==Definition of source rock==
A source rock is a rock that is capable of generating or that has generated movable quantities of hydrocarbons.
==Definitions of source rock types==
Source rocks can be divided into at least four major categories:
* Potential
* Effective
* Relic effective
* Spent
These categories and their definitions are shown in the table below.
{| class = "wikitable"
|-
! Type
! Definition
|-
| Potential source rock
| Rock which contains organic matter in sufficient quantity to generate and expel hydrocarbons if subjected to increased [[thermal maturation]].
|-
| Effective source rock
| Rock which contains organic matter and is presently generating and/or expelling hydrocarbons to form commercial accumulations.
|-
| Relic effective source rock
| An effective source rock which has ceased generating and expelling hydrocarbons due to a thermal cooling event such as uplift or erosion before exhausting its organic matter supply.
|-
| Spent source rock
| An active source rock which has exhausted its ability to generate and expel hydrocarbons either through lack of sufficient organic matter or due to reaching an overmature state.
