Soil depth is measured across the study catchment providing the first bedrock map of a basalt derived soil catchment.
Four surficial geology maps at 1 250,000 scale were produced from 14 maps scaled at 1 100,000, while a single compilation of six bedrock maps was generalized from 1 125,000 to 1 500,000 scale.
We compared the bedrock map with data about the pattern of the erosional resistance of Alpine rocks to identify the controls of the lithologic architecture on the location of overdeepenings.
Often the biggest delta systems are associated with the places where the bedrock map shows that there's large drainage basins". Simply put, there's just a lot of ice to melt in these areas, whether it enters the ocean directly in the form of icebergs or flows into it in the form of a river.
Or in Greenland where improved bedrock maps reveal a marine connection an average of 40 kilometers further inland than previously thought.
The topography of Greenland, prior to these uplift events is reconstructed from the present-day, isostatically compensated bedrock by mapping the two main steps in the landscape that resulted from the two uplift phases.
Here we present two case studies describing our approach to the generalization of surficial and bedrock geology maps, respectively.
We additionally used the bedrock topography map as a basis to calculate the erosional potential of the Alpine glaciers, which was related to the thickness of the LGM ice.
Bedrock geology maps ([35]) show the age, distribution and character of bedrock that lies immediately beneath the soils or surface.
While well locations have been accurately located within a few meters using GPS units, the digital version of the 1 500 000-scale bedrock geologic map of Maine to which we compare well data, has a positional accuracy of ∼0.5 1 km, further justifying the application of distance zones.
