在一些细粒灰岩中,由于常常缺乏压实标志或标志比较模糊,因此很难区分机械压实作用和早期胶结作用。本文提出一种新的补充标志来评价细粒碳酸盐岩中的压实作用:沉积物中薄壁生物微体化石的变形。经研究表明,它们是压实的可靠标志。可识别出两种常见的保存方式:在早期胶结的灰岩中,生物微体化石呈球形至微变形;而遭受机械压实的碳酸盐岩中的生物微体化石总是呈扁平状。 In some fine-grained limestone, it is difficult to distinguish between mechanical compaction and early cementation due to the often lacking of compaction marks or emblems. In this paper, a new complementary marker is proposed to evaluate the compaction in fine-grained carbonate rocks: the deformation of thin-walled biofragons in sediments. Studies have shown that they are reliable symbols of compaction. Two common methods of conservation are identified: in the early cemented limestone, the biomimicry fossils range from spheroidal to slightly deformable; biofortified fossils in mechanically compacted carbonates are always flattened.
