Three kinds of gravity flows, i. e. debris flow, grain flow and turbidityflow, are divided by the main support mechanism of sediments.
根据主要支掌机制，区内重力流沉积可以分为碎屑流、颗粒流和浊流沉积。

According to their petrological characteristics and relations with surrounding rocks, we can regard them as deep water carbonate rocks of the debris flow and turbidity current sediments.
据角砾灰岩的岩石学特征及其与围岩地层的组合关系，该角砾岩主要属岩屑流和浊流沉积的深水碳酸盐岩。

Self-purification curves are presented, percentages and rate constants of the purification are calculated, and influence of temperature, flow rate, and turbidity on self-purification are discussed.
