  • ERA: Mesozoic
  • Period: Cretaceous (wiki, alpha)
  • Epoch: Upper Cretaceous (Cenomanian Age)
  • Formation: Unnamed igneous intrusion
  • Age: 105-95 million years ago
  • Lithology: Nepheline Syenite
  • Original location: 34.692862, -92.262696
  • Donor organization: Granite Mountain Quarries
  • Donor contact: Heather Thompson / Anthony Jones
  • Financial support:
    • Liebelt Family Foundation
    • Granite Mountain Quarries
    • John Rutherford Mitchell
  • MacNote: Next best economic quality mottled with lighter patches of coarser feldspar crystals. Sample was selected to illustrate internal variation of grain size and fracture fills. Note mottled appearance reflecting local changes in grain size and the sub parallel bands of coarser grained feldspars.
  • AGS note: Mottle color is late incipient alteration. Check your samples with a long-wave UV light at night – recent/ongoing studies indicate that a large percentage of syenite is composed of sodalite (it fluoresces a bright orange). Once the article is published, a large portion of syenite will most likely be referred to as Sodalite-Nepheline Syenite.

  • ERA: Paleozoic
  • Period: Pennsylvanian (wiki, alpha)
  • Epoch: Middle (Desmoinian)
  • Formation: McAlester
  • Age: 308-306 million years ago
  • Lithology: Sandstone
  • Original location: 35.473880,-94.272593 (map)
  • Donor organization: APAC, Arkola Preston Quarry

    • Chris and Lesa Moyer
  • MacNote: Sample selected to illustrate a 'typical' sandstone from the upper Arkoma Basin fill. Crinkle laminations formed by coalification of macerated plant material. This indicates an adjacent vegetated area being reworked by high energy waves and currents to produce sand sized particles of plant debris commonly called 'coffee grounds' in the modern. This lithofacies is common in marginal marine sand flats.
