摘要
本文详细讨论了贵州织金地区早二叠世第一旋回海底喷发玄武岩浆对海相碳酸盐岩的碳、氧、锶同位素组成的影响,这主要表现为玄武岩浆喷发热事件导致了碳酸盐岩的δ^(1(?))C、δ^(18)O及^(87)Sr/^(86)Sr值的明显下降。
The paper discusses in detail about the influence of the first cycle basalt magma at the end of the early Permian in Zhijin area on the stable isotopic compositions of marine-carbonates, e. g. ,the hot event leads to obviously drop of δ^(13)C, δ^(18)O, and ^(87)Sr/^(86)Sr in carbonates
