GEOL40490 Quaternary Geology

Academic Year 2021/2022

What is Quaternary geology?
Quaternary geology is the discipline that focuses on describing and understanding landforms and sedimentary records of the Quaternary Period. The Quaternary is the most recent major subdivision (period) of the geological timescale spanning the last 2.6 million years of Earth’s history. This time interval has been marked by dramatic and relatively frequent changes in global climate. Cold glacial stages alternated with warm interglacial stages, each leaving indicators of past climate in the geologic record. Major events occurred which have shaped or modified the surface of the Earth and deposited thick sediment sequences in basins. Global sea level has fluctuated as a result of changes in ice sheets holding freshwater on land. These changes have had important regional and global geodynamic effects; some of which are still measurable today.

Why study the Quaternary?
The study of the Quaternary helps develop a perspective of the scale and rates at which the many aspects of our landscape change, providing context for ongoing changes we observe today. The expertise of Quaternary geologists lies in their capacity to describe and interpret the geologic and geomorphic records of this period, to reconstruct past environmental change based on a diverse range of geologic archives, and to assess the impact of such changes on the Earth’s surface. This expertise has numerous applications, ranging from mineral exploration, hazard assessment, climate change research, aggregate estimation, and environmental management.
