"The tuff is a rediposited layer of volcanic ash. Care must be taken to not date the material that it is mixed with. This led to the older dates"

Is this true? Is it true, that the tuffs usually contain, mixed, older material, and this was the reason, that tuff was dated older? Has somebody geological knowledges?
The tuff was dated with paleomagnetism and fission tracks too. Can these dating metods be "frauded" by the "few grains" of mixed older materials?

Give original references, not creationist sources. If you can't get the original references, the rule of thumb is that creationists lie.
