Abstract
Over the past years a kind of red organic pigment was found in various strata in Chi([1-3]). Recently, the authors have discovered the simil ar red pigment in a large-scale silver deposit hosted in the Sinian bl ack shale, and confirmed that the pigment is an O- and N-rich heterocy clic compound. This pigment is so sensitive to temperature change that it may disappear completely in a narrow temperature range and a short time. Therefore, it can be used as an indicator for paleotemperature.
