To define a basin, we follow the steps listed in the table below.
To define a basin, we follow the steps listed in the table below.
# Define the outline of the basin and important regional structural features.
# Map total sediment thickness.
# Identify subbasins ([[depocenter]]s and minibasins).
# Map age and location of oil and gas fields.
# Map age and location of [[source rock]]s.
==Basin outline and structural features==
==Basin outline and structural features==
The particular study area, whether only a part of a basin or an entire basin itself, should be identified on a large-scale geographic map using total sediment thickness as the primary control. We then map major regional structural features. If postdepositional deformation has resulted in [http://www.usgs.gov/science/science.php?term=353 erosion], we construct a paleogeographic restoration to approximate the original depositional basin outline (see [[Paleogeography]]).

Hydrocarbon types reflect the composition of the [[Kerogen types|kerogen]]s from which they were generated and provide an estimate of the potential number of source-rock intervals or variations of kerogen facies within a [[source rock]]. We can prepare or locate a map showing the distribution of [[hydrocarbon type]]s.
