Serpentinization is an important phenomenon in subduction zones that has a strong control on the water cycle and geodynamics of a subduction zone. [ 41 ] Here mantle rock is cooled by the subducting slab to temperatures at which serpentinite is stable, and fluids are released from the subducting slab in great quantities into the ultramafic ...
Serpentine subgroup (part of the kaolinite-serpentine group in the category of phyllosilicates) [1] are greenish, brownish, or spotted minerals commonly found in serpentinite. They are used as a source of magnesium and asbestos , and as decorative stone. [ 5 ]
Lizardite is a mineral from the serpentine subgroup [3] with formula Mg 3 (Si 2 O 5)(OH) 4, and the most common type of mineral in the subgroup. [4] It is also a member of the kaolinite-serpentine group. [5] Lizardite may form a solid-solution series with the nickel-bearing népouite (pure end-member: Ni 3 (Si 2 O 5)(OH) 4).
Serpentine group minerals have a Mohs hardness of 2.5 to 3.5, so serpentinite is easily carved. [26] Grades of serpentinite higher in calcite , along with the verd antique ( breccia form of serpentinite), have historically been used as decorative stones for their marble-like qualities.
Crinkle crankle wall in Bramfield, Suffolk. A crinkle crankle wall, also known as a crinkum crankum, sinusoidal, serpentine, ribbon or wavy wall, is an unusual type of structural or garden wall built in a serpentine shape with alternating curves, originally used in Ancient Egypt, but also typically found in Suffolk in England.
Typhon (/ ˈ t aɪ f ɒ n,-f ən /; Ancient Greek: Τυφῶν, romanized: Typhôn, [tyːpʰɔ̂ːn]), also Typhoeus (/ t aɪ ˈ f iː ə s /; Τυφωεύς, Typhōeús), Typhaon (Τυφάων, Typháōn) or Typhos (Τυφώς, Typhṓs), was a monstrous serpentine giant and one of the deadliest creatures in Greek mythology.
Serpentine soil is an uncommon soil type produced by weathered ultramafic rock such as peridotite and its metamorphic derivatives such as serpentinite. More precisely, serpentine soil contains minerals of the serpentine subgroup, especially antigorite, lizardite, and chrysotile or white asbestos, all of which are commonly found in ultramafic ...
It contains generally 1.5–2.5% nickel and consists largely of Mg-depleted serpentine in which nickel is incorporated. In pockets and fissures of the serpentinite rock green garnierite can be present in minor quantities, but with high nickel contents – mostly 20–40%. It is bound in newly formed phyllosilicate minerals. All the nickel in ...
