摘要

Over the past years a kind of red organic pigment was found in various strata in Chi-na. Recently, the authors have discovered the similar red pigment in a large-scale silver deposit hosted in the Sinian black shale, and confirmed that the pigment isan O- and N-rich heterocyclic 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.
