黄铁矿作为页岩体系中最具代表性的重矿物之一,对其进行微观特征识别对于页岩沉积环境研究具有重要意义。以四川盆地泸州Ι区五峰组—龙一1亚段为例,通过岩心矿物实验、扫描电镜观测、网络模型优化和特征参数统计,构建了适用于黄铁矿扫描电镜图像分割的网络模型,实现了基于草莓状黄铁矿参数对研究区沉积环境的判断。结果表明:

Pyrite, a significant heavy mineral in shale, aids in the comprehension of shale depositional environments. Referencing the Wufeng-Long1 subsection Formation of the Luzhou Block in Sichuan Basin, a network model for pyrite SEM image segmentation was established via core mineral experiments, SEM observations, network model refinement, and feature parameter analysis. The model assesses the sedimentary environment of the study block using pyrite framboid parameters.
