Earthquakes make gold veins in an instant | #Geology #GeologyPage #Earthquake #Gold

Scientists have long known that veins of gold are formed by mineral deposition from hot fluids flowing through cracks deep in Earth’s crust. But a study published today in Nature Geoscience1 has found that the process can occur almost instantaneously — possibly within a few tenths of a second.

How Do Crystals Form & Grow? | #Geology #GeologyPage #Crystals

A crystal or crystalline solid is a solid material whose constituents, such as atoms, molecules or ions, are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations.

Mudpot | #Geology #GeologyPage #Mudpot

A Mudpot "or Mud Pool" is a sort of acidic hot spring, or fumarole, with limited water. It usually takes the form of a pool of bubbling mud. The acid and microorganisms decompose surrounding rock into clay and mud.

7 Strong Men of Russia

Standing majestically tall are mysterious seven giant rock formations in hard to reach Northern Ural area of Komi Republic. More info in the Link

From the link below: A geological fold occurs when one or a stack of originally flat and planar surfaces, such as sedimentary strata, are bent or curved as a result of permanent deformation. Synsedimentary folds are those due to slumping of sedimentary material before it is lithified. Folds in rocks vary in size from microscopic crinkles to mountain-sized folds. They occur singly as isolated folds and in extensive fold trains of different sizes, on a variety of scales.

Folds form under varied conditions of stress, hydrostatic pressure, pore pressure, and temperature gradient, as evidenced by their presence in soft sediments, the full spectrum of metamorphic rocks, and even as primary flow structures in some igneous rocks. A set of folds distributed on a regional scale constitutes a fold belt, a common feature of orogenic zones. Folds are commonly formed by shortening of existing layers, but may also be formed as a result of displacement on a non-planar fault (fault bend fold), at the tip of a propagating fault (fault propagation fold), by differential compaction or due to the effects of a high-level igneous intrusion e.g. above a laccolith.

Ellison's Cave, Georgia | #Geology #GeologyPage #Cave #UnitedStates

Ellison's Cave is a pit cave located in Walker County, on Pigeon Mountain in the Appalachian Plateaus of Northwest Georgia. It is the 12th deepest cave in the United States and features the deepest, unobstructed underground pitch in the continental US named Fantastic Pit. The cave is over 12 miles long and extends 1063 feet vertically.

A history of snowfall on Greenland, hidden in ancient leaf waxes | #Geology #GeologyPage #Greenland

The history of Greenland's snowfall is chronicled in an unlikely place: the remains of aquatic plants that died long ago, collecting at the bottom of lakes in horizontal layers that document the passing years.

Using this ancient record, scientists are attempting to reconstruct how Arctic precipitation fluctuated over the past several millennia, potentially influencing the size of the Greenland Ice Sheet as the Earth warmed and cooled.

Map of flow within the Earth's mantle finds the surface moving up and down 'like a yo-yo' | #Geology #GeologyPage #Earth #Mantle

Researchers have compiled the first global set of observations of the movement of the Earth's mantle, the 3000-kilometre-thick layer of hot silicate rocks between the crust and the core, and have found that it looks very different to predictions made by geologists over the past 30 years.

Dallol Volcano | #Geology #GeologyPage

Dallol is a volcanic explosion crater (or maar) in the Danakil Depression, northeast of the Erta Ale Range in Ethiopia. It has been formed by the intrusion of basaltic magma in Miocene salt deposits and subsequent hydrothermal activity. Phreatic eruptions took place here in 1926, forming Dallol Volcano, numerous other eruption craters dot the salt flats nearby.

Split Apple Rock "Tokangawhā" | #Geology #GeologyPage #Tokangawhā #NewZealand

Split Apple Rock "Tokangawhā" is a geological rock formation in The Tasman Bay off the northern coast of the South Island of New Zealand.

Made of granite, it is in the shape of an apple which has been cut in half. It is a
popular tourist attraction in the waters of the Tasman Sea approximately 50 metres off the coast between Kaiteriteri and Marahau.
