【摘要】 对全岩显微组分统计方法与应用进行了讨论。认为全岩样品粉碎至 1 mm粒度 ,用环氧树脂粘结 ,制成粉砖光片 ,在反射白光结合反射荧光下进行显微组分定量统计 ,点距和行距采用 0 .5 mm,有效统计点数大于 1 　0 0 0个 ,统计结果可比性好。提出的全岩有机质类型和丰度评价标准 ,经实例验证可靠 ,能有效地评价烃源岩的优劣 ,并首次定量划分出全岩有机质类型。与干酪根镜检分析方法相比 ,全岩显微组分定量统计方法具有明显的优越性 ,不仅能提供更丰富的信息 ,而且分析速度快、费用低、直观 ,因而是烃源岩有机岩石学研究的重要方法更多还原

【Abstract】 The statistical method and the application of whole rock macerals are discussed It is suggested that the grain size of whole rock samples are ground to 1 mm, bonded with epoxy resin,powder brick light section is made up.The quantitative statistics of macerals are conducted under reflected white light and fluorescent light, for which both point to point and line to line distances are 0 5mm,and effective statistical points are more than 1000 In this way, comparability of the statistical results is good The proposed evaluation standards of the type and abundance of whole rock organic matter are proved crediable by identifying samples, properties of hydrocarbon source rocks can be effectively evaluated Quantitative classification of the whole rock organic matter types is first established Compared with the method of kerogen microscopic detection, the whole rock quantitative statistical analysis of macerals can provide more information, it has some obvious advantages, such as fast, low cost and direct analysis, thus it is an important research method of organic petrology of hydrocarbon source rocks更多还原
