Mapping the geology (structural and sedimentological) at 1:50,000 scale to help understand the geomorphology and land use is essential for context and explains some of the complications arising from:
Stratigraphic and sedimentological attributes in Hazara Basin Lesser Himalaya, North Pakistan: the irroleindeciphering minerals potential.
During the next two Antarctic summers, we will be collecting more geophysical, physical oceanographic, sedimentological and biological data from these pristine sites in the same locations, so we can compare the changes over time in the habitats that colonise new ocean floor in Antarctic fjords.
Using data from geomorphic, sedimentological, biological, and dating information from fossil reef cores at 16 sites at Cairns and Mackay, the study covered the period from before the last glacial maximum, the last time period during the last glacial period when ice sheets were at their greatest extension, about 20,000 years ago, when sea levels were 118 metres below current levels.
To understand the evolution of the reef system over 30 millennia, the team collected geomorphological, sedimentological, biological and geochronological information from 16 fossil reef cores across North Queensland, Australia.
These modifications may create sedimentological signatures such as load casts, flames, flexures, and dish-like and fold structures which help in tracing their origin, causes, and geotectonic settings of the sedimentary basin.

This surface is covered by the Middle Jurassic Genna Selole Fm, which has different sedimentological and petrographical characteristics and thicknesses according to its location and the morphology and evolution of the lower substrate.
