  1. 1954 lava flows

    Snapshot Title: 1954 lava flows
    Taken by: Julian Thomson (GNS Science)

    Image: lava flows of Ngauruhoe, New Zealand
    Image Owner: Julian Thomson (GNS Science)



    Description:

    These and similar flows that you can see on the slopes of the cone were erupted during the largest production of lava in New Zealand in historic times.



  2. Pukekaikiore

    Snapshot Title: Pukekaikiore
    Taken by: Julian Thomson (GNS Science)

    Image: lava flows of Ngauruhoe, New Zealand
    Image Owner: Julian Thomson (GNS Science)



    Description:

    This 1737m high hill is next to Ngauruhoe and is also made of lava. It may either be a remnant of a much older volcano, or a rounded bulge of viscous lava that was pushed up from a vent directly benea...



  3. Dyke

    Snapshot Title: Dyke
    Taken by: Julian Thomson (GNS Science)

    Image: Tongariro Red Crater, , New Zealand
    Image Owner: Julian Thomson (GNS Science)



    Description:

    This dyke shows well developed cooling joints.



  4. Dyke

    Snapshot Title: Dyke
    Taken by: Julian Thomson (GNS Science)

    Image: Tongariro Red Crater, , New Zealand
    Image Owner: Julian Thomson (GNS Science)



    Description:

    This vertical dyke stands out dramatically in the red crater. It represents a vertical wall of lava that pushed up through the surrounding rock before solidifying. The walls of the dyke cooled fastest...



  5. lava fall

    Snapshot Title: lava fall
    Taken by: Julian Thomson (GNS Science)

    Image: lava flows of Ngauruhoe, New Zealand
    Image Owner: Julian Thomson (GNS Science)



    Description:

    The lava flow went over a cliff here, almost smoothing it over in this area.



  6. Levees

    Snapshot Title: Levees
    Taken by: Julian Thomson (GNS Science)

    Image: lava flows of Ngauruhoe, New Zealand
    Image Owner: Julian Thomson (GNS Science)



    Description:

    This lava flow shows well developed side ridges or levees



  7. Geologists

    Taken by: Julian Thomson (GNS Science)

    Image: Marlborough Beach, New Zealand
    Image Owner: Julian Thomson (GNS Science)



    Description:

    These scientists from Japan are collecting samples to analyse the effect on plants of the meteorite impact that caused the extinction of the dinosaurs



  8. raised marine platform

    Snapshot Title: raised marine platform
    Taken by: Julian Thomson (GNS Science)

    Image: Marlborough Beach, New Zealand
    Image Owner: Julian Thomson (GNS Science)



    Description:

    This flat area has been raised up out of the sea over thousands of years by earthquake uplift



  9. K-T boundary

    Snapshot Title: K-T boundary
    Taken by: Julian Thomson (GNS Science)

    Image: Marlborough Beach, New Zealand
    Image Owner: Julian Thomson (GNS Science)



    Description:

    The line separating the light Cretaceous and the dark Palaeocene rocks is the K - T boundary. the saw marks were created by geologists when they removed a slab from here for exhibit in the Australian ...



  10. Drill holes

    Snapshot Title: Drill holes
    Taken by: Julian Thomson (GNS Science)

    Image: K-T boundary, Woodside Creek, NZ
    Image Owner: Julian Thomson (GNS Science)



    Description:

    These holes are where geologists have taken rock samples for palaeomagnetic analysis. They were studying the Earth's magnetic orientation roughly 65 million years ago when these rocks were laid down u...



  11. K-T boundary

    Snapshot Title: K-T boundary
    Taken by: Julian Thomson (GNS Science)

    Image: K-T boundary, Woodside Creek, NZ
    Image Owner: Julian Thomson (GNS Science)



    Description:

    This is the top of the Cretaceous and the start of the Tertiary. The thin dividing line is a layer of dark clay found at this level worldwide and thought to be the fallout from a huge meteorite impact...



  12. Glacial Moraine
