在白垩质、部分硅化的沉积物中选择和鉴定有孔虫可能是有问题的,就像纽芬兰海岭(IODP Expesion342 Site 1407)的大年(古新世)上部样品所经历的那样。超声波处理可以通过从测试中去除细粒物质来潜在地改善有孔虫的释放和识别,从而减少处理时间。然而,这一过程具有潜在的破坏性,并可能通过减少记录中脆弱的分类群来改变有孔虫组合的组成,类似于溶解的影响(Nguyen等人。2011年)。
The selection and identification of foraminifera in chalky, partially silicified sediments can be problematic, as was experienced with upper Danian (Paleocene) samples from Newfoundland Ridge (IODP Expedition 342 Site 1407). Ultrasound treatment can potentially improve the liberation and identification of foraminifera by removing fine-grained material from the tests, leading to reduced processing time. However, this process is potentially destructive and can alter the composition of foraminiferal assemblages by reducing fragile taxa from the record, similar to the effects of dissolution (Nguyen et al. 2011).
