摘要
菌类体(Sclerotinite)在国际和国内煤岩组分分类表中都属惰性组分。通常是指那些反射率较高的真菌遗体。菌类体的高反射率一般认为是由于含有几丁质、黑色素所造成。但这种成因解释并未得到证实,相反却有荧光几丁质的发现(M.Teichmuller 1989)。我们在对海拉尔盆地侏罗系的褐煤研究后发现,低反射率的凝胶化菌类体与高反射率的丝炭化菌类体一样广泛分布。高压釜热解试验证明,不同类型的菌类体热解活性差异很大。根据这种差异,我们将所研究煤中的菌类体划分为三种类型:活性菌类体,弱活性菌类体,惰性菌类体。活性菌类体与凝胶化组分相对应,按照其光性又可分为A,B两种亚型;其他两类菌类休的光学性质可分别与半丝组分及丝炭化组分相对应。
Through the reflectance and pyrolysis analysis of Jurassic coal, north east of China, it is believed that there are various types of vitrinization and fusinizotion sclerotinites. Those different kinds of sclerotinites have different activities in our low temperature pyrolysis experiments. According to those different pyrolysis activities,sclerotinites can be divided into three parts: Active sclerotinite; Subactive sclerotinite; Inactive sclerotinite. The former is often shown by vitrilization sclerotinite which could be further recognized as A or B subtypes. The second always linked with semifusinized sclerotinite. The last one include superfusinization and fusinization sclerotinite.
