摘要: 通过野外露头详细观察、薄片鉴定、X射线衍射分析、微量元素分析等技术，对大河沿地区塔尔朗组细粒沉积岩矿物成分、沉积构造、岩性岩相类型及沉积环境进行研究。结果表明：塔尔朗组细粒沉积岩矿物成分以石英和方解石为主，含少量长石及黏土矿物；沉积构造类型包括较强水动力下的粒序层理、小型交错层理、脉状层理以及静水环境下的纹层状构造；以颜色、矿物成分、沉积构造等因素为依据将细粒沉积岩划分为5种岩相，包括灰黑色薄层状混合细粒岩相、深黑色页状黏土岩相、灰黑色纹层状混合细粒岩相、灰色薄层状粉砂岩相、灰白色页状灰岩相；岩石类型包括碳酸盐岩类、细粒长英沉积岩类、细粒混合沉积岩类3种岩石类型。塔尔朗组细粒沉积岩沉积期温暖湿润，整体上属于还原的半咸水—咸水湖盆的产物。

Abstract: With the technologies of field outcrop section description, identification of thin sections, whole rock X-ray diffraction(XRD)analysis and trace element analysis, researchers have studied mineral components, sedimentary structures, rock types and sedimentary environment of fine-grained sedimentary rocks in Taerlang Formation, Daheyan Area. The results reveal that fine-grained sedimentary rocks are mainly composed of quartz and calcite, and still contain a small amount of feldspar and clay minerals. The types of sedimentary structures contain normal graded bedding, flaser bedding, cross-beddings structure under the strong hydrodynamic and laminated structures under static water environment. It develops carbonate rocks, felsic rocks and fine-grained mixed rocks, and it is divided into 5 types of lithofacies based on factors of color, mineral composition and sedimentary structure, including grey thin-layered mixed fine-grained lithofacies, deep-black laminated clay lithofacies, grey laminated mixed fine-grained lithofacies, grey thin-layered siltstone lithofacies, and off-white laminated limestone lithofacies. The period of fine-grained sedimentary rocks was warm and humid, which belong to quiet, reductive, semi-salt and salt basin.
