| Abstract: | A small honeycomb tafoni was found on the surface of the Meso-Neoproterozoic sandstone in Wafangdian area, Dalian, Liaoning Province. It is located on the surface of the northwest side of the outcrop sandstone layer. On the top surface of the sandstone layer and on the east and south sides, the tafoni was not developed. The whole tafoni is round or oval, with a diameter of 1-5cm and a depth of 1-2cm. Through field observation and comparative analysis, it is determined that it is the salt weathering tafoni. It is formed by the precipitation and crystallization of salt from sea fog in sandstone, which causes the detrital particles on the rock surface to fall off and weathering. |
