I'm sorry, but after reading the article, I have no idea how the Sadler Effect works. "He showed that under these conditions it is inevitable that, on average, thinner stratigraphic sections, which cover shorter amounts of time, record faster accumulation rates than thicker sections, which record longer amounts of time." OK, he showed it, but what did he show? Describe the revelation, not just its effect! Wildbirdz (talk) 20:55, 29 June 2013 (UTC)Reply
I was puzzled by the phrase "bigger geological events - episodes of deposition, erosion, and the gaps between those events". It seems to define all parts of a geological record as "bigger events", including smaller events and periods where nothing is happening. 213.122.35.18 (talk) 21:04, 29 June 2013 (UTC)Reply
