Characteristics

MTD 1

2.9

1.4

4.3

1.4

Mudclast bearing sediments and convolute bedding

MTD 2

7.3

39.5

46.7

36.5

Coherent bedding bounded by shear zones and topped by 8 cm thick turbidite

MTD 3

7.7

58.0

65.7

47.8

Mixed sediments and a 2 mm thick clay layer as potential shear zone at the base

MTD 4

0.5

66.4

66.9

48.8

Fluidized ash layer as primary structure but deformation due to coring disturbance and gas expansion cannot be excluded

MTD 5

18.5

75.9

94.4

58.1

Mixed sediments, mud clasts, convolute bedding, tilted strata with a sharp lower boundary (X-CT) as shear zone at the base

MTD 6

61.0

127.6

188.6

91.2

Chaotic and convolute bedding and mixing of ash with hemipelagic deposits intercalated with coherently bedded sediments; shear zones (X-CT) cannot be associated to the base; the base is defined as the top of underlying ash layer; 8 cm thick turbidite as upper boundary
