Detrital drape

The second visible event is an erosional hiatus at 11 mm although no detrital draping is apparent it is likely that this hiatus represents a major, long-term flooding event. The rest of the sample above the hiatus is dated to isotope stage IT, it is therefore assumed that the hiatus represents the isotope stage 12 glacial and Termination V. The hiatus has simply removed material it has not caused any visible alteration in the calcite or in the isotopes. [Pg.268]

The band of buff-colored, translucent pallisade calcite from 11 mm to 32 mm. Zone C, is relatively event-free, with only a few minor dissolution horizons or detrital drapes (not visible with the naked eye) representing short-term local flood events but not longterm glacial advance flooding. The isotopes show parallel oscillations and are somewhat more enriched than the upper zones of the sample. The oxygen isotopic values lie close to those of modern calcite in the cave, suggesting a moderately cool, wet climate similar to that of today. The oscillations in the carbon isotopic values follow the simple pattern of... [Pg.268]

The hiatus at 32 mm is minor, suggesting again a short-lived local event the detrital drape is only barely apparent, very little erosion of underlying calcite has taken place, and there is only a small gap in the dates below and above the hiatus. The hiatus marks a change in form from translucent buff-coloured, pallisade crystals to dense, laminated, light coloured, opaque crystals. [Pg.269]
