摘　　要：应用地表露头样品的常规有机地球化学分析资料,从有机质丰度、类型、成熟度等方面,对新疆北部布龙果尔地区下石炭统黑山头组暗色泥岩进行评价.研究表明:黑山头组有机碳含量高,经风化校正后达中等烃源岩标准.有机显微组分由腐泥组、镜质组和惰质组组成,有机质类型为Ⅰ、Ⅱ1、Ⅲ型,处于高成熟演化阶段.虽然样品分析结果受地表风化作用影响严重,但该区下石炭统黑山头组暗色泥岩具一定的生烃能力.Formation outcrop samples in Bulongguoer Region, the authors evaluate dark mudstone on the abundance, types and maturity of organic matter. The resuks show that organic carbon content of Heishantou Formation is high. Correcting the weathering loss of organic carbon content, it belongs to medium source rocks. The organic macerals are composed of sapropel, vitrinite and inertinite. The organic matter are type Ⅰ, type Ⅱ 1 and type Ⅲ. And they are at the high-mature stage. Though analysis data of outcrop samples are greatly influenced by surface weathering, it is undoubtedly that dark mudstone of Lower Carboniferous Heishantou Formation in Bulongguoer Region has a certain hydrocarbon-generating potential.
