Occurrences and Formation Mechanisms of Botryoidai Structures from the Sinian Dengying Formation,Sichuan Basin,China

摘要

Objective This study aims to characterize the occurrences and interior structural features of botryoidal structures from the Sinian Dengying Formation in the Sichuan Basin of Southwestern China,and to shed light on their formation mechanism.Method Based on the observation of outcrop and drilling cores,this study carried out polarizing microscope analyses and cathodoluminescence microscope analyses with respect to the botryoidal structures.
