为研究六盘山盆地新生界沉积微相特征与沉积演化规律,以盆地周缘野外露头岩性、沉积构造与沉积微相特征为研究对象,对六盘山盆地新生界沉积微相与沉积演化进行研究。结果表明,六盘山盆地新生界发育始新统寺口子组、渐新统清水营组、中新统彰恩堡组与干河沟组,与下伏不同时代地层不整合接触;六盘山盆地新生界沉积相为冲积扇、辫状河、三角洲、湖泊及沙漠沉积;根据砂、泥沉积在纵向上的组合特征,识别出砂泥薄互层式、厚泥厚砂式、薄泥厚砂式、厚泥薄砂式4种沉积充填样式;受青藏高原隆升的影响,六盘山盆地填充初始期寺口子组以辫状河冲积扇为主,在横向和纵向上变化较大,高峰期清水营组蒸发强烈,以膏盐等碎屑岩为特色的湖相沉积为主,衰退期彰恩堡组南部以湖相为主,北部以河流相为主,消亡期干河沟组自下而上砾石增多,以河流相为主,整个新生界沉积微相反映了六盘山盆地新生代沉积演化过程。研究结果对六盘山盆地新生界沉积微相与沉积演化规律有了新认识,也为不同层位、不同沉积盆地的研究提供借鉴。
