【摘要】 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。更多还原

【Abstract】 The origin of Carboniferous slag-like limestone in Chaohu,Anhui Province,has drawn wide attention and discussion.Three hypotheses have been proposed,relating its origin to chemical weathering,bioturbation,and seismic activities.These hypotheses emphasize geological processes in different sedimentary and diagenetic stages.On the basis of geological survey,we consider that a combination of geological,biological,and environmental factors have contributed to the formation of the slap-like limestone in Chaohu,Anhui Province.更多还原
