Abstract:
The reflectances of zoolite organic debris (including graptolites chitinozoans and scolecodonts) from Lower Paleozoic inJiangsu are well studied in this paper.The results show that they have extremely similar optical properties and variational regularities withvitrinite reflectances that is their reflectances increase with increasing of depth thus they all can be served as good indexes of organic maturity.Furthermore the correlations between them and vitrinite reflectances are established respectively by using conodont CAI as a link therefore the criteria of their maturity are given which has laid the foundations for their actual application.
