| Size oftlze clast | 2 to 64 mm (max. 50 cm) rafts of tuffs | Essentially < 4 mm lower parts contain 4 - 64 mm | Essentially < 4 mm lower layer contains cored lapilli (2 - 64 mm) | <4 mm | |||
| Type ofclast | Pumice, juvenile and epiclastic fragments. | Oxidized tuff fragments, pumice, consolidated soot. | Essentially pumice fragments. | Pumice epiclastic fragments. | |||
| Shape of clasts | Circular, elliptical pumice, lithics are angular. Rafts aligned parallel to bed. | Circular pumice, other fragments subangular to angular. | Spherical, elongated, gray ash pumice smaller clasts angular. | Spherical to elongate pumice. | |||
| Cohesiveness welding | Vitreous, brittle, well defined pumiceous zone lithified. | Well consolidated, glassy fracture, with brittle unconsolidated layers in between shale like fissility | Well indurated welded, with cherty balls, upper part loose and vesicular | Consolidated but friable | |||
| Cystals | Contains feldspar crystals | Certain sections contain crystal tuff, rest vitric | No crystals observed, in hand specimen | No crystal observed. | |||
| Structure (Depositional) | Cyclic deposit with graded bedding, reverse grading of pumice, normal grading of lithics, tongues observed, cross bedding in upper parts. | Moderately bedded, internal cross stratification and dune structure developed. | Thinly bedded bedding sags, reverse and normal grading of pumice and rock fragments. | Thickly bedded with no internal bedding | |||
| Association | Lying over an agglomerate, interbedded with non welded crystalline felsic tuff. | Overlying basalt flow, has intrusive relation at one place with associated basalt. | Interbedded with basalt, and agglomerate | Lying conformably over basalt | |||
| Thickness | about 20 m | >l00 m | 10 - 15 m | 10 m | |||
| Geometry of the deposit | Sheet, layered | Sheet, layered | Layered limited dimensions | Small fill type. | |||
| Bedform and other salient feature | Contains planer beds, with tongues of one sub layer protruding into other, margins of such tongues are chilled | Planar beds dune structure | Planar beds bedding sags, cherty lumps, cherty balls and cored/accretionary lapilli, upper beds contain only ash pumice. | Planar beds, thick bedding, surface has cavities of various sizes. | |||
