摘　　要：梵净山地区板溪群红子溪组钙质岩系中广泛发育大理岩透镜体。形成此岩系的控制因素可能为振荡频繁的构造运动或气候条件。通过仔细观察,发现大理岩透镜体有条带状、似层状断续产出2种,初步认为透镜体是成岩过程中差异性压实作用的产物,不是某种环境沉积的透镜体。In Fanjingshan area,the marble lens of Hongzixi formation developed widely,the reason maybe is the tectonic movement and temperature condition which oscillate frequently.By close observation,banded and stratoid marble are founded,it＇s thought that the lens is the outcome of discrepancy compaction during the metallogenic period,but not the lens under some sedimentary environment.
