The underpinning problems of deep-water facies still remain unresolved. (1) The Tb, Tc, and Td divisions of the turbidite facies model, with traction structures, are an integral part of the “Bouma Sequence” (Ta, Tb, Tc, Td, Te). However, deposits

In this reply, I respond to 18 issues associated with comments made by Zavala (e.g., inverse- to normally-graded sequence, origin of massive sands, experimental sandy debris flows, tidal rhythmites, facies models, etc.), and 10 issues associated with

Yang et al. (2017b) have advocated the importance of hyperpycnites by using a genetic facies model proposed for deposits of hyperpycnal flows by Mulder et al. (2003). The problem is that the authors have ignored experimental flume results and other e

By their impressive paper title “Ichnological analysis of contourites: Past, present and future”, Rodriguez-Tovar and Hernandez-Molina (2018) have implied that the paper is about a comprehensive review of the topic in space (i.e., global) and tim

The U. S. National Aeronautics and Space Administration (NASA) has archived thousands of satellite images of density plumes in its online publishing outlet called ‘Earth Observatory’ since 1999. Although these images are in the public domain, the

This discussion of a paper by Van Loon et al. (2016), published in the Journal of Palaeogeography (2016, 5(4), 381–390), is aimed at illustrating that there are fundamental deficiencies, which include (1) incomplete etymological reasoning for propo

The purpose of this critical review is to address fundamental principles associated with contourites and other bottom-current deposits. The four basic types of deep-marine bottom currents are: (1) thermohaline-induced geostrophic contour currents, (2

At present, there are no criteria to distinguish soft-sediment deformation structures (SSDS) formed by earthquakes from SSDS formed by the other 20 triggering mechanisms (see a companion paper in Vol. 5, No. 4 of this journal by Shanmugam, 2016). Eve

During a period of 82 years (1931–2013), 39 genetic terms were introduced for various deposits. Of the 39 terms, only ten are meaningful in understanding the true depositional origin ( e.g. , turbidites), the remaining 29 are just jargons ( e.g. ,
