河流沉积

在河流沉积环境，石英砂的表面特征以次圆、贝壳状断口和水下撞击坑为主，显示了水流对石英砂颗粒表面的改造；

In the fluvial deposit environment , the quartz superficial characteristic is primarily by the inferior circle , the conchoidal breakage fracture and the submarine hit pit , revealing the transformation of current to the quartz ;

3000年来该地区古环境变化经历下列过程：2.45KaBP前有河流沉积环境的特点：色素指标为零，C/N比值高达60～80等；

Before 2.45 ka BP , fossil pigment was not found in sediments , and C / N was obviously high and even reached 60 - 80 , characteristic of fluvial facies .

该方法是著名河流沉积学家Miall（19851988）提出的。

Proposed by the famous sedimentologist Miall ( 1985 , 1988 ) .

230.1～156.2m间为较长时段的湖泊沉积环境过程，在期间曾出现过短暂的河流沉积环境过程；

230.1m ~ 156.2m , mainly deposit of lacustrine facies , in which there is a short-term deposit of fluvial facies ;
