present are also typical of low energy lacustrine deposits and burrowing activities were also observed during the field studies in two of the studied sections which are preserved in massive mudstone beds intercalated within the rhythmites
In this paper, we study a particular example of a geosystem exhibiting rhythmic patterns: calcareous rhythmites
such as limestone-marl or limestone-shale sequences (Figure 1).
This section is focused on the mineralogical, geochemical and textural features of the phreatomagmatic deposits and the altered host rocks (marl-limestone rhythmite
and oncolitic limestones) surrounding the lamproitic edifice as a consequence of the volcanic activity.
Nevertheless, occasional dropstones in the clay rhythmites
of SU1 indicate that deposition from the bottom of the glacier which ran over or floated above the deep valley at Arumetsa may have taken place during Late Saalian time.
This section is constituted by a 22-m-thick marl-limestone rhythmite
belonging to the Lorente Formation, and comprises three upward-thickening sequences and a sponge-microbialite buildup (Fig.
IB, 8A), rhythmites
are well exposed for _100 m along the south side of a gully (Anderson 2011).
Neville Staple easing us through Fun Boy Three and Specials songs was a superb way to top off Friday night after Vintage Trouble had got us in the groove following the reggae and dub of The Rhythmites
. Neville's new take on Ghost Town is chilling in the light of the current double dip recession.
Sparkes (1985) recognized two distinct till units: an older one containing volcanic rocks and a younger one containing granitic debris; in places, the two are separated by proglacial-lake deposits (rhythmites
