安徽巢湖地区炉渣状灰岩的成因主要有三种假说,即风化作用、生物扰动、地震作用等三种假说从沉积过程的不同阶段做出相异解释,恰好说明了炉渣状灰岩的成因是多因素、多阶段的。在地质勘察的基础上,结合“地质—生物—环境”三者之间的相互影响探讨炉渣状灰岩的综合成因。 Three main hypotheses about the origin of slag-like limestone in Chaohu area, Anhui Province, are three kinds of hypotheses: weathering, bioturbation and earthquake. Different explanations are made from different stages of the deposition process, which shows that the origin of slag-like limestone is more Factors, multi-stage. On the basis of geological survey, combined with the “geology - biology - environment ” the interaction between the three to explore the comprehensive cause of slag limestone.
