现代湖泊分析表明，在断陷湖盆可能发育洪水型、滑塌型两种成因的重力流沉积体系。本文综合利用岩心、测井、地震、野外露头及分析测试资料开展了民丰洼陷沙河街组及滦平盆地西瓜园组露头的洪水型重力流研究。通过宏观沉积构造、结构特征和岩石类型相结合的方法将洪水型重力流分为：块状中砾岩、叠瓦状中细砾岩、平行层理含砾中粗砂岩、波纹交错层理粉细砂岩、块状泥岩等14种岩相。识别出了六种岩相组合，可划分出砾质牵引流、砂质牵引流、砾质碎屑流、砂质碎屑流、砂质浊流、羽流六小类流体类型。洪水沉积作用细分为突发洪水型重力流和正常洪水型重力流两种，前者形成扇三角洲、近岸水下扇，后者形成湖底扇沉积。进一步识别出内扇、中扇、外扇亚相及平原泥石流、主水（沟）道、漫溢沉积、辫状水（沟）道、辫状水（沟）道间、朵叶体、浊积薄层砂及远端泥等微相单元；综合建立了洪水型重力流沉积模式，该模式强调了两种洪水型重力流的沉积交互作用及其响应过程。
