𝗔𝗿𝗼𝘂𝗻𝗱 𝟱𝟬 to 𝟲𝟬 𝗺𝗶𝗹𝗹𝗶𝗼𝗻 𝘆𝗲𝗮𝗿𝘀 𝗮𝗴𝗼, during the 𝗣𝗮𝗹𝗲𝗼𝗰𝗲𝗻𝗲 𝗘𝗽𝗼𝗰𝗵, Antrim was subject to 𝗶𝗻𝘁𝗲𝗻𝘀𝗲 𝘃𝗼𝗹𝗰𝗮𝗻𝗶𝗰 𝗮𝗰𝘁𝗶𝘃𝗶𝘁𝘆, when highly fluid 𝗺𝗼𝗹𝘁𝗲𝗻 𝗯𝗮𝘀𝗮𝗹𝘁 𝗶𝗻𝘁𝗿𝘂𝗱𝗲𝗱 through 𝗰𝗵𝗮𝗹𝗸 𝗯𝗲𝗱𝘀 to form an 𝗲𝘅𝘁𝗲𝗻𝘀𝗶𝘃𝗲 𝘃𝗼𝗹𝗰𝗮𝗻𝗶𝗰 𝗽𝗹𝗮𝘁𝗲𝗮𝘂. As the lava 𝗰𝗼𝗼𝗹𝗲𝗱, 𝗰𝗼𝗻𝘁𝗿𝗮𝗰𝘁𝗶𝗼𝗻 occurred. 𝗛𝗼𝗿𝗶𝘇𝗼𝗻𝘁𝗮𝗹 𝗰𝗼𝗻𝘁𝗿𝗮𝗰𝘁𝗶𝗼𝗻 𝗳𝗿𝗮𝗰𝘁𝘂𝗿𝗲𝗱 in a similar way to 𝗱𝗿𝘆𝗶𝗻𝗴 𝗺𝘂𝗱, with the cracks propagating down as the mass cooled, leaving 𝗽𝗶𝗹𝗹𝗮𝗿-𝗹𝗶𝗸𝗲 𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲𝘀.

The picture showing a pillow basalt from maradihalli village. It is around ~2600 ma and formed in the marine environment as evidenced by spilitization at some places. Even after million ages, the pillows are undeformed and intact hence this site is recognized as the National Geological Heritage.

Here you can appreciate the chilled margin, v/y junctions, piped vesicles, rind and radial cracks etc.

A pillow basalt forms when basaltic magma get erupted into aqueous environment, thus they cooled as pillowed, bulbous shaped bodies.

A layer of anhydrite in a background of rock salt (z3AM). The anhydrite layer (z3AMah), being stiffer, has been boudinaged, the necks of the boudins are filled with secondary halite. The bed was then folded, the necks acting as points where the fold axis formed. Taken in the Morsleben salt mine and depository.

Granite domes or bornhardts are abundantly developed inthat area of south-western Western Australia popularlyknown as the Wheat Belt.

Wave Rock near Hyden Western Australia
Formed more than 2700 million years ago, Wave Rock is 14 metres high, and 110 metres long. The granite cliff resembling a wave about to break is on the northern face of a large erosional remnant called Hyden Rock. This curved cliff face has been rounded by weathering and water erosion, undercutting its base and leaving a rounded overhang. It was formed by water dissolving and re-depositing chemicals in the granite as it runs down the cliff face.

Granite domes or bornhardts are abundantly developed inthat area of southwestern Western Australia popularlyknown as the Wheat Belt. The Wheat Belt region is well known for one superb example of a flared slope, in Wave Rock (Figure lla), on Hyden Rock, though many other fine examples are exposed elsewhere on Hyden Rock and and other residuals. Flared slopes are well developedon similar granitic bornhardts on northwestern EyrePeninsula. Though their development is more complex thanwas at first thought, there is no doubt that they were initiated beneath the land surface as a result of subsurfaceweathering in the scarp-foot zone, and that the uppershoulder of the concavity marks a former hill-plain junction. Such flared slopes and associated caverns, or tafoni, and breaks of slope occur not only around the bases of the hills but also in various zones onthe hill slopes. The result is inselbergs that are stepped,with platforms or treads alternating with flared slopes or
steps. They imply exposure of the residuals not in a single phase of erosion of the surrounding plains, but rather episodically, with several alternations of weathering and erosion in evidence."

The geology of Armenia was shaped by geological upheaval pushed up the Earth's crust to form the Armenian Plateau 25 million years ago. This created the complex topography of Armenia.

The Garni Gorge is situated 23 km east of Yerevan, Armenia, just below the village of the same name. On a promontory above the gorge the first-century AD Temple of Garni may be seen. Along the sides of the gorge are cliff walls of well-preserved basalt columns, carved out by the Goght River. This portion of the Garni Gorge is typically referred to as the "Symphony of the Stones".

The origin of columnar jointing is still uncertain, although it is usually explained by analogy with mud-cracks resulting from shrinkage at the surface of dried-up mud. The polygonal cracks in basalts are presumed to be due to contraction during cooling. It is assumed that the contraction acts towards a series of equally spaced cooling centres. A tension crack is supposed to form between two centres and since each centre is surroundedby many others, this leads to a multi-sided polygonal crack system that splits the rock intoroughly uniform polygonal blocks. As cooling proceeds to the interior, cracks are supposedto propagate inward at right angles to the cooling surface resulting in columnar structure."

Flysch is a sedimentary rock formation that consists of alternating layers of shale, mudstone, sandstone, calcarenite, or conglomerate. It is formed in deep water environments, often in tectonically active orogenic belts.
