THE VIDEOCLIPS

These 16 videoclips illustrate some of the practical skills and

techniques used when undertaking geological fieldwork. The

techniques are demonstrated by Jess and Jack, two

undergraduates at the University of Liverpool.

Locality: Cwm Tydu, Ceredigion, Wales. GR: SN 356 575 BGS Map sheet: Llangranog Skills demonstrated: Jack is doing a basic description of the sedimentary rocks at this locality, identifying geological structures and recording his observations of these structures as field sketches. Locality: Aberystwyth Bay, Ceredigion, Wales. GR: SN 583 823 BGS Map sheet: Aberyswyth Skills demonstrated: Jess is doing a basic description of the sedimentary rocks at this locality. She is also identifying way-up structures and recording these structures, dip & strike and the younging direction in a field sketch. Locality: Hilbre Island, Wirral GR: SJ 187 876 BGS Map sheet: Liverpool Skills demonstrated: Jess is identifying geological structures, recording her observations as a field sketch and drawing a basic conclusion about the sequence of events that took place at this locality.  *Wind levels were high here so we have added subtitles.
Locality: Hilbre Island, Wirral, England GR: SJ 187 877 BGS Map sheet: Liverpool Skills demonstrated: Jack demonstrates how to set up a field notebook in the field and record basic information about a locality including data, weather conditions, hazards, and the aims of  his field investigation. He also shows how to use a 1:50000 OS map to locate the geological features he is studying and produce a six figure grid reference for the locality. Locality: Hilbre Island, Wirral, England GR: SJ 187 877 BGS Map sheet: Liverpool Skills demonstrated: Jack demonstrates how to describe an outcrop and identify different packages of sedimentary rocks. He then shows how to use a hand lens and grain size card to make observations about sedimentary rocks. Jack makes it clear that you need to take a close look at the rocks and when you record your observations you need to keep these separate from your interpretations. Locality: Hilbre Island, Wirral, England GR: SJ 187 877 BGS Map sheet: Liverpool Skills demonstrated: Jack demonstrates how to produce a graphic log or a visual representation of the vertical succession he has looked at and has described in a previous clip. Jack explains how to use a graphic log sheet. He makes it clear that the observations and interpretations have to be kept separate on the graphic log.
Locality: Traeth Bychan, Anglesey, North Wales GR: SH 517 846 BGS Map sheet: Anglesey Skills demonstrated: Here Jess demonstrates how to draw a generalised sketch graphic log for an outcrop where limestone units are exposed in a cliff section. Jess points out the conventions used to produce a graphic log (pictorial representation of the rock succession) and gives advice about information to record in the field about fossils.
Locality: Rhosneigr, Anglesey, North Wales GR: SH 316 326 BGS Map sheet: Anglesey Skills demonstrated: At this locality Jack is identifying different geological structures developed in interbedded mudstones and sandstones. He demonstrates how to recognise antiforms, synforms, cleavage and refracted cleavage. He shows how way-up structures can be used to indicate younging direction and demonstrates how information about geological structures may be recorded in a field sketch. Locality: Moelfre, Anglesey, North Wales. (Moelfre harbour and Y Swnt headland) GR:SH 512 863 & SH 517 867 BGS Map sheet: Anglesey Skills demonstrated: At Moelfre, Jack visits two localities where limestones are exposed. At the first locality Jack demonstrates how to measure apparent dip. At the second locality Jack demonstrates how to measure dip and strike on uneven bedding planes. He shows how to record these structural measurements in a field notebook and shows how to identify the type of limestone exposed in the Y Swnt headland at Moelfre. Locality: Moel Findeg, Clwyd, North Wales GR: SJ 208 612 BGS Map sheet: Flint Skills demonstrated: Jess is demonstrating how to investigate a rock outcrop where packages of limestone and clastic sedimentary rocks are exposed. She also demonstrates how to complete a graphic log sheet that records the rock succession at this locality. Locality: Llanddwyn, Anglesey, North Wales GR: SH 391 634 BGS Map sheet: Anglesey Skills demonstrated: In this video Jack is investigating igneous rocks, describing these rocks and using way-up structures in the rocks to determine the direction of younging. Locality: Pothole valley, near Llanferres, North Wales GR: SJ 192 597 BGS Map sheet: Flint Skills demonstrated: Jack is looking at bedded limestones and demonstrating how to measure the dip & strike of the bedding in these rocks. He shows how dip & strike can be measured either by using a compass clinometer or by using a separate clinometer and a compass. Jack also explains how to set up a fieldwork notebook. Locality: Valley, Anglesey, North Wales GR: SH 285 802 BGS Map sheet: Anglesey Skills demonstrated: At this locality Jess is doing a basic description of the metamorphic rocks exposed here. She is identifying small scale geological structures, recording her observations as a field sketch and drawing her initial conclusion about the sequence of geological events that occurred at this locality. Locality: Porth Saint, Rhoscolyn, Anglesey, North Wales. GR: SH 261 758 BGS Map sheet: Anglesey Skills demonstrated: Here Jess is identifying larger scale geological structures (folds & faults) and recording her structural observations and apparent dip measurements in a field sketch. Locality: Traeth Bychan, Anglesey, North Wales. GR: SH 517 846 BGS Map sheet: Anglesey Skills demonstrated: At this locality Jack is investigating a cliff section, identifying a small igneous body intruded into layered sedimentary rocks and recording his observations on a field sketch. Locality: Porth-y-Post, Anglesey, North Wales GR: SH 243 796 BGS Map sheet: Anglesey Skills demonstrated: Here Jess  is identifying igneous bodies intruded into foliated metamorphic rocks and recording her observations on a field sketch.
