Fresh and Altered Clay
Fresh and Altered Clay
(OP)
I am looking at some driller's logs from old (70s) well completion reports. They desrcibe layers of altered clay and also layers of fresh clay. Can someone explain what those descriptions mean?





RE: Fresh and Altered Clay
What part of the country/world is this from?
Is this a domestic type (potable)water well?
Was the driller a specialty-type? Water well, mineral exploration, etc???
Does the altered or fresh clay seem to describe alluvial sediments or rocks (formational units)?
