有孔虫壳中的微量元素受海水成分以及钙化过程中的物理和生物条件控制。由于可以根据控制因素校准贝壳成分，有孔虫微量元素为研究人员提供了一个强大的工具箱来研究海洋的化学、物理和生物进化。微量元素研究人员面临的一些最重要的挑战是（1）建立贝壳化学、海水成分以及物理和生物因素之间的精确关系； (2) 将元素示踪剂应用于过去，并考虑到影响代理解释的潜在复杂情况的范围； (3) 确定哪些次要因素（例如成岩作用）可能影响沉积后的壳化学。通过对控制贝壳组成的因素的精确了解，并结合稳定同位素，有孔虫微量元素应该为研究海洋和气候演化提供非常有力的工具。
Trace elements in foraminifer shells are controlled by seawater composition and the physical and biological conditions during calcification. Because it is possible to calibrate shell composition against the controlling factors, foraminiferal trace elements provide researchers with a toolbox of powerful proxies to investigate the chemical, physical, and biological evolution of the oceans. Some of the most important challenges faced by trace element researchers are to (1) establish precise relationships among shell chemistry, seawater composition, and physical and biological factors; (2) to apply elemental tracers to the past and take into account the range of potential complications that affect proxy interpretation; and (3) to establish which secondary factors such as diagenesis may affect post-depositional shell chemistry. With a precise knowledge of the factors that control shell composition, and in conjunction with stable isotopes, foraminiferal trace elements should provide a very powerful tool to study ocean and climate evolution.
