“…

We thank Professor Krinsley (KRINSLEY, 1971) for his interest in our paper, (WARNKE and STAUBLE, 1971) and are grateful for this opportunity to clarify a few points. We will discuss these points in the sequence in which they appear in Krinsley's remarks.It should be emphasized that our tentative conclusions are based on a set of observations and data different from the set presented by KRINSLEY et al (1964). Therefore, a modification of the views of Krinsley et al is not necessarily indicated.

“…Based on the number of such microstructures, Margolis and Kennett (1971) classify aqueous environments and their energy: from fluvial with single cracks, to low-energy beach environment, and to high-energy aqueous environment where the number of cracks is significant. Moreover, Krinsley et al (1964) say that the number of these cracks grows with the distance at which the grains are transported. On the other hand, however, the surfaces of grains of medium rounding (0.3-0.6 according to the Krumbein (1941) scale of rounding) and smooth and shiny surface (EM/EL), abrasion in the aqueous environment limited the number of V-shaped percussion cracks on the edges (Fig.…”

Age and sedimentological features of fluvial series in the Toruń Basin and the Drwęca Valley (Poland)

et al. 2011

Abstract:The deposits of the Toruń Basin are dominated by a few-metre thick sand series which fill up buried valley-like depressions. In many cases they underlie the Weichselian till which builds up the ice marginal streamway (pradolina) terraces or they are exposed at the basin slopes. As the results of the geological and sedimentological studies, as well as of the dating of the deposits at the sites in the Toruń Basin indicate, the deposits include two fluvial series accumulated before the advancement of the Leszno Phase ice sheet, i.e. in Middle Weichselian and at the beginning of Late Weichselian. The oldest fluvial series connected with the Saalian Glaciation was found at the mouth section of the Drwęca Valley. The fluvial system of the Toruń Basin during Middle Weichselian and at the beginning of Late Weichselian developed in two phases of the sand-bed braided river. During the first one the river channel were dominated by large mid-riverbed sandbars, while during the second phase the water flow was smaller and, as a result, low transverse sandbars and two-dimensional dunes developed. Other active river channel also showed low-energy flows, more intensive meandering than in the case of the braided rivers, as well as sandy side-bars. Analysis of the rounding and frosting of the quartz grains indicate that the studied series of the Weichselian sandy deposits represent alluvia of a river which were fed from two diverse sources. The first one might have represented the alluvia of a warm river which transformed its load, while the other one might have mainly carried the underlying Quaternary deposits.

“…The abundance and size of the V-shaped pits marked at locations 5, 6, 10 and 11 on the grains (Plate II(5 and 6, Plate III(10 and 11)) attribute for the long duration with high intensity of subaqueous agitation (Manickam and Barbaroux 1987) (Table 1). These features are associated with straight and curved scratches suggesting that quartz grains are transported by the fluvial environment (Krinsley and Takahshi 1962;Krinsley et al 1964). The conchoidal fractures, arcuate steps, striations and V-shaped marks are predominant in NE monsoon, which are attributed to high-energy conditions prevailing during NE monsoon.…”

Quartz surface microtextural studies of Cauvery River sediments, Tamil Nadu, India

2015

The spatially distributed sand samples of the Cauvery River sediments in Tamil Nadu were investigated with respect to their surface microtextural features in north-east (NE) and south-west (SW) monsoon rainfall seasons. The quartz grains show distinct surface microtextures with unique mechanical, chemical and morphological features with respect to the sedimentation process. The mechanical features like conchoidal fractures with arcuate steps indicate that the sand grains were derived from crystalline rocks. The abundance of angular grains supports that the grains were transported long distance by fluvial process. The silica globule, overgrowth and precipitation marks on the grain surfaces decipher the chemical process in silica saturated environment. Similarly, the solution pits in sand grains near Poombugar indicate the influence of sea water. The chatter mark trails suggest the wet tropical climate. The abundance of mechanical features and smooth surface microtextures suggest that the grains were transported in high-energy conditions. The NE monsoon sediments are coarse grained to medium grained and SW monsoon sediments are medium to fine sand size, which are attributed to the high and moderate energy conditions, respectively.
