Lee ND 0.6 soft + Big Stopper.
Reynisdrangar are basalt sea stacks located just off the coast of southern Iceland near the town of Vik i Myrdal. Reynisfjara beach is close by and is famous for its black sand and also
infamous for its sneaker waves that roll in from the North Atlantic.
Cooling joints in the basalt are visible across the Yellowstone River at the Calcite Springs Overlook. The basalt sits on top of Pliocene/Pleistocene gravels on the river’s east side.
They even call the place "Basalt"! I was stunned. Coming from eastern Australia, I was familiar with basalt in many places, but was totally ignorant of there being basalt on the coast of South-West of WA!
A "Basalt Wall" and basalt outcrops evident on the beach below took me totally by surprise. Western Australia is an ancient, very ancient, block of the earth's crust, so why is there basalt here? I pondered this for about 15 minutes then it dawned! This is evidence of the lava that issued as the ancient continents broke up, for this is where India Plate separated from the Australian continent, and as it did (just as in East Africa today) lava flowed to the surface and down a rift valley existing at the time!
I understand that this basalt has been traced for 150 kms using aeromagnetic recording south to Black Point and then out to sea, and that in places it is over 200m thick!
When did India and Australia separate? About 130 million years ago.
And where is this? At Bunbury on the edge of the Australia Plate.

When staying at Long Beach, Washington recently, there was something marked on Google maps as "Basalt Monolith" - it is a stone with some quotes about sturgeons on it and in the background, a statue of an 'explorer' and a big sturgeon. (Still working on prints of that...)
Basalt sea stacks called Reynisdrangar, located under the Reynisfjall mountain, close to Vik i Myrdal in southern Iceland. Here's on of them on a cold November evening.
The legend was that there were three trolls who were pulling a three masted ship to the shore unsuccessfully, but they were caught by the sunlight at dawn and turned them into needles of rock.
Looks best on black.
Comments as always appreciated, but please no flashy award codes.

Still sat on a bunch of images in the archives from leading this years Icelandic Adventure for Welshot Imaging, this one though, is one of my favourites. A last grab as I made my way back to our transport, thinking I would have to spend the next 30mins running all over the headland dragging people away from the views... to discover they were already there drinking vodka waiting ;-)

The flat-topped basalt mountains of Disko Island around Qeqertarsuaq, Greenland, were created by volcanic activity tens of millions of years ago. Disko is Greenland's second largest island after the main island.

basalt of volcanic origin has been weathered - the different colours are due to to different minerals

Fingal is located in the Tweed Region just south of the Tweed River. Fingal Head boasts some of the most spectacular examples of columnar jointing to be found. The columnar basalt lava flow at Fingal Head extends underwater to Cook Island. The jointing is caused by contraction, as lava cools from the outside toward the centre, shrinkage cracks develop, usually forming hexagonal patterns (the shape of the columns is attributed to tensional stress). These columns are vertical because the lava cools from top to bottom when the flow of lava is horizontal.

Vík, Iceland. Photo collaboration with Nick.
When we arrived at Reynisfjara ( a black sand beach) near the village of Vík í Mýrdal in southern Iceland, my attention was grabbed by spectacular columnar basalt that makes up the cliff where Reynisfjal, a mountain ridge, meets the sea. Nestled in among the columns at the base of the cliffare some beautiful basalt caves. The deepest and most famous is Hálsanefshellir. In this view a shallow cave is to the left and the beach to the right. A sheer cliff of basalt columns, shown in the middle of the photo, welcomes visitors this cave in an alcove. It is not Hálsanefshellir. I never found out its name so I call it "Not Hálsanefshellir" . It has a wider and taller entrance than its famous neighbor.
An old volcano (180 million years) with giant boulders of volcanic basalt.Interesting to see how the shape is re-inforce by the moss.
Dense orographic clouds shroud the Ko’olau mountains at the He’eia Stream headland. With a ridgeline elevation of 1,600 feet in this area, these intermittent waterfalls plunge hundreds of feet dissecting and carving the basalt of the windward pali. As it always does, water will eventually win, and the island will erode to a coral atoll.
From lofty orographic peaks,
A waterfall through rainforest leaps.
In tumbling, silvery, glistening mirth,
It recycles back to its ocean birth. -RW

The bedrock here seem to reflect two distinct volcanic episodes.

... panorama ... the chalk cliffs of Larrybane contrast with the basalt stack and Sheep Island. A fault line runs close to the shore. These are the same basalts as those of the Giant's Causeway further along the coast ...

Kalfshamarsvik Lighthouse in Iceland is set on beautiful basalt rock columns that are very visible in the summer. In the winter they’re less visible but with just the right amount of snow they form amazing foreground contrast. This photo was taken at the beginning of a cold and windy night waiting for some weather to dissipate in the hopes of catching some aurora activity.
Since I haven’t posted for a long time I will try to catch up with contacts in the days to come :-)
