PyBacktrack provides a model of tectonic subsidence on both oceanic and continental crust.\r\nOcean crust subsidence is based on a user-selected lithospheric age-depth model and the present-day unloaded basement depth.\r\nContinental crust subsidence is based on syn-rift and post-rift subsidence that is modelled using the total sediment thickness at the site\r\nand the timing of the transition from rifting to thermal subsidence. At drill sites that did not penetrate to basement,\r\nthe age-coded stratigraphy is supplemented with a synthetic stratigraphic section that represents the undrilled section,\r\nwhose thickness is estimated using a global sediment thickness map. This is essential for estimating the decompacted thickness\r\nof the total sedimentary section, and thus bathymetry, through time.\r\nAt drill sites on stretched continental crust where the paleo-water depth is known from benthic fossil assemblages,\r\ntectonic subsidence can be computed via backstripping. The workflow is similar to backtracking, but paleo-water depths and\r\ntheir uncertainties need to be supplied as part of the input.\r\n\r\nDocumentation\r\n-------------\r\n\r\n.. image:: https://readthedocs.org/projects/pybacktrack/badge\r\n :target: http://pybacktrack.readthedocs.io\r\n\r\nThe `documentation `_ covers the pyBacktrack Python package.
