Robert Handford 第六讲、陆棚和斜坡 储层沉积学 陆棚在海洋中所处的位置 陆棚沉积环境的划分 陆棚的分类 1.按水体深状况分类 ①内陆棚（浅海陆棚）；②外陆棚（半深海陆棚） 2.按水动力状况分类 ①潮控陆棚；②浪控陆棚 3.按沉积物类型分类 ①泥质陆棚（浅-半深海陆棚）；②砂质陆棚（浅 海陆棚）；③碳酸盐质陆棚（碳酸盐缓坡-台地） ④混积陆棚 内陆棚与外陆棚与水体的深度关系 潮控陆棚-潮控大陆架沉积底形类型 a.底形变化；b.物源较少的情况；c.物源较丰富的情况 南黄海潮控陆棚的辐射状砂脊 浪控陆棚-浪控大陆架沉积底形类型和风暴流成因 陆棚泥；陆棚砂：风暴流沉积 浪控陆棚-浪控大陆架陆棚砂体的垂直和横剖面 浪控陆棚风暴流沉积理想剖面结构 风暴流堆积形式和剖面结构的实例 东南非洲陆棚沉积相立体图 不同沉积体系域的陆棚 沉积模式
