  • Glauconite - Wikipedia
    Glauconite is an iron potassium phyllosilicate (mica group) mineral of characteristic green color which is very friable [5] and has very low weathering resistance It crystallizes with a monoclinic geometry
  • Glauconite: Mineral information, data and localities.
    The green "glaucony" mineral commonly found in marine sediments has been defined as a mixed-layer glauconite-smectite (Odin Létolle, 1980) but in part it can actually be a mixture of minerals from the mica, serpentine and chlorite groups, rather than a pure glauconite mineral
  • Glauconite | Clay Mineral, Marine Sediment, Greenish-Gray | Britannica
    Glauconite forms by three principal processes: alteration of the fecal pellets of bottom-dwelling organisms; modification of particles of illitic and biotitic clays by seawater; and direct precipitation from seawater
  • Glauconite: A tricky, sticky mineral that’s challenging offshore wind . . .
    Offshore wind developers are encountering an unexpected challenge on the East Coast seafloor: a crushable, green mineral called glauconite, sometimes precisely where they plan to install wind turbines
  • 40 Facts About Glauconite
    Glauconite, often spotted as green grains in sedimentary rocks, is a mineral that forms under specific conditions in marine environments It's part of the mica group, known for its rich green color, which it owes to its iron potassium phyllosilicate content
  • Glauconite – WGNHS – UW–Madison
    Glauconite is considered diagnostic of sediments deposited in a continental shelf marine environment It is suggestive of slow rates of sediment accumulation and may form by biogenetic or diagenetic alteration of minerals such as biotite or volcanic glass
  • Glauconite - Sandatlas
    Glauconite is usually a component of sandstones It occurs in sand-sized granules in marine sandstones If abundant, it gives distinct green color to sandstones that are called greenbeds or greensands It may also occur in carbonate rocks
  • Glauconite - an overview | ScienceDirect Topics
    Glauconite is defined as a sheet silicate mineral belonging to the mica group, characterized by a strong affinity for water and variable chemical composition, often contributing to high density, neutron porosity, and gamma activity in sedimentary rocks It is particularly significant in older rocks where smectites have diminished due to diagenesis
  • Glauconite Mineral Data
    From the Greek "glaucos" for the blue green color Comments: Green glauconite intermixed with quartz Location: Ightham, Kent, England Scale: See Photo Blue green, Green, Yellow green Micaceous - Platy texture with "flexible" plates Non-fluorescent
  • Glauconite Geology And Applications - Nature
    Glauconite is a key clay mineral whose formation in shallow marine settings offers essential insights into sedimentary processes and palaeoenvironmental conditions
