The main goal of the paper is the reconstruction of a Middle Triassic buildup cropping out in the central part of the Southern Apennines. Middle Triassic reefs of the western Tethys realm are well known in the Northern and Southern Alps. In contrast, few studies of the Anisian–Ladinian carbonate platforms of the southern Apennines are available, due to the diagenetic alteration and tectonic disruption that hinder their paleoenvironmental and stratigraphic reconstruction. In an attempt to fill this gap, and to improve the knowledge on the Anisian–Ladinian carbonates of central Mediterranean area, this research is focused on a carbonate buildup cropping out in the “La Cerchiara” area, Sasso di Castalda (Basilicata, Southern Italy). The buildup, affected by intense tectonic deformation associated with the development of the Apennine thrust and fold belt, was studied using a statistical evaluation of the quantitative microfacies data. The research enabled a reconstruction of the original stratigraphic relationships of the various buildup fragments. A positive linear regression between the sample positions vs the percentage of autochthonous carbonates indicates an increase of the autochthons carbonate toward the top of the succession. The allochthonous fabrics (packstone/wackestone) at the base of the section (Unit IIIa) pass gradually upward into autochthonous (boundstones) facies (Units IIIb, I), consisting of microbialites (clotted peloidal micrite, microbial-derived laminae, and aphanitic micrite), microproblematica and cyanobacterial crusts, with few encrusting skeletal organisms. Statistical data suggest that units IIIa, IIIb, and I are in stratigraphic order while unit II appears to have been moved by tectonic dislocation from its original position at the base of the succession. The absence of metazoan reef framework, and the richness of micro-encrusters, autochthonous micrite and synsedimentary cements, suggest a mud-mound style of growth for the carbonate bodies of the Southern Apennine during the Anisian.

该论文的主要目标是重建在南亚平宁山脉中部出现的中三叠世岩层。西特提斯界的中三叠世珊瑚礁在北阿尔卑斯山和南阿尔卑斯山是众所周知的。相比之下，由于成岩改变和构造破坏阻碍了它们的古环境和地层重建，因此很少有关于亚平宁山脉南部阿尼西亚-拉丁阶碳酸盐台地的研究。为了填补这一空白，并提高对地中海中部地区 Anisian-Ladinian 碳酸盐岩的认识，这项研究的重点是在“La Cerchiara”地区，Sasso di Castalda（巴西利卡塔，意大利南部） ）。堆积，受与亚平宁冲断带和褶皱带发展相关的强烈构造变形的影响，使用定量微相数据的统计评估进行了研究。该研究能够重建各种堆积碎片的原始地层关系。样本位置与原生碳酸盐百分比之间的正线性回归表明，原生碳酸盐朝着序列顶部的方向增加。剖面（单元 IIIa）底部的外来构造（泥灰岩/泥灰岩）逐渐向上进入本土（边界岩）相（单元 IIIb、I），由微生物岩（凝结球状泥晶、微生物衍生的薄片和隐晶质泥晶组成） )、microproblematica 和蓝藻结壳，几乎没有结壳的骨骼生物。统计数据表明，单元 IIIa、IIIb 和 I 处于地层顺序，而单元 II 似乎已被构造错位从其在层序底部的原始位置移动。缺乏后生动物礁格架，以及丰富的微结壳、原生泥晶和同沉积胶结物，表明阿尼西期南亚平宁碳酸盐岩体呈泥丘式生长。
