Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.
) is an earth science concerned with the solid Earth, the rocks of which it is composed, and the processes by which they change over time.
There are over forty such techniques, each using a different radioactive element or a different way of measuring them.
It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, present a coherent picture in which the Earth was created a very long time ago.
It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks.
By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth.
In practical terms, geology is important for mineral and hydrocarbon exploration and exploitation, evaluating water resources, understanding of natural hazards, the remediation of environmental problems, and for providing insights into past climate change.
Geology also plays a role in geotechnical engineering and is a major academic discipline.
Evolutionary geologists consider that the top three metres (10 feet) of the Marlstone Rock Bed represent the whole of the Tenuicostatum Zone, the basal zone of the Toarcian Stage, Amongst the remaining quarries still ‘working’ the top of the Marlstone Rock Bed are the Hornton Quarries at Edge Hill near the village of Ratley, on the north-western edge of the Edge Hill plateau, some 10½ km (6½ miles) north-west of the town of Banbury (Figures 2 and 3).

When sampled, the fossil wood readily splintered, diagnostic of it still being ‘woody’ in spite of its impregnation with iron minerals during fossilisation.
