A continuation of the current very successful investigations of sulphur isotopes of Lower–Middle Cambrian successions, but, especially the extension of the project to the coeval analyses of multiple sulphur isotopes (32S, 33S, 34S, and 36S) of carbonate associated sulphate (CAS), chromium reducible sulphur (CRS), and organically bound sulphur (OBS) offers the creation of a unique data set for this time interval. This would allow developing a qualitative and quantitative understanding of changes in the sulphur cycle and in the oceanic composition, and their effects to palaeoecologic and palaeoclimatic conditions of the Lower–Middle Cambrian. The systematic investigation of sulphur and carbon isotopes from carbonate and mixed carbonate-siliciclastic successions of West Gondwana (Spain, France), East Gondwana (Australia), Siberia, Laurentia, and East Avalonia will further deliver valuable proxies, representing an important potential for chemostratigraphic correlation of the Lower–Middle Cambrian boundary interval.

他将较低中部寒武纪继任的Surphur同位素的成功研究继续进行，他将其投影到多个Surphur同位素（32s，33s，34s，34s和36s）的共同分析的碳酸盐（CAS，CAS，CAS，CAS，CAS，可还原硫的硫（CRS），以及CRS，CRS），以及有机结合的硫（OBS）为AL提供了独特的数据集，对硫周期和海洋成分的变化产生了定量的定量理解，以及对古生物学和古气候的影响。西冈瓦纳（西班牙，法国），东冈瓦纳（澳大利亚），西伯利亚，劳伦蒂亚，劳伦蒂亚，劳伦蒂亚，劳伦蒂亚和东阿瓦洛尼亚将进一步提供代理，代表下较低的下层寒武纪剑术与较晚的相关性， 。
