Miscellaneous Traces on the Bedding Planes of Mezoproterozoic Sandstones in Licheng, Shanxi:Characteristics and Origin Analysis
Apart from common ripple marks, mudcracks, there are miscellaneous traces on the bedding planes of the Mezoproterozoic sandstones in Licheng Geopark, Shanxi Province, such as " lithic earthworm",arcuate traces, starry traces, whose forming processes can hardly be understood on the basis of mechanics. Having a preliminary analysis, it is considered that the meander burrow or Nereites, crossed-S-liked traces, 8-liked traces should be trace fossils formed by worms or microbially induced sedimentary structures (MISS) ; the starry traces, whose single trace is short line, commonly thins out on the two ends, and 3 single short lines composed a trilete, should be similar to reported ice-wedge traces. It is more valuable that gradually transitional characteristics can be found between these traces, which prompt that we should comprehensively and systematically study the origin of these traces.
