The Ediacaran Doushantuo Formation in Weng’an and Fuquan areas of the Guizhou Province in southern China hosts highgrade phosphorus ore deposits and exceptionally wellpreserved phosphatic microfossils that are commonly less than 1 mm in diameter. Earlier studies attributed these fossils to algae or acritarchs. In the last decade, researchers found that the spherical microfossils, in a large proportion, show metazoan embryonic development features with early cleavage stages. Thus these spherical microfossils have been considered as diploblast or triploblast embryos and resting eggs of early animals. However, reliable fossils similar to blastula, gastrula embryos, fossils of larvae after hatching, and particularly, the corresponding body fossils of these animal embryos have never been found in the relevant strata. This phenomenon challenges the interpretation that these globular microfossils are animal embryos. Because the major uncertainty on these fossils is whether they are animals or plants, a detailed geochemical analyses across the fossils may help to reveal the differences (between animal and plant) in the composition of cell membrane / wall and cell inclusions, the pattern of physiological metabolism, and the phosphatized mechanisms in particular depositional environments. On this basis and in combination with morphological comparison with the Cambrian microfossils and modern metazoan embryos, elemental geochemistry across the spherical microfossils (“embryos”) of the Weng’an biota may provide new information for better understanding the genetic affinity of the Doushantuo globular fossils. In this paper, the author analyzes the microfossils collected from Weng’an and Fuquan areas in Guizhou by electron probe microanalyzer (EPMA) to obtain trace elemental geochemistry across the globular fossils. For comparison purposes, two types of fossils have been analyzed, including fossils with tumorlike outer wall and those with polygonal plateshaped outer wall. Comparing results from these fossils and their host rocks, preliminary findings are as follows: (1) fossils with tumorlike and plateshaped outer walls have similar trends in major element contents from inside to the outer wall, suggesting the same affinity of the two groups; (2) comparison with the host rocks, the globular fossils have higher P, Ca content and stronger capability of assimilation and accumulation for Na, Ni, Zn, and Cl, but less capacity for the absorption of Mg, K, Al, Si, Ti, Mn and Fe2+. In addition, fossils have high S content and are enriched in lanthanide elements (ie. La, Ce, Nd). Through these analyses, the author prefers to exclude the seaweed affinity of these fossils. However, due to the lack of comparative data related to metazoan, the existing data is not sufficient to clarify the dispute on the classification of spherical microfossils.
