Sometimes the running water cuts through the clayey soil and forms deep channels known as gullies. This is a type of soil erosion, called as gully erosion. Gully erosion occurs in the Chambal basin where it is called ravines. Photo credit: @nomadic_mohit #ravines #gullies #geologypage #geologystructure #geologystudent #geomorphology .

Sometimes we need much time to spend in defining the major fault. Fault gouge or fault breccia usually seemed like another lithology, but, we need to confirm it again. Is that fault zone or another bedding of lithology. Be careful.. #geologyisfun #geology #geologystructure #geologicalstructures #structuralgeology #fieldwork #borneo

Sovrascorrimento (particolari faglie inverse a basso angolo) del Piz de Puez. Le spinte hanno creato una rottura della roccia dove gli più vecchi (Dolomia Principale, Triassico superiore) sono spostati sopra strati più giovani (Marne del Puez, Cretacico). ~~~~~~~~~~~~~~~~~~~~~~~~~~ Overthrust or thrust (particular low-angle reverse faults) of the Piz de Puez. The thrusts have created a break in the rock where the older ones (Main Dolomite, Upper Triassic) are moved over younger layers (Puez Marl, Cretaceous). #geologiastrutturale #geologia #geology #geologystructure #mountains #montagna

World's largest quartz crystal cluster on display. Crystal gallery, Swakopmund, Namibia. Quartz crystal cluster on display in a museum in Namibia. This is the world's largest quartz cluster, it was discovered in 1985 at the bottom of a 45 metre deep cave in the Otjua mine near Karibib in Namibia. It weighs 14,100 kg and took three years to excavate and remove. The pictures do not belong to me. 📸 : GEOLOGY In #geology #geological #mineralogy #mineral #quartz #silica #quartzcluster #quartzmineral #mineralquartz #namibia #geologynamibia #structuralgeology #geologystructure #crystallography #crystals #crystallove #crystallovers #crystalsofinstagram #

Herringbone Structure..... The structure looks like fish skeleton ..It formed due to tidal effect, where the current periodically flows in the opposite direction. In the picture it's a mixture of planar structure and herringbone Structure 📸: This structure formed on the jodhpur sandstone. It's fun to watch this structure and identify paleoenvironment... #geology #geologyfield #geologyfieldwork #structuralgeology #fieldwork #geologicalscience #igneous #metamorphic #petrology #sedimentology #sedimentologystructure #geologystructure #herringbone #sandstone #fieldtrip #igneous #tidaleffect #tidal #sedimentary

•Vivekananda Rock• It is a spot that attracts hundreds of thousands of tourists every year. Most go there to marvel at the beauty of the Bay of Bengal, Arabian Sea and Indian Ocean converging on the southernmost tip of the Indian subcontinent or celebrate the point where Indian seer Swami Vivekananda is said to have gained enlightenment. But the rock island under the Vivekananda memorial is a geological wonder. It is the point from which India, Australia and Antarctica split, 160 million years ago. The rock is all that remains to mark that world changing event. . . . . . . 🔍@j.apoorvi 📋 @_priyanshu6901 @scribe_of_tomorrow . . . . . . #geologyofindia #geologyrocks #geologystructure #geoscience #earthscience #vivekanada #rocks #geology #geology #geologyintheuniverse #geologywonders #structuralgeology #geologyrocks

Desiccation cracks (also known as mud cracks) are sedimentary structures formed as muddy sediment dries and contracts. Crack formation also occurs in clay-bearing soils as a result of a reduction in water content.
