在缺少地表露头的沉积岩地区,获得古水流信息资料是很困难的。通过岩心了解古水流方向看来是解决这一困难的一种途径。Nanz(1960)、Arbogast(1960)、Pot-ter和Mast(1963)、Campbell(1968)以及Rodriguez和Pirson(1968)等讨论了解决这一问题的各种可行手段。他们所讨论的
In the absence of surface sedimentary rock areas, access to information on the ancient flow of information is very difficult. Understanding the direction of ancient currents through cores seems to be one way to overcome this difficulty. Nanz (1960), Arbogast (1960), Pot-ter and Mast (1963), Campbell (1968) and Rodriguez and Pirson (1968) discussed various possible solutions to this problem. They discussed
