Micro-texture and in situ sulfur isotope of pyrite from the Baiyunpu Pb–Zn deposit in central Hunan, South China: Implications for the growth mechanism of colloform pyrite aggregates

Colloform pyrite textures have been detected in various geological bodies and have received much attention in recent years. Although these textures have been proved to be formed by the aggregation of micro-grains with different sizes, further work is needed to understand the mechanism for developing them. We carried out a detailed study on the micro-textures, crystal preferred orientations (CPOs), trace element, and sulfur isotope compositions...
