摘要
地学幸存者效应模式图。在地质研究中,两个因素有相关性就一定有成因联系?在富有机质黑色页岩中,一般含不同数量的斑脱岩条带,数量相对较多(具有相关性),据此认为火山活动促进了生产力(具有成因联系)。页岩中还发现有大量重力流现象,认为重力流也可促进生产力。
A schematic diagram of the Geological Survivor Effect.In geological research,does the correlation between two factors necessarily imply a causal rela-tionship?In organic-rich black shales,there are generally varying numbers of bentonite bands,with a relatively large quantity(correlation).Based on this,it is assumed that volcanic activity en-hanced productivity(causal relationship).Abundant gravity flows have also been observed in the shale,which is suggested to enhance productivity.
