Well now, fine sediments being deposited seasonally in a quiet lake environment wouldn't demonstrate erosion, now would they? I believe erosion requires some external input of energy...yes, I read about that somewhere. Let's see, oh here's a definition:
Erosion - 1. the part of the overall process of denudation that includes the physical breaking down, chemical solution and transportation of material. 2. Movement of soil and rock material by agents such as running water, wind, moving ice, and gravitational creep. (from the Concise Oxford Dictionary of Earth Sciences, 1991)
Now, on to liquifaction:
Liquifaction - The process of becoming or making a liquid by heating, cooling, or a change in pressure. In soils, the temporary transformation of material to a fluid state due to the sudden decrease in shearing resistance caused by a collapse of the structure associated with a temporary increase in pore fluid pressure. (from the Concise Oxford Dictionary of Earth Sciences, 1991)
Please provide geological evidence that varves are always found in regions that have undergone structural collapse.
That's the normal definition of liquifaction. Sorry you weren't able to pick up on that, it seemed obvious enough at the time. In the context in question, "liquifaction" meant the covering of large areas of the Earth with water.
