  1. linings

    Snapshot Title: linings
    Taken by: kaufman

    Image: Contact between Fauquier Formation marble and Catoctin Formation greenstone, near Lime Kiln Road, Virginia
    Image Owner: Callan Bentley



    Description:

    Epidote and garnet line the cavity walls.



  2. veins

    Snapshot Title: veins

    Description:

    Garnet and epidote lined veins of coarse carbonate in Catoctin pillow basalt.



  3. injection

    Snapshot Title: injection
    Taken by: kaufman

    Image: Contact between Fauquier Formation marble and Catoctin Formation greenstone, near Lime Kiln Road, Virginia
    Image Owner: Callan Bentley



    Description:

    The coarse carbonate diapir appears injected from below. Higher temperatures of formation for these structures are reflected in oxygen isotope differences with the underlying finer grained carbonate....



  4. glassy rind

    Snapshot Title: glassy rind
    Taken by: kaufman

    Image: Contact between Fauquier Formation marble and Catoctin Formation greenstone, near Lime Kiln Road, Virginia
    Image Owner: Callan Bentley



    Description:

    The top (and bottom) of the pillow basalt is finer-grained than the interior indicating rapid quenching of minerals in direct contact with seawater.



  5. temperature

    Snapshot Title: temperature

    Image: Contact between Fauquier Formation marble and Catoctin Formation greenstone, near Lime Kiln Road, Virginia
    Image Owner: Callan Bentley



    Description:

    The fluidized carbonate injected between the pillows is very coarse grained relative to the source carbonate below, which we suggest was unconsolidated and within a few meters of sea level when the la...



  6. silicate reactions

    Snapshot Title: silicate reactions
    Taken by: kaufman

    Image: Contact between Fauquier Formation marble and Catoctin Formation greenstone, near Lime Kiln Road, Virginia
    Image Owner: Callan Bentley



    Description:

    The carbonate diapirs are lined with epidote and garnet formed by reaction of silicate minerals in the basalts with water and CO2. It is unclear whether these occured directly associated with the for...



  7. diapir

    Snapshot Title: diapir
    Taken by: kaufman

    Image: Contact between Fauquier Formation marble and Catoctin Formation greenstone, near Lime Kiln Road, Virginia
    Image Owner: Callan Bentley



    Description:

    Interpreted as a fluidized carbonate diapir between pillow basalt of the basal Catoctin volcanics.



  8. Scale

    Description:

    Each black rectangle is 1 cm long.
