We carried out combined micropaleontological, microfacies and multivariate statistical analyses of benthic foraminiferal assemblages on a previously undocumented lowermost Cretaceous carbonate succession from the western part of the Getic Carbonate Platform (Pui-Bănița zone, Southern Carpathians). The microfacies analysis and interpretations suggest that these limestones were developed under peritidal settings within different zones of a shallow-water inner platform paleoenvironment (bioclastic grainy bars, subtidal–intertidal flats and intertidal–supratidal ponds), where benthic foraminifera, microbial microstructures and calcareous algae were the main carbonate producers. The well-preserved micropaleontological content (mostly benthic foraminiferal assemblages) is important for lowermost Cretaceous Neotethyan biostratigraphy and allows the recognition of the Valanginian stage within this part of the Getic Carbonate Platform. The multivariate data processing (diversity indices, cluster analyses and principal components analyses) performed on the benthic foraminifera assemblages provide valuable information about their compositional patterns, diversity trends and spatial distribution with respect to the main facies zones. The results obtained through these analyses are extremely useful for the recognition of common/different paleoecological features and for a more precise interpretation of depositional paleoenvironments.

我们在Getic碳酸盐岩台地西部（喀尔巴阡山脉南部，贝伊-贝尼雅区）之前从未有过记载的最低白垩纪碳酸盐岩演替中，对底栖有孔虫组合进行了微古生物学，微相和多元统计分析。微相分析和解释表明，这些石灰岩是在浅水内部平台古环境的不同区域（生物碎屑颗粒状的条带，潮间带-潮间带和潮间带-上生池）的围岩环境下发育的，底栖有孔虫，微生物的微结构和钙质藻类是主要的碳酸盐生产商。保存完好的微古生物学内容（主要是底栖有孔虫组合）对于最低的白垩纪新特提斯岩生物地层学很重要，并且可以在Getic碳酸盐岩台地的这一部分中识别出瓦朗吉期。对底栖有孔虫组合进行的多元数据处理（多样性指数，聚类分析和主成分分析）提供了有关主要相带组成，多样性趋势和空间分布的有价值的信息。通过这些分析获得的结果对于识别共同/不同的古生态特征和更精确地解释沉积古环境非常有用。对底栖有孔虫组合进行的多元数据处理（多样性指数，聚类分析和主成分分析）提供了有关主要相带组成，多样性趋势和空间分布的有价值的信息。通过这些分析获得的结果对于识别共同/不同的古生态特征和更精确地解释沉积古环境非常有用。对底栖有孔虫组合进行的多元数据处理（多样性指数，聚类分析和主成分分析）提供了有关主要相带组成，多样性趋势和空间分布的有价值的信息。通过这些分析获得的结果对于识别共同/不同的古生态特征和更精确地解释沉积古环境非常有用。
