This method is applicable to any deposits of calcium carbonate materials, in order to be investigated for coccoliths, whether or not being identified as chalk.
There is a need in agriculture and lime industry to identify the origin of the calcium carbonate rocks, whether or not these depositions came from coccolithic flagellates forming chalk or by other origin forming other calcium carbonates. By diagenesis as geological process all calcium carbonates can end up as denser and compact limestones, but for potential efficiency as agricultural liming materials and the classification in standardisation and regulations it is necessary to identify chalks by their coccolithic origin. Transition calcium carbonates can also occur as a mixture of coccoliths with other carbonate yielding organisms.
