摘要
康玉地区中、晚侏罗世发育一套非同寻常的重力流沉积（拉贡塘组），主要有颗粒流、泥石流及浊流沉积三种类型。属次深海—深海（斜坡—盆底）环境，由断裂活动引起的岩崩、滑塌、块体流、浊流等的沉积产物。
A complex suite of gravity flow deposits in the Lagongtang Formation is well devel- oped in the Middle and Late Jurassic strata in the Kangyu region,Xizang.These gravity flow deposits consist of the grain flow,debris flow and turbidity current deposits,and may be interpreted as the products of rockfall,slumping mass flow and turbidity currents trig- gered by faulting in the bathyal-abyssal (slope-basin floor) environments.
