The PhD project focuses on the Pliocene as an analogue for potential future greenhouse conditions. The target study areas are in the Philippines. This project will model Neogene carbonates based on terrestrial mapping, using classig geologic fieldwork, Unmanned Aerial Vehicles and analysis of satellite-derived Digital Elevation Models. The outcomes of the project will shed new light on dimension and geometry of carbonate bodies, lateral dimensions of facies belts and palaeowater-depth. Attention will be given to the presence, in the geologic record, of facies that indicate rapid climatic or sedimentary changes, and to the relationship between the geological facies observed in the field and modern reefs. Data will serve as key data to integrate other data of the project, such as facies distribution, distribution of large benthic foraminifers and sedimentological features at outcrop scale.
Objectives of the individual project
- to produce stratigraphic logs and digital reconstructions of the different outcrops of Pliocene reefs;
- to quantify extension of facies belts and size and form of geobodies
- to quantify geometrical changes of reef growth patterns.
The project will develop "virtual outcrops" for each locality. Sequence stratigraphy, for example controlled by sea-level changes or uplift / subsidence, will be quantified with respect to changes in accommodation (base-level fluctuations). Spatial models further will allow the extension of facies belts to be quantified by ESR7.
