Granite Dome
Granite domes are domical hills composed of granite with bare rock exposed over most of the surface. Generally, domical features such as these are known as bornhardts. Bornhardts can form in any type of plutonic rock but are typically composed of granite and granitic gneiss. As granitic plutons cool kilometers below the Earth's surface, minerals in the rock crystallize under uniform confining pressure. Erosion brings the rock closer to Earth's surface and the pressure from above the rock decreases; as a result the rock fractures. These fractures are known as exfoliation joints, or sheet fractures, and form in onionlike patterns that are parallel to the land surface. These sheets of rock peel off the exposed surface and in certain conditions develop domical structures. Additional theories on the origin of granite domes involve scarp-retreat and tectonic uplift. Sheet fractures Sheet fractures are arcuate fractures defining slabs of rock that range from 0.5 to 10 meters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sugarloaf Mountain
Sugarloaf Mountain (, ) is a peak situated in Rio de Janeiro, Brazil, on a peninsula at the mouth of Guanabara Bay. Rising above the harbor, the peak is named for its resemblance to the traditional shape of concentrated refined loaf sugar. It is known worldwide for its cableway and panoramic views of the city and beyond. The mountain is one of several monolithic granite and quartz mountains that rise straight from the water's edge around Rio de Janeiro. Geologically, it is considered part of a family of steep-sided rock outcroppings known as bornhardts. The mountain is protected by the Sugarloaf Mountain and Urca Hill Natural Monument, created in 2006. This became part of a World Heritage Site declared by UNESCO in 2012. Origins of the name The name Sugarloaf was coined in the 16th century by the Portuguese during the heyday of sugarcane trade in Brazil due to sugar imports from the Portuguese conquest of Goa, according to historian Vieira Fazenda.

Radial Stress
Radial stress is stress toward or away from the central axis of a component. Pressure vessels The walls of pressure vessels generally undergo triaxial loading. For cylindrical pressure vessels, the normal loads on a wall element are longitudinal stress, circumferential (hoop) stress and radial stress. The radial stress for a thick-walled cylinder is equal and opposite to the gauge pressure Pressure measurement is the measurement of an applied force by a fluid (liquid or gas) on a surface. Pressure is typically measured in units of force per unit of surface area. Many techniques have been developed for the measurement of pressur ... on the inside surface, and zero on the outside surface. The circumferential stress and longitudinal stresses are usually much larger for pressure vessels, and so for thin-walled instances, radial stress is usually neglected. Formula The radial stress for a thick walled pipe at a point r from the central axis is given by : \sigma_r(r) = \frac+\ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dome (geology)
A dome is a feature in structural geology where a circular part of the Earth's surface has been pushed upward, tilting the pre-existing layers of earth away from the center. In technical terms, it consists of symmetrical anticlines that intersect each other at their respective wikt:apex, apices. Intact, domes are distinct, rounded, sphere, spherical-to-ellipsoidal-shaped protrusions on the Earth's surface. A slice parallel to Earth's surface of a dome features concentric rings of stratum, strata. If the top of a dome has been eroded flat, the resulting structure in Multiview_orthographic_projection#Plan, plan view appears as a Bullseye_(target), bullseye, with the youngest rock layers at the outside, and each ring growing progressively older moving inwards. These strata would have been horizontal at the time of Deposition_(geology), deposition, then later deformed by the Tectonic uplift, uplift associated with dome formation.
