Ancylite-(Ce) occurs in quartz-calcite-chlorite veins crosscutting the foliation of phyllite in the Dewon Quarry in the foothills of the Opava Mountains of the eastern Sudetes, south-west Poland. Irregularly shaped grains of ancylite are up to 67 mm long and 22 mm wide. The compositional range of ancylite, determined by electron microprobe, is expressed by the empirical formula: (Sr 0.65-0.55 Ca 0.19-0.14 Fe 0.03-0.00 ) Σ0.87-0.69 (Ce 0.58-0.50 Nd 0.26-0,22 La 0.26-0.21 Pr 0.06-0.05 Sm 0.05-0.04 Gd 0.07-0.03 Dy 0.01-0.00 ) Σ1.29-1.05 (CO 3 ) 2 (OH 1.07-0.99 F 0.22-0.0.06 ) 1.29-1.05 . 0.95-0.93H 2 O. Ancylite crystallized directly from CO2-rich hydrothermal solutions as the last mineral in the veins following precipitation of calcite. The solution temperature, estimated using various chlorite geothermometres, was in the range of 260–340°C.

奥帕瓦山脉（波兰西南）千枚岩中石英-方解石-绿泥石脉中的 Ancylite-(Ce)

Ancylite-(Ce) 出现在石英-方解石-绿泥石矿脉中，横切波兰西南部苏台德东部奥帕瓦山脉山麓的 Dewon 采石场的千枚岩叶脉。不规则形状的 ancylite 颗粒长 67 毫米，宽 22 毫米。由电子探针确定的环长岩的组成范围用经验公式表示： (Sr 0.65-0.55 Ca 0.19-0.14 Fe 0.03-0.00 ) Σ0.87-0.69 (Ce 0.58-0.50 Nd 0.26-0.262 La -0.21 Pr 0.06-0.05 Sm 0.05-0.04 Gd 0.07-0.03 Dy 0.01-0.00 ) Σ1.29-1.05 (CO 3 ) 2 (OH 1.07-0.99 F 0.22-0.05.05) 0.95-0.93H 2 O. Ancylite 直接从富含 CO2 的热液溶液中结晶，作为方解石沉淀后矿脉中的最后一种矿物。使用各种绿泥石地温计估算的溶液温度在 260-340°C 范围内。
