钙质结砾岩是土壤剖面中细粒碳酸盐(典型的隐晶方解石)形成的次生堆积物。许多钙质结砾岩的构造和结构类似于迭层石的构造和结构,特别是类似于具扁平状隐晶质纹层、侧向连接的半椭球体沉积物(hemispheroids)和核形石。最重要的是区别这两种类型的沉积物,隐晶质沉积物是典型的潮汐带沉积物,也是范围狭小的潮下带沉积物,而钙质结砾岩是陆相风化作用的产物,经常与不整合相伴生。(钅监)定纹层状和豆状钙质结砾岩的常见特征有下列几方面:
Calcareous conglomerates are secondary deposits of fine-grained carbonate (typical cryptocrystalline calcite) in the soil profile. Many of the calcareous conglomerates have structures and structures that are similar to those of laminated rocks, especially similar to flattened cryptocrystalline layers, laterally connected hemispheroids and nuclei. The most important thing is to distinguish between these two types of sediments, which are typical tidal zone sediments and also a small range of subtidal sediments, whereas calcareous conglomerates are the product of continental weathering. Often associated with unconformity. (钅 监) The regular features of laminar and bean-like calcareous conglomerates are as follows:
