The serpentine system (also called snake seeding) is a method employed in the organization of a competition to define the seeded teams and arrange them in pools. The n ranked teams that will be involved in the tournament are distributed in m pools according to the following algorithm :
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.
The mixture of brucite and serpentine formed by Reaction 1b has the lowest silica activity in the serpentinite, so that the brucite phase is very important in understanding serpentinization. [14] However, the brucite is often blended in with the serpentine such that it is difficult to identify except with X-ray diffraction , and it is easily ...
Polished slab of bowenite serpentine, a variety of antigorite.. Bowenite is a hard, compact variety of the serpentinite species antigorite (Mg 3 (OH)O 4 Si 2 O 5). [1] Classed as a semi-precious gemstone, [2] it has been used for tools, weapons and jewellery by the Māori in New Zealand, [3] [4] and for jewellery by Fabergé. [5]

Serpentine plants have strongly developed root systems to facilitate uptake of water and nutrients. [7] For example, Noccaea fendleri (aka Fendler's penny grass) is a hyper-accumulator of nickel and Sedum laxum expresses succulence. In some cases, symbioses with serpentine tolerant ectomycorrhizal help facilitate plants’ adaptation to edaphic ...
