Plastic, as a "flagship species", represents how deeply humans impact the environment. Although scarce, the presence of plastic and other anthropogenic materials in rocks has already been reported in the literature, however, so far, not in the Southern Hemisphere. Thus, the objective of the present study was to report and describe samples of sedimentary rocks containing anthropogenic items cemented with biogenic and siliciclastic material - anthropoquinas - and to discuss implications to the establishment of the Anthropocene and geodiversity conservation. Six samples of anthropoquinas were evaluated, presenting different technofossils (metal bottle caps, ship nail, plastic earring and plastic fragment) and composition (lithic and biogenic fragments). Energy Dispersive X-ray Spectroscopy was conducted on two samples, reflecting differences regarding their genesis. The description of these rocks is concerning and reflects how deeply human behavior influences various natural compartments. Therefore, studies on the effects of marine litter on geodiversity are strongly encouraged.
塑料作为一种“旗舰物种”，代表了人类对环境的深刻影响。尽管数量稀少，但已有文献报道了岩石中存在塑料和其他人为材料，然而，到目前为止，还没有在南半球发现过。因此，本研究的目的是报告和描述含有生物成因和硅质碎屑胶结的人为物品（anthropoquinas）的沉积岩样本，并讨论其对人类世的建立和地质多样性保护的影响。评估了六个anthropoquinas 样本，呈现出不同的技术化石（金属瓶盖、船钉、塑料耳环和塑料碎片）和组成（石质和生物成因碎片）。对两个样本进行了能量色散 X 射线光谱分析，反映了它们成因上的差异。对这些岩石的描述令人担忧，反映了人类行为对各种自然环境的深刻影响。因此，强烈鼓励开展关于海洋垃圾对地质多样性影响的研究。
