Is most hummocky cross‐stratification formed by large‐scale ripples?

JG Quin - Sedimentology, 2011 - Wiley Online Library
Although normal isotropic hummocky cross‐stratification is commonly interpreted to be the
deposit of large‐scale ripples, there are many reasons why this may not usually be the case …
