The diagram cross-plots the hydrogen:carbon (hydrogen index) as a function of the oxygen:carbon (oxygen index) atomic ratios of carbon compounds. Different kinds of organic matter are more likely to produce oil during thermocatalytic maturation than other types: Algae, type 1, H-rich, O-poor, tend to make good oils. Trees and other woody vegetation are made of type 3 organic matter, O-rich, H-poor, and are sources of coal and gas. This diagram is mostly used for differentiating different types of kerogen. ==See also== * Petroleum geology * Maturity (geology) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Van Krevelen diagram」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
