OBJECTIONS TO BORON AS A FACIES INDICATOR

According to the research of the trace element boron conducted by the scholars at home and abroad, in combination with abundant data now available, the authors contend that boron may be used as a reliable criterion for identification of water body salinity, but not as a facies indicator. In this case, palaeontological and other sedimentary characteristics should be taken into account when boron is used as a criterion for recognition of ancient sedimentary environments.
