Ocean floor material is largely composed of basalt, which is relatively dense ; when it collides with the lighter granite rocks of Central America, the ocean floor is forced down under the land mass, creating the deep Middle America Trench that lies off the coast of El Salvador.

Joseph Dixon, an inventor and entrepreneur involved with the Tantiusques granite mine in Sturbridge, Massachusetts, developed a means to mass produce pencils.

This may be seen in many granite intrusions where later aplite veins form a late-stage stockwork through earlier phases of the granite mass.

The main feature of the park, besides the many disappearances, is the mass of granite boulders, some the size of houses.

This large mass of igneous rock is the largest granite outcropping in North America.

Most of the highest ground is formed by the masses of granite which have been intruded into the Ordovician and Silurian rocks ; the Criffel mass lies about Dalbeattie and Bengairn, another mass extends east and west between the Cairnsmore of Fleet and Loch Ken, another lies northwest and southeast between Loch Doon and Loch Dee and a small mass forms the Cairnsmore of Carsphairn.

The uplifting and increased erosion exposed granitic rocks in the area to surface pressures, resulting in exfoliation ( responsible for the rounded shape of the many granite domes in the park ) and mass wasting following the numerous fracture joint planes ( cracks ; especially vertical ones ) in the now solidified plutons.

Of these, the granite mass of Spango Water, northeast of Kirkconnel, is an excellent example.

Endoskarns, including greisens, form within the granite mass itself, usually late in the intrusive emplacement and consist of cross-cutting stockworks, cooling joints and around the margins and uppermost sections of the granite itself.

Exoskarns are formed when fluids left over from the crystallisation of the granite are ejected from the mass at the waning stages of emplacement.

The edict is inscribed high up on a large, domed mass of black granite.

The intrusive granite of the rock mass, or pluton, was exposed by extensive erosion of the surrounding sedimentary rock, primarily the Cretaceous Edwards limestone, which is exposed a few miles to the south of Enchanted Rock.

Metasomatic albite + hornblende + tourmaline alteration of metamorphosed granite, Stone Mountain, Atlanta In the igneous environment, metasomatism creates skarns, greisen, and may affect hornfels in the contact metamorphic aureole adjacent to an intrusive rock mass.

These rocks were intruded by a mass of granite 1400 Ma ( million years ago ) and later uplifted and exposed to nearly 500 million years of erosion.

A mass of granite now in the Panamint Mountains intruded this complex 1400 mya.

The granite that forms them was originally a mass of magma that had worked its way up into the surrounding sedimentary rocks during the Devonian period, when the land surface in Victoria was several kilometres higher than today.

According to the fall 1882 edition of La Nature, its dimensions before being cut were 7 × 14 × 9 m. Based on the density of granite, its mass was determined to be around 1500 tonnes.

The mass grave is now marked by a granite monument.

Edward Robinson visited the site in the mid-19th century, describing the " remains of the ancient church ," lying just above the well to the southwest as a " shapeless mass of ruins, among which are seen fragments of gray, granite columns, still retaining their ancient polish.

This granite was crystallised as a large mass from magma 400 million years ago miles from the Earth's surface and was gradually eroded and uplifted to its current position.

The figure and the base are made of algonite stone ( a poured mass ) of which Missouri granite is used as the main aggregate.

Scientists say it is the last spewings of a great glacier, but one rather feels that only a malevolent giant could have piled up those crouching monsters of granite which still seem to preserve a sort of suspended, ominous life in them.

The memorial is a pentagonal granite marker high.

More recently, high-quality crystals have been obtained from Pike's Peak, Colorado, where it is found associated with smoky quartz, orthoclase, and albite in a coarse granite or pegmatite.

Geologic occurrence is in granite pegmatites, high-temperature tin veins, and greisens.

Balmoral Castle is built from granite quarried at Invergelder on the estate, and comprises two main blocks, each arranged around a courtyard.

The Museum is faced with Portland stone, but the perimeter walls and other parts of the building were built using Haytor granite from Dartmoor in South Devon, transported via the unique Haytor Granite Tramway.

Bodmin Moor () is a granite moorland in northeastern Cornwall, England, United Kingdom.

Bodmin Moor is one of five granite plutons in Cornwall that make up part of the Cornubian batholith ( see also Geology of Cornwall ).

The aggregate is generally a coarse gravel or crushed rocks such as limestone, or granite, along with a fine aggregate such as sand.

To the northwest is the Yade Massif, a granite plateau with an altitude of.

The weathering of silicate rocks like granite, on the other hand, is a net CO < sub > 2 </ sub > sink because it produces abundant Ca < sup > 2 +</ sup > but very little CO < sub > 2 </ sub >.

Such rocks as granite, which have cooled very slowly and under great pressures, have completely crystallized ; but many kinds of lava were poured out at the surface and cooled very rapidly, and in this latter group a small amount of amorphous or glassy matter is common.

In the dry season, it has shallows, and is obstructed by sandbanks, a few rapids and granite rocks.

Childe's Tomb is a granite cross on Dartmoor, Devon, England.

Childe's Tomb is a reconstructed granite cross on the south-east edge of Foxtor Mires, about 500 metres north of Fox Tor on Dartmoor, Devon, England at.

Today the cross, which is a replacement, is about 3 feet 4 inches ( 1 m ) tall and 1 foot 8 inches ( 0. 5 m ) across at the crosspiece, and it has its base in a socket stone which rests on a pedestal of granite blocks that raises the total height of the cross to 7 ft ( 2. 1 m ).

The whole is surrounded by a circle of granite stones set on their edge which once surrounded the cairn — the rocks of which are now scattered around — that was originally built over a large kistvaen that still exists beneath the pedestal.

The granite peak is located in the Tijuca Forest, a national park.

The peak of Corcovado is a big granite dome, which describes a generally vertical rocky formation.

The four pillars set up by Cão on his two voyages have all been discovered in situ, and the inscriptions on two of them from Cape Santa Maria and Cape Cross, dated 1482 and 1485 respectively, are still to be read and have been printed ; the Cape Cross padrão is now at Kiel ( replaced on the spot by a granite facsimile ); those from the Congo estuary and the more southerly Monte Negro are in the Museum of the Lisbon Geographical Society.

A solid base is a must for any successful course, and where early courses had plain dirt pads, modern courses use concrete, or more cost effective materials such as mulch, decomposed granite, or other natural materials.

Its intricately carved wooden fascia is supported on granite columns.
