Abstract

Bermuda wind-blown limesands are lobate-shaped bodies composed internally of leeward foreset strata which dip at 30 to 35 degrees and windward strata which dip at 10 to 15 degrees in an opposite direction. The foreset beds are convex upward. This convex upward cross-stratification is preserved because of the early stabilization of the eolian calcareous sand due to surface cementation by percolating rain water.
