Question 1

Till is a sediment and is perhaps more variable than any sediment known by a single name

Answer 1

Flint 1957

Question 2

Glacitectonite = rock/sediment deformed by subglacial shearing (deformation) but retains some of the structural characteristics of parent material which may consist of ig/met/sed rock or unlithified sediments

Answer 2

Benn and Evans 1996

Question 3

Subglacial traction till = sediment deposited by glacier sole sliding +/ deforming its bed, having been released directly from ice by P melting +/ liberated from substrate then disaggregated and completely/largely homogenised by shearing

Answer 3

Evans et al 2006

Question 4

Melt out till = sediment released by melting/sublimation of stagnant/slowly moving debris=riche glacier ice and directly deposited without subsequent transport/deformation

Answer 4

Benn and Evans 1998
