距国际煤和有机岩石学委员会(ICCP)讨论制定新的显微组分分类近30年后,国际煤地质学杂志(International Journal of Coal Geology)于2017年发表了类脂体新的分类方案“Classification of liptinite - ICCP System 1994”。在此之前,ICCP发表了镜质体(ICCP,1998)、惰质体(ICCP,2001)和腐植体(Sykorova等,2005)的分类方案。类脂体新分类方案的发表,标志着ICCP完成了对煤显微组分分类体系的构建。这四个分类方案统称为“ICCP System 1994”。与ICCP的旧分类方案(Stopes Heerlen分类)相比,该类脂体分类适用于所有煤化作用程度的煤和变质程度的沉积岩中的分散有机质。新的类脂体分类方案包括9种显微组分,即角质体、木栓质体、孢子体、树脂体、渗出沥青体、叶绿素体、藻类体、类脂碎屑体、沥青质体。“ICCP system 1994”和中华人民共和国国家标准《烟煤显微组分分类》(GB/T 15588—2013)相比,后者有树皮体和荧光体,并明确地划分出了显微亚组分(即孢粉体分为大孢子体和小孢子体,藻类体分为结构藻类体和层状藻类体)。“ICCP system 1994”有叶绿素体,并将荧光体作为树脂体的一种。其他显微组分在国家标准《烟煤显微组分分类》和“ICCP System 1994”中相互对应。与“ICCP system 1994”的适用范围不同,国家标准《烟煤显微组分分类》适用于中阶煤。
A new classification scheme for liptinite maceral group was published in the International Journal of Coal Geology in 2017,nearly 30 years after the International Committee for Coal and Organic Petrology (ICCP) discussed and formulated the new classification of macerals,namely“Classification of liptinite ICCP system 1994”.Prior to this,ICCP published classification schemes for vitrinite (ICCP,1998),inertinite (ICCP,2001) and huminite (Sykorova et al.,2005).These four classification schemes are collectively referred to as the“ICCP System 1994.”In contrast to the previous ICCP (Stopes Heerlen) classification system,this new classification system is applicable to coal of all ranks and dispersed organic matter.The macerals of the liptinite group in the ICCP System 1994 are cutinite,suberinite,sporinite,resinite,exsudatinite,chlorophyllinite,alginite,liptodetrinite,and bituminite.Compared with “ICCP system 1994”,the National Standard of the People’s Republic of China,namely“Classification of Macerals for Bituminous Coal”(GB/T15588—2013),has barkinite and fluorinite,and clearly distinguishes maceral subgroups,(i.e.,sporopolle is divided into macrospores and microspores,and alginite is divided into telalginite and lamalginite.“ICCP system 1994” has chlorophyllinite,and considers fluorinite as a variety of resinite.All the rest macerals correspond to each other between the National Standards “Classification of Macerals for Bituminous Coal”and“ICCP System 1994”.Different from that of “ICCP system 1994”,the National Standard GB/T15588—2013 is applicable to middle rank coals.
